Map Scale and Projection

Have you ever seen a map the size of America? Or the size of the world? No? Then how are maps accurate if they are not the same size as the area they are representing? That’s where scaling comes into play. 

map scale is a way to represent the relationship between distances on a map and the actual distances on the ground. 

Map scales can vary greatly, depending on the size and purpose of the map. Large-scale maps, such as those used for city or street maps, have a small scale and show a lot of detail. Small-scale maps, such as world or regional maps, have a large scale and show less detail but cover a larger area.

Map scales are an important consideration when using maps, as they affect the accuracy and level of detail that can be represented on the map. It is important to choose the appropriate scale for the purpose of the map and the amount of detail needed.

The three most common forms are:

  1. Ratio

    1. 1 : 25,000

    2. The number on the left of the ratio is always the units of distance on the map

    3. The number on the right is always the unit of distance on Earth’s surface

    4. Every 1 inch on this map represents 25,000 actual inches on Earth’s surface.

  2. Written scale

    1. “1 inch equals 1 mile”

    2. Explains the relationship in words

  3. Graphic Scale

    1. There is a bar line marked on the map to show how much actual distance is covered

Okay, so there’s a good reason why maps aren’t as big as the actual area they are depicting. But how does a flat, 2D map on a piece of paper accurately represent our spherical Earth? 

Let’s talk about projections.

projection is a way of representing the curved surface of the earth on a flat map. Because the earth is a three-dimensional sphere, it is not possible to create a completely accurate flat map of the earth without distorting some of its features. Projections are used to minimize these distortions as much as possible, depending on the purpose of the map and the characteristics of the region being mapped.

There are many different types of map projections, each with its own set of strengths and weaknesses. Some common types of projections include:

  • Mercator projection: This projection is often used for navigation because it preserves angles, which is useful for plotting a straight-line course. However, it distorts the size of land masses near the poles, making them appear larger than they actually are.

  • Peters projection: This projection is designed to show countries in their true relative size, with minimal distortion. However, it distorts shapes and distances, making it less suitable for navigation.

  • Equal-area projection: This type of projection preserves the area of land masses, but distorts shape and distance.

It is important to choose the appropriate projection for the purpose of the map and the characteristics of the region being mapped. No single projection can capture all aspects of the earth's surface accurately, so trade-offs are always necessary.

Depending on what the cartographer wants to focus on, they have these four choices to make sure the globe fits on a paper:

  1. The shape of an area can be distorted

  2. Distance between two areas is inaccurate

  3. The relative size of different areas is inaccurate

  4. Direction can be distorted

Examples of Projection Families
  • Cylindrical projections are used for areas near the equator and the entire Earth, but with large distortions.

  • Conical projections are less distorted at mid- and high latitudes than cylindrical projections.

  • Azimuthal (or planar) projections are good for areas near the poles.

Two Important Types of Projections:

Robinson projection

The Robinson projection is a type of map projection that was developed in the 1960s by Arthur H. Robinson. It is a modified version of the Mercator projection, which is commonly used for navigation. The Robinson projection is designed to reduce some of the distortions of the Mercator projection, particularly near the poles, while still preserving some of its useful properties.

The Robinson projection is a compromise projection, meaning that it tries to balance out some of the distortions inherent in all map projections. It is not a perfect projection, and it still distorts the size, shape, and distance of land masses in various ways. However, it is generally considered to be a more visually appealing and useful projection than the Mercator projection for many purposes, such as world maps and atlases.

The Robinson projection is commonly used for world maps and other maps that aim to show the entire earth or a large region. It is not typically used for smaller-scale maps, such as street maps, because it distorts shapes and distances too much for such purposes.

Mercator projection

The Mercator projection is a widely used map projection that was first introduced by the Flemish geographer and cartographer Gerardus Mercator in 1569. It is a cylindrical projection in which the meridians (lines of longitude) and parallels (lines of latitude) are straight and perpendicular to each other, creating a grid-like pattern on the map.

One of the main characteristics of the Mercator projection is that it distorts the size of objects as the latitude increases from the Equator to the poles. This means that objects near the poles, such as Greenland and Antarctica, appear much larger on a Mercator map than they actually are, while objects at the Equator appear smaller.

The Mercator projection is still widely used today, especially in online maps and navigation systems, because it is simple to construct and easy to use for activities such as plotting straight-line courses. However, it is not considered to be a particularly accurate representation of the Earth's surface, and other projections such as the Peters projection or the Gall-Peters projection have been developed to address this issue.

  • Accurate shape and direction

  • Map is rectangular 

  • Size of poles are distorted

Geographic Grid

There are imaginary grid patterns drawn on Earth’s surfaces that tell us specific locations. 

Grid patterns are a type of spatial pattern that is characterized by a regular arrangement of objects or features in a grid-like structure. Grid patterns can be found in many different contexts, such as:

  • Urban planning: Many cities and towns are laid out on a grid pattern, with streets and blocks arranged in a regular pattern.

