Unit 1 Spatial Geography
Types of Maps in Human Geography
Reference Maps:
Informational maps that show boundaries and place names.
Examples: World map, city map, topographical maps, subway maps, theme park maps.
Helps identify specific locations.
Thematic Maps:
Tell a story through the representation of data (density & distribution).
Types of Geospatial Data Mapping:
Choropleth Maps:
Use colors/shading to show quantifiable data.
Darker colors represent higher density.
Example: COVID-19 case distribution by state.
Dot Maps:
Each dot represents a value in its approximate location.
Shows spatial distribution of a phenomenon.
Example: Population density in an area.
Graduated Symbol Maps:
Symbols vary in size according to value (proportional).
Denser areas have larger symbols.
Isoline Maps:
Connect areas of equal values with lines.
Common in weather maps; can be hard to interpret without color.
Cartograms:
Distort land area to represent value (e.g., population).
Data Analysis in Geography
Measuring Location, Distance, and Direction:
Absolute: Quantitative measures (e.g., distance of 1221 miles from Nashville to New York).
Relative: Qualitative measures (e.g., "my house is near the beach").
Types of Patterns:
Clustered: Grouped or concentrated.
Dispersed: Spread out.
Uniform: Evenly spread.
Random: No discernible pattern.
Map Projections
Importance of Map Projections:
Distort shape, size, distance, and direction when representing spherical Earth on a flat map.
Common Projections:
Mercator Projection: Preserves shape but distorts size at higher latitudes (e.g., Greenland).
Gall-Peters Projection: Preserves area but distorts shape (exaggerates sizes of continents).
Robinson Projection: Compromise projection that balances size and shape but distorts polar areas.
Goodes Projection: Interrupts oceans to maintain size/shape of land masses, used for thematic maps.
Geographic Data Collection
Methods:
Field Studies: Gathering information directly from the environment.
Organizations: Government, private, and academic institutions collect data (e.g., census data).
Technologies:
GIS (Geographic Information Systems): Analyzes, stores, and displays geographic data.
Remote Sensing: Satellite data for urban sprawl, drought effects, etc.
Satellite Navigation Systems: Provides precise location data.
Online Mapping: Various digital resources for geographic analysis.
Cartography: The art and science of map-making, essential for visualizing geographic information and spatial relationships.
Geospatial Analysis: The process of interpreting spatial data to make informed decisions about land use and environmental management.
Spatial Concepts
Definitions:
Absolute Location: Fixed point defined by coordinates (latitude/longitude).
Relative Location: Location in relation to others; significance determined by context.
Place: Unique human experiences tied to characteristics of a location.
Spatial Interaction: Movement and flow of people/information/goods between places.
Distance Decay: Lesser interaction with increased distance; mitigated by technology today.
Time-Space Compression: Technology reduces time and space, increasing connectivity.
Sustainability and Land Use
Sustainability: Actions managing resources for immediate benefits and future preservation (example: biomass energy).
Natural Resources: Renewable vs. nonrenewable resources; essential for human use.
Land Use: Human modification of the earth for agriculture, industry, residential, etc.
Theories of Human-Environmental Interaction
Environmental Determinism: Suggests environment fully shapes human culture; simplistic view.
Possibilism: Acknowledges the environment's role but also human choice and technological adaptation.
Scale Analysis
Importance of Scale: Influences data interpretation and decision-making across various geographical levels.
Types of Regions:
Formal Regions: Defined by unifying characteristics (e.g., language, politics).
Functional Regions: Defined by activity centers or networks (e.g., urban delivery zones).
Perceptual Regions: Subjective and dependent on individual perception; fuzzy boundaries.
Theories of Human-Environmental Interaction
Environmental Determinism: Suggests environment fully shapes human culture; simplistic view.
Possibilism: Acknowledges the environment's role but also human choice and technological adaptation.
Malthusian Theory: Proposed by Thomas Robert Malthus, it suggests that population growth will inevitably outpace food production, leading to famine and resource scarcity.
Neo-Malthusianism: A modern adaptation of Malthusian theory focusing on the relationships between population growth, resource depletion, and environmental degradation, emphasizing sustainable practices.
Anti-Malthusian Perspectives: These reject the notion that population growth will lead to catastrophe, often arguing that innovation and technological advancement can overcome resource limitations.
Spatial Interaction: Movement and flow of people/information/goods between places. Assimilation, Acculturation, and Syncretism are different forms of cultural exchange and interaction:
Assimilation: The process by which a minority group adopts the customs and attitudes of the dominant culture, often losing its original cultural identity.
Acculturation: The process of cultural change and psychological change that results following meeting between cultures, where the minority culture adopts some elements of the dominant culture while preserving its own.
Syncretism: The amalgamation of different religions, cultures, or schools of thought, resulting in new practices and beliefs that combine elements from both sides.
Types of Expansion Diffusion:
Contagious Diffusion: Rapid, widespread diffusion of a feature or trend throughout a population; tends to happen as the disease spreads.
Hierarchical Diffusion: Spread of a feature or trend from one key person or node of authority to other persons or places.
Stimulus Diffusion: The spread of an underlying principle, even though a specific characteristic is rejected; commonly seen in cultural adaptions.
Sustainability: Actions managing resources for immediate benefits and future preservation (example: biomass energy).
Social Pillar: Focuses on social equity, inclusivity, and community well-being. It promotes fairness and quality of life for all individuals, ensuring communities have access to essential services and support.
Economic Pillar: Aims at economic viability and stability while considering sustainable practices. This pillar emphasizes responsible resource management and the need for economic growth that does not degrade the environment.
Natural Resources: Renewable vs. nonrenewable resources; essential for human use.
Land Use: Human modification of the earth for agriculture, industry, residential, etc.