  • Agriculture: Some farming techniques, such as square foot gardening, involve planting crops in a grid pattern.

  • Landscaping: Grid patterns can be used in landscaping to create a formal, structured look.

  • Computer graphics: Grid patterns are commonly used in computer graphics to create structured backgrounds or to align objects.

Grid patterns are often used because they are simple and easy to understand, and they can be efficient in terms of the use of space. However, they can also be rigid and monotonous, and they may not always be the most aesthetically pleasing.

  • Parallel: arcs in circles around the LAP of the earth

    • Location of parallels is indicated by latitude

  • LATitude → LAT=LAP= horizontal

    • Your LAP is horizontal. So latitude is horizontal.

Latitude

Latitude is a measure of the location of a place on the earth's surface, expressed in degrees north or south of the equator. The equator is the imaginary line that runs around the earth's middle, dividing it into the Northern Hemisphere and the Southern Hemisphere. Latitude is used, along with longitude, to specify the absolute location of a place on the earth's surface.

Latitude is measured in degrees, with the equator being at 0° latitude, the North Pole at 90° north latitude (written as 90° N or +90°), and the South Pole at 90° south latitude (written as 90° S or -90°). The latitude of a place is usually expressed as a single number, ranging from -90° at the South Pole to +90° at the North Pole.

Latitude is important because it determines the distance of a place from the equator, which in turn affects its climate, vegetation, and other characteristics. Latitude is also used in navigation, as it can be used to determine the position of a place relative to the equator and the North Pole.

  • Meridian: arcs drawn from the North pole to the South pole

    • Location of meridians is indicated by longitude

Meridian

meridian is an imaginary line on the earth's surface that runs from the North Pole to the South Pole. It is used to measure longitude, which is the distance of a place east or west of the Prime Meridian. The Prime Meridian is an arbitrary reference point that has been established as the starting point for measuring longitude, and it is defined as 0° longitude.

Meridians are spaced evenly around the earth, with each meridian being about 69 miles (111 kilometers) apart at the equator. There are a total of 360 meridians, representing the 360 degrees of longitude. The International Date Line, which roughly follows a 180° longitude, is the meridian that marks the transition between one day and the next.

Meridians are important because they are used to determine the longitude of a place and its time zone. They are also used in navigation, as they can be used to determine the position of a place relative to the Prime Meridian.

  • LONGitude → LONG= up and down

    • If something is long, it is vertical. So longitude is vertical.

Longitude

Longitude is a measure of the location of a place on the earth's surface, expressed in degrees east or west of the Prime Meridian. The Prime Meridian is an imaginary line that runs from the North Pole to the South Pole, passing through the Royal Observatory in Greenwich, England. Longitude is used, along with latitude, to specify the absolute location of a place on the earth's surface.

Longitude is measured in degrees, with the Prime Meridian being at 0° longitude, and the International Date Line, which roughly follows a 180° longitude, being at 180° longitude (written as 180° E or 180° W). The longitude of a place is usually expressed as a single number, ranging from -180° at the International Date Line to +180° at the Prime Meridian.

Longitude is important because it determines the distance of a place from the Prime Meridian, which in turn affects its time zone and the length of its day. Longitude is also used in navigation, as it can be used to determine the position of a place relative to the Prime Meridian.

Peters Projection: The Peters Projection is a cylindrical map projection that presents spatial relationships in a way that maintains area accuracy, making it easier to compare the size of different landmasses. Unlike traditional projections like the Mercator, which distort size for the sake of shape, the Peters Projection aims to provide a more equitable representation of the world's continents and countries, emphasizing their actual sizes relative to one another.

Projection: Projection refers to the method used to represent the curved surface of the Earth on a flat map. This process involves transforming geographic coordinates into a two-dimensional format, which inevitably introduces some distortion in terms of area, shape, distance, or direction. Different projection techniques are employed based on the purpose of the map and the specific data being represented.

Ratio: A ratio is a quantitative relationship between two numbers, showing how many times one value contains or is contained within the other. In the context of maps, a ratio helps represent the scale of the map, allowing users to understand the relationship between distances on the map and actual distances on the ground. Ratios are often expressed in two forms: as a fraction (e.g., 1:100,000) or as a statement (e.g., 'one centimeter represents one kilometer').

Robinson Projection: The Robinson Projection is a map projection designed to create a visually appealing representation of the Earth, balancing size and shape distortions. It is used primarily for world maps, offering a compromise between different projection methods by minimizing distortion in all aspects rather than completely eliminating it. This projection is particularly significant for understanding how the Earth's continents and oceans relate to one another spatially.

Written Scale: A written scale is a method of representing the relationship between distances on a map and actual distances on the ground, typically expressed as a statement, such as '1 inch equals 1 mile'. This type of scale is crucial for interpreting maps accurately, as it provides a clear and straightforward way to understand how measurements on the map relate to real-world distances.

Here is an example of how GPS works:

Imagine that you are lost in a city and you want to find your way back to your hotel. You can use a GPS-enabled device, such as a smartphone or a portable GPS unit, to help you navigate. The device will use GPS signals from satellites orbiting the Earth to calculate your precise location, and then it will provide you with turn-by-turn directions to your destination.

To get started, you would simply enter the address of your hotel into the GPS device, and then it will give you a list of directions to follow. For example, it might tell you to turn left at the next intersection, or to take the next exit off the highway. As you follow the directions, the GPS device will continuously update your location and provide you with updated directions, so you can be sure you are always on the right track.

GIS

GIS (Geographic Information System) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data.

Diffusion

Diffusion is the process by which a concept, practice, or innovation spreads from one place or group to another. 

Geographers document the location where a characteristic develops and track it as it is carried everywhere over time. Characteristics can include clothing styles, diseases, music, and innovative technology. 

Two Types of Diffusion

Relocation diffusion: an idea or innovation spreads through the movement of people from one place to another. This can occur through various forms of migration, such as voluntary migration (e.g. moving for a job or to be with family), forced migration (e.g. as refugees or slaves), and colonization (e.g. the spread of European cultures and languages to the Americas). It can lead to the spread of cultural practices, languages, religions, and other ideas and innovations. For example, the spread of Christianity throughout the world has often occurred through the movement of missionaries and the establishment of new churches in different places. Similarly, the spread of fast food restaurants and coffee shops around the world can be seen as an example of relocation diffusion, as these businesses often expand to new locations through the movement of people and the establishment of new franchises.

Expansion diffusion: a characteristic spreads from one place to another, and each place develops it a little more and adds its unique touch 

Patterns of Diffusion

Here are some examples of expansion diffusion:

  1. The spread of Christianity throughout the world has often occurred through the movement of missionaries and the establishment of new churches in different places.

  2. The spread of the English language has often occurred through the expansion and colonization of English-speaking countries, such as the United States, Canada, and Australia.

  3. The spread of fast food restaurants and coffee shops around the world can be seen as an example of expansion diffusion, as these businesses often expand to new locations through the movement of people and the establishment of new franchises.

  4. The spread of Western-style democracy and capitalism to other countries has often occurred through the expansion and influence of Western powers.

  5. The spread of cultural practices, such as holidays and festivals, can also be seen as an example of expansion diffusion, as people bring these traditions with them when they migrate to new places.

Types of Expansion Diffusion

Hierarchical diffusion: spread of an idea or innovation from one central place or group to surrounding places or groups

One example of hierarchical diffusion is the influence of the Kardashians on popular culture. The Kardashians, as a central, influential source, have helped to spread various trends and ideas through their large social media following and the widespread coverage of their lives in the media. These trends and ideas have then diffused to surrounding places and groups through imitation and adoption. For example, the Kardashians have been credited with popularizing various fashion trends, such as contouring makeup, waist trainers, and oversized sunglasses. They have also helped to spread the idea of "selfie culture," as they often share highly curated and edited photos of themselves on social media. These ideas and trends have then diffused to surrounding places and groups, as people follow and imitate the Kardashians in an effort to be fashionable and on trend.

Contagious diffusion: quick, widespread diffusion of a characteristic throughout the population. Social classes do not matter

Some examples of contagious diffusion include:

  • The spread of a virus or disease through a population. For example, the COVID-19 pandemic has spread rapidly across the world through contagious diffusion.

  • The spread of a new technology or social media platform. For example, the rapid adoption of smartphones and apps like TikTok in recent years can be seen as an example of contagious diffusion.

  • The spread of a trend or fad. For example, the "Ice Bucket Challenge" that went viral on social media a few years ago can be considered an example of contagious diffusion.

  • The spread of a meme or joke. For example, the "OK Boomer" meme spread quickly on social media and became a catchphrase used by younger generations to mock or dismiss the attitudes of older people.

  • The spread of a protest or political movement. For example, the Black Lives Matter movement has spread quickly through social media and has inspired protests and activism around the world.

Stimulus diffusion: the main idea is diffused, but slight changes are made

The expansion of McDonald's to India could be considered an example of stimulus diffusion. In this case, the central, influential source is McDonald's, a fast food chain that originated in the United States. As McDonald's expanded to India, it encountered a new culture with different tastes and preferences. In order to be successful in this new market, McDonald's had to adapt and modify its menu to appeal to Indian consumers. For example, McDonald's in India offers a range of menu items that cater to local tastes, such as chicken and vegetable burgers made with spicy Indian sauces, as well as traditional Indian dishes like chicken tikka and paneer wraps. In this way, McDonald's has diffused its concept of fast food to India, while also being influenced by and adapting to local tastes and preferences. This is an example of stimulus diffusion, as the original idea (fast food) has spread and been modified in the process.

Time and Distance Decay: Time and Distance Decay is the principle that suggests the influence of a phenomenon decreases as it moves farther away from its source, both in terms of time and geographical distance. This concept helps explain how cultural, economic, and social interactions diminish over space and time, impacting patterns of communication, trade, and migration.

Types of Resources on Earth

Renewable resource

These are quickly produced in nature with an unlimited supply.

Examples of renewable resources include:

  • Solar energy: Solar energy is a renewable resource because it is generated from the sun, which is a virtually limitless source of energy.

  • Wind energy: Wind energy is also a renewable resource because it is generated from the wind, which is powered by the sun.

  • Hydroelectric energy: Hydroelectric energy is generated by harnessing the power of moving water, such as from rivers or tides. This is a renewable resource because water is constantly being replenished through the water cycle.

  • Geothermal energy: Geothermal energy is generated by tapping into the Earth's internal heat, which is generated by the decay of radioactive elements. This is a renewable resource because the Earth's internal heat is a constant source of energy.

  • Biomass energy: Biomass energy is generated by burning organic matter, such as wood or plant material. This is a renewable resource because plants can be regrown or replanted after they are harvested.

Nonrenewable resource

These are slowly produced in nature and humans can run out of it.

Examples of nonrenewable resources include:

  • Fossil fuels: Fossil fuels are nonrenewable resources because they are formed from the remains of plants and animals that lived millions of years ago. Once these fuels are used up, they cannot be replenished.

  • Nuclear energy: Nuclear energy is generated by splitting atoms, a process that releases a large amount of energy. However, this energy source is nonrenewable because it relies on the limited supply of uranium and other radioactive elements.

  • Minerals: Many minerals, such as gold and diamonds, are nonrenewable resources because they are formed over millions of years and cannot be replaced once they are extracted from the ground.

  • Water: While water is a renewable resource in the sense that it is constantly being replenished through the water cycle, it can be considered a nonrenewable resource in certain areas where it is scarce and not replenished quickly enough to meet the demand.

Sustainability

To make sure we do not run out of the resources we depend on, humans incorporate sustainabilitySustainability is the ability to maintain or preserve something over time. In the context of the environment, sustainability refers to the ability to use natural resources in a way that does not deplete or damage them, so that they can be used by future generations. This includes recycling, decreasing pollution, planting trees….

The United Nations identified three pillars of sustainability as part of the Brundtland Commission's report, "Our Common Future," published in 1987. These pillars are:

  1. Environmental sustainability: This refers to the ability to use natural resources in a way that does not deplete or damage them, so that they can be used by future generations.

  2. Economic sustainability: This refers to the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs. This involves finding ways to balance economic development and environmental protection.

  3. Social sustainability: This refers to the ability to create and maintain a healthy, inclusive, and just society. This involves finding ways to promote social well-being and equity, and to address issues such as poverty, inequality, and discrimination.

The three pillars of sustainability are often referred to as the "triple bottom line," as they represent a holistic approach to sustainability that takes into account the economic, social, and environmental impacts of human actions.

Humans and the Environment

Human beings are a part of the natural environment, and our actions can have both positive and negative impacts on the environment.

On the positive side, human beings have developed a wide range of technologies, practices, and systems that have allowed us to live longer, healthier lives and to improve the standard of living for many people around the world. These advances have been made possible in part through the use of natural resources, such as oil, gas, and minerals.

However, human activities can also have negative impacts on the environment. The extraction and use of these natural resources can cause pollution, habitat destruction, and other environmental problems. In addition, the increasing population and consumption of resources by humans is putting pressure on the Earth's natural systems and contributing to climate change.

To address these challenges, it is important for humans to find ways to use natural resources in a more sustainable manner, and to reduce the negative impacts of our activities on the environment. This can involve adopting more efficient technologies, conserving resources, and finding ways to reduce waste and pollution. It can also involve working to protect and preserve natural habitats and biodiversity.

The Environment

Pioneering German geographers believed the natural environment shapes the development of our societies. This idea is called environmental determinism. To understand this Human-Environment relationship, the science of the Earth has to be understood. 

An abiotic system is the nonliving or inorganic matter. Earth has four abiotic systems that we interact with: the atmosphere, the lithosphere, the hydrosphere, and the geosphere.

  1. The atmosphere is the layer of gases that surrounds the Earth. It is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases, such as carbon dioxide and water vapor. The atmosphere plays a vital role in regulating the Earth's climate and weather, and it protects the planet from the sun's harmful ultraviolet radiation.

  2. The lithosphere is the solid outer layer of the Earth, which includes the crust and the upper mantle. It is made up of rocks and minerals, and it is the source of many natural resources, such as minerals, oil, and natural gas.

  3. The hydrosphere is the Earth's water system, which includes all the water on the planet, such as oceans, lakes, rivers, and groundwater. The hydrosphere plays a vital role in the Earth's water cycle and climate.

  4. The geosphere is the Earth's solid inner layer, which includes the mantle and the core. It is made up of rocks and minerals, and it is the source of energy for many natural processes, such as earthquakes and volcanic eruptions.

Long ago, the four nations lived together in harmony. Then everything changed when the Fire Nation attacked. 

Well, we are missing fire, but we have the three elements and the biosphere. Each one provides for the biosphere and provides for the organisms. 

The Humans

We have manipulated those abiotic systems and use them to support ourselves. Here’s how:

Hydrosphere: provides all of the water humans and other organisms need

Some examples include:

  1. Building dams to control the flow of water in rivers and streams, which can be used to generate electricity, irrigate crops, and prevent flooding.

  2. Diverting water from one place to another through canals, pipelines, and aqueducts, which allows us to use water in areas where it is scarce.

  3. Extracting groundwater through wells, which allows us to access fresh water for drinking, irrigation, and other purposes.

  4. Treating and purifying water to make it safe for human consumption and other uses.

  5. Monitoring and managing water quality to ensure that it is safe and suitable for different uses.

  6. Developing technologies and infrastructure for storing, distributing, and using water efficiently.

Lithosphere: most plants and animals live and obtain food and shelter

Some examples include:

  1. Quarrying, mining, and drilling to extract minerals, metals, and other resources from the Earth's crust.

  2. Building roads, bridges, and other infrastructure by paving or constructing with concrete, asphalt, and other materials derived from the lithosphere.

  3. Using the Earth's surface as a foundation for buildings, houses, and other structures.

  4. Growing crops and raising animals by modifying the land and soil to create agricultural fields and pastures.

  5. Changing the shape of the land through activities such as deforestation, clear-cutting, and urbanization.

  6. Using the Earth's crust as a source of geothermal energy through activities such as drilling geothermal wells.

  7. Protecting and conserving the Earth's natural resources through sustainable land use practices.

Atmosphere: provides oxygen and protects us against the Sun’s ray

Some examples include:

  1. Burning fossil fuels such as coal, oil, and natural gas, which releases carbon dioxide and other gases into the atmosphere and contributes to climate change.

  2. Planting trees and vegetation, which absorb carbon dioxide from the atmosphere and help mitigate the effects of climate change.

  3. Using technology to monitor and measure atmospheric conditions, such as weather forecasting and air quality monitoring.

  4. Developing technologies to protect ourselves from the elements, such as air conditioning and heating systems.

  5. Using the atmosphere as a means of transportation through activities such as flying in airplanes.

  6. Using the atmosphere as a means of communication through activities such as broadcasting radio and television signals.

  7. Using the atmosphere as a disposal mechanism for waste products, such as releasing pollutants into the air.

Biosphere: interrelated environment, we consume and depend on byproducts from other animals

Some examples include:

  1. Domestication of plants and animals for food, clothing, and other purposes.

  2. Modification of plant and animal genetics through selective breeding and genetic engineering in order to create crops and animals with desired traits.

  3. Use of chemicals and other substances to control pests, weeds, and diseases in agriculture, forestry, and other sectors.

  4. Developing and using technologies to monitor and protect biodiversity, such as conservation programs and protected areas.

  5. Using biotechnology and bioremediation to clean up environmental pollution and restore damaged ecosystems.

  6. Using living organisms as sources of medicine, such as plants used in traditional medicine and microorganisms used in the production of pharmaceuticals.

  7. Using living organisms as sources of industrial products, such as microorganisms used in the production of biofuels and enzymes.

Scales of Analysis in Human Geography

What Are Scales of Analysis and Why are they Important?

Scales of analysis refer to the level or perspective at which a problem or issue is studied or addressed. In other words, they are the "lens" through which we view and understand the world around us. The scale of analysis can range from the global or planetary level, to the regional or national level, to the local or community level, to the individual level.

Different scales of analysis may be appropriate for different types of problems or issues. For example, issues related to global climate change may require a global scale of analysis, while issues related to a particular community or neighborhood may require a local scale of analysis.

Understanding the scale of analysis is important because it can affect the way we approach and solve problems, as well as the types of data and information we need to consider. It can also help us to identify the appropriate level of intervention or action needed to address a particular issue.

What are Map and Cartographic Scales?

Map scale refers to the relationship between the size of an object or feature on a map and its actual size on the ground. It is typically represented as a ratio, such as 1:24,000, or as a fraction, such as 1/24,000.

For example, a map with a scale of 1:24,000 means that one unit of measurement on the map, such as an inch or a centimeter, represents 24,000 of the same units on the ground. This means that if you measure a distance on the map and then compare it to the same distance on the ground, the distance on the ground will be 24,000 times larger.

Map scale is an important consideration when using maps because it determines the level of detail and the area that can be shown on a map. Maps with small scales, such as 1:1,000,000, can show a large area but with less detail, while maps with large scales, such as 1:24,000, can show a small area with more detail.

Cartographic scale refers to the relationship between the size of the features on a map and their actual size in the real world. It determines how much detail can be shown on a map and how much of the area being mapped is shown on the map. There are several different types of map scales, including verbal scales, bar scales, and representative fraction scales. The choice of scale depends on the purpose of the map, the area being mapped, and the intended audience.

Watch this video review on Scales of Analysis in Unit 1

Four Types of Scales of Analysis

The 4 most common types of scales of analysis in AP Human Geography are local, national, regional, & global.

Local (Ex: City with supermarkets highlighted)

The local scale of analysis refers to the level of a particular community or neighborhood. It is a relatively small scale that focuses on issues and problems that affect a specific place or group of people.

At the local scale, issues and problems may be related to the physical environment, such as access to clean water and air, or to social and economic factors, such as poverty, crime, and education.

Examples of issues that might be studied at the local scale include:

  • Environmental impacts of a proposed development or land use change in a particular community

  • Access to health care services in a particular neighborhood

  • Crime rates and public safety in a particular area

  • Quality of schools and educational opportunities in a particular community

Solving problems at the local scale often requires the participation and engagement of the community, as well as the involvement of local government and other stakeholders.

National (Ex: A country color coded based on religion)

The national analysis scale describes the level of a specific country or nation. It operates on a larger scale than local government and focuses on problems and issues that affect the entire country or a substantial portion of it.

Issues and problems on a national scale may be related to the economy, political system, infrastructure, and other factors that shape the country's overall functioning and well-being.

A few examples of issues that can be studied at the national scale include:

  • Economic policies and their impact on different sectors of the economy

  • National security and defense issues

  • Healthcare policy and access to healthcare services

  • Environmental regulations and their impact on the environment and industries

  • Education policy and access to educational opportunities

Finding solutions to problems on a national scale frequently necessitates the participation of national level government agencies, as well as other stakeholders such as businesses, non-profit organizations, and international organizations.

Regional (Ex: Map of schools across a state)

The term "regional scale of analysis" describes a level of a specific region or geographical area that is larger than a single community or neighborhood but smaller than the entire nation. It can range in scale from a few nearby cities to an entire state or province.

The physical environment, such as access to resources and transportation, as well as social and economic factors, like economic growth and cultural identity, may be the source of issues and problems at the regional level.

Some examples of issues that might be studied at the regional scale include:

Multiple levels of government, as well as other stakeholders like businesses, non-profit organizations, and community groups, are frequently involved in regional problem-solving.

Global (Ex: World Map of COVID-19 Cases by variant)

The level of the entire planet, as well as the global scale of systems and processes, is referred to as the global scale of analysis. It includes issues and problems that have a global or regional impact.

The physical environment, such as climate change and biodiversity loss, or social and economic factors, such as global inequality and global governance, may be the source of issues and problems at the global level.

Examples of issues that can be observed at the global scale include:

  • Climate change and its impacts on the environment and society- Loss of biodiversity and the impacts on ecosystems- Global economic inequality and poverty- Global governance and international relations- Access to healthcare, education, and other services in developing countries

The involvement of international organizations, as well as that of national governments, corporations, nonprofits, and other stakeholders, is frequently necessary to address problems on a global scale.

It is IMPORTANT to note: The size of the place (city vs country) and area of interest (religion, supermarket, schools) are various dimensions and scales of analysis. Maps can be created at many different scales, and the appropriate scale depends on the purpose of the map and the area being mapped. For example, a map of the entire world would typically be created at a smaller scale than a map of a single city, because the area being mapped is much larger. Similarly, a map that is focused on a specific theme or subject, such as religion or supermarkets, would be created at a different scale than a map that is intended to show a broader range of information.

What Do Scales of Analysis Reveal?

Scales of analysis reveal the different levels at which problems or issues can be studied and understood. Different scales of analysis provide different perspectives and levels of detail, and can highlight different aspects of a problem or issue.

For example, studying a problem at the global scale may reveal larger patterns and trends that may not be apparent at a smaller scale, while studying a problem at the local scale may reveal the specific ways in which the problem is affecting a particular community or neighborhood.

Using multiple scales of analysis can also help to identify the root causes of a problem and the most effective ways to address it. For example, a problem that is being studied at the local scale may have root causes that are rooted in national or global level policies or processes, and therefore may require intervention at those levels in order to be effectively solved.

Here are some questions for context: 

  • Does a map of bitcoin servers in Italy tell us about bitcoin servers in Australia? No, a map of bitcoin servers in Italy would not provide any information about bitcoin servers in Australia. Bitcoin servers, also known as nodes, are distributed across the world and there is no central organization that maintains a comprehensive list of all of the nodes that exist. In order to get a sense of the distribution of bitcoin nodes in a particular region, you would need to gather data about the nodes that are present in that region.

  • Does a map of poverty in your city reveal trends of poverty in your state? It is possible that a map of poverty in a city could reveal trends of poverty in the state in which the city is located. However, it is important to consider that poverty can vary significantly from one location to another, even within the same state. In order to fully understand the distribution and trends of poverty in a state, it would be necessary to analyze data from across the state, rather than just from one city. This could include data from a variety of sources, such as the Census Bureau, local government agencies, and non-profit organizations.

For example, a regional analysis of economic patterns might involve creating maps of income or employment data at the city or county level, while a regional analysis of physical characteristics might involve creating maps of elevation or land cover at the state or country level.

What is Regional Analysis Used For?

Regional analysis can be used for a wide range of purposes, including planning, policy making, and decision making. It is a useful tool for understanding the unique characteristics and patterns of a specific region and for identifying opportunities and challenges in that region.

It is IMPORTANT to note that regions can be recognized on a global, national, or local level. 

Toponyms

Toponyms are place names. They can be the names of countries, states, cities, streets, and other geographical locations. The study of toponyms is called toponymy. Toponyms can be derived from a variety of sources, including the names of indigenous peoples, the names of colonists or settlers, the names of geographical features, and the names of historical or cultural events. Some toponyms are descriptive and reflect the physical or historical characteristics of a place, while others are more arbitrary and have no particular meaning.

Here are a few examples of toponyms:

  • New York City - named after the Duke of York, who later became King James II of England

  • Mount Everest - named after Sir George Everest, the British Surveyor General of India

  • Rio de Janeiro - Portuguese for "River of January," named by Portuguese explorers who discovered the bay on New Year's Day in 1502

  • Tokyo - derived from the Japanese words "tō" (meaning "east") and "kyō" (meaning "capital")

  • Istanbul - formerly known as Byzantium and Constantinople, named after Emperor Constantine the Great

  • Afghanistan - derived from the Sanskrit word "avagāna," meaning "land of the Afghans"

Site

In human geography, the term "site" is often used to refer to the specific location of a settlement or other human activity. The physical characteristics of a site, such as its topography, climate, and natural resources, can influence the way in which people use and develop the area. For example, a site with a favorable climate and access to water resources may be more attractive for human settlement than a site with a harsh climate and limited resources.

The concept of site can also be used to refer to the cultural, social, and economic factors that shape and are shaped by the location of a settlement or activity. For example, the site of a major city might be influenced by its proximity to transportation networks, its access to natural resources, and its cultural and historical significance. The site of a factory or other industrial facility might be influenced by its proximity to raw materials, transportation, and labor.

Here is an example of site:

  • The site of a hydroelectric dam might be a narrow valley with a fast-flowing river, steep cliffs, and access to a road network. The physical characteristics of the site, such as the river and cliffs, are important for the construction and operation of the dam, as they provide the necessary water flow and support for the dam structure. The access to a road network is also important for transporting materials and equipment to the site.

Situation

In human geography, the term "situation" refers to the location of a place or phenomenon in relation to its surroundings. It can include both the physical characteristics of a place, such as its topography, climate, and natural resources, as well as the cultural, social, and economic factors that shape and are shaped by its location.

The situation of a place can influence its function and the way in which it is used. For example, the situation of a city on a major river might make it an important transportation hub, while the situation of a city in a mountainous region might make it a center for tourism. The situation of a place can also be shaped by its history and culture, as well as by larger political and economic forces.

Here is an example of situation:

  • The situation of a small village might be in a remote, mountainous region with limited access to transportation and few natural resources. The village might be isolated from major urban centers and have a limited economy based on subsistence farming and forestry. The situation of the village, in a remote and resource-poor region, might influence its development and the way of life of its residents. On the other hand, the village's situation in a mountainous region might also offer opportunities for tourism and outdoor recreation.

The concept of situation is often used in combination with the concept of site to understand the complex factors that influence the location and development of human settlements and activities.

Formal Region

A formal region is a geographical area that is defined by a specific characteristic or set of characteristics that are uniform across the region. Formal regions are often based on physical or cultural features that are easily identifiable and can be clearly defined.

Examples of formal regions include:

  • Political regions, such as countries, states, and provinces, which are defined by administrative boundaries

  • Statistical regions, such as census tracts, which are defined by specific demographic or economic data

  • Climatic regions, such as the Köppen climate classification system, which are defined by temperature and precipitation patterns

  • Vegetation regions, such as ecoregions, which are defined by the type and distribution of plant life

  • Cultural regions, such as language regions or dialect areas, which are defined by shared cultural characteristics such as language or customs.

Formal regions are often used as a way to organize and study geographical phenomena and to understand patterns and trends within a specific area.

Functional Region

A functional region is a geographical area that is defined by the flow of goods, services, information, or other resources between the places within the region. Unlike a formal region, which is defined by a specific characteristic that is uniform across the region, a functional region is defined by the relationships and connections between the places within the region.

Examples of functional regions include:

  • Economic regions, such as a metropolitan area or a trade region, which are defined by the flow of goods, services, and economic activity between the places within the region

  • Transportation regions, such as a travel shed or a commuting zone, which are defined by the flow of people or goods between the places within the region

  • Communication regions, such as a media market or a news region, which are defined by the flow of information between the places within the region

Functional regions can be thought of as networks or systems, with the places within the region connected by the flows of goods, services, information, or other resources. The concept of a functional region is often used in economic and transportation planning, as well as in the study of social and cultural phenomena.

Vernacular Region

A vernacular region, also known as a perceptual region or a folk region, is a geographical area that is defined by the common perceptions, experiences, and cultural identity of the people who live within the region. Vernacular regions are not based on objective, measurable characteristics, but rather on the subjective experiences and cultural meanings of the people who live within the region.

Vernacular regions often have a strong sense of regional identity and may be marked by distinctive cultural traditions, customs, and ways of life. They can be based on a variety of factors, including geography, history, language, ethnicity, and shared cultural experiences.

Examples of vernacular regions include:

  • The American South, which is often defined by its distinctive culture, history, and way of life

  • The Rust Belt, a region in the northeastern and midwestern United States that is defined by its industrial history and economic decline

  • The Bible Belt, a region in the southern United States that is known for its strong religious traditions

The concept of a vernacular region is often used in cultural geography and the study of regional identity.

Review

Toponym: name given to a place on Earth

  • Ex: “The house of 653 Trechdell Dr.”

Site: physical character of a place (climate, water sources, vegetation)

  • Ex: On a hill, fertile garden, near a river

Situation: location of a place relative to other places

  • Ex: “My house is next to the YMCA and Tusculum Elementary.”

Formal region: area where everyone shares one unique characteristic

  • Ex: The characteristic can be a common language, climate, political party

Functional region: area organized around a hub

  • Ex: The hub can be the center of the city that attracts people

  • Ex: Downtown is the hub of most cities

  • Ex: TV stations have a main hub where all signals are emitted

Vernacular region: area that emerges from a sense of place, people believe the area exists because of culture

  • Ex: Southern USA is a vernacular region

  • Ex: People have different definitions of the South including which states are “in the South”

  • Ex: Definitions are within the same general area

Formal Region: A formal region is an area defined by specific, measurable characteristics that are consistent throughout the space. These regions are often marked by uniformity in one or more physical or cultural traits, such as language, climate, or economic activity. Understanding formal regions helps to categorize and analyze various aspects of geography, allowing for clearer regional analysis.

Functional Region: A functional region is a geographic area defined by a specific set of activities or interactions that occur within it, often centered around a node or focal point. This type of region is characterized by the connections and relationships between places, with the center often serving as the hub for services or economic activities that influence the surrounding areas. Understanding functional regions helps in analyzing how different areas interact and the effects of those interactions on local and regional development.

Region Types: Region types refer to the different categories used to classify areas of the Earth based on various criteria such as physical characteristics, cultural traits, and economic activities. Understanding region types is crucial in regional analysis as it helps geographers and researchers identify patterns, make comparisons, and draw conclusions about spatial relationships across different areas.

Regional Analysis: Regional analysis refers to the examination and interpretation of geographic regions by considering their physical, cultural, economic, and political characteristics. This method allows for a comprehensive understanding of how different areas are interconnected and how specific attributes define them, influencing human activity and societal development.

Site: Site refers to the specific physical characteristics and location of a place, including its natural features, resources, and built environment. This concept helps in understanding how the unique attributes of a location influence human activities, settlement patterns, and regional dynamics. By examining site, one can evaluate how environmental factors shape social and economic interactions within an area.

Situation: Situation refers to the location of a place relative to other places and its surrounding environment, including its accessibility and connections to larger networks. Understanding situation helps to analyze how geographic factors influence the interactions and relationships between different locations, as well as the economic, social, and cultural dynamics that arise from those interactions.

Toponyms: Toponyms are the names given to specific places or geographic features, reflecting cultural, historical, and linguistic contexts. They serve as critical identifiers of locations, offering insights into the cultural landscapes they belong to and the regions they represent. By studying toponyms, one can understand how geography and culture interact, providing a window into human experiences and societal values.

Vernacular Region: A vernacular region is a place that people believe exists as part of their cultural identity, often defined by informal and subjective criteria rather than strict geographic boundaries. This type of region is shaped by people's perceptions, experiences, and cultural practices, making it essential for understanding how individuals relate to their environment and each other.
