Comprehensive Geography and Spatial Concepts Study Guide

Map Projections

• Mercator Map:

  • The most commonly used map projection because the shape of the land is accurate.
  • Primarily utilized for ocean navigation.

• Gall-Peters Map:

  • Features a stretched size appearance that creates an accurate land size representation but results in an incorrect shape.
  • Provides an accurate projection of developing countries, which are usually forgotten or distorted in traditional projections.

• Goode Map:

  • An interrupted map projection, making it bad for navigation.
  • Maintains accurate land size with large land areas relative to oceans, creating spatial distortion.

• Robinson Map:

  • Formatted as an interrupted map, making it bad for navigation.
  • Maintains accurate land size with large land areas in comparison to oceans, which creates spatial distortion.

Geographic Data and Collection Methods

Geographic data encompasses any information used to describe a specific item location, or trend on the Earth's surface.

• Field Observations:

  • The practice of physically going somewhere to collect first-hand data at that specific location.

• Media Reports:

  • Encompasses articles, news broadcasts, and any media reports that geographers use to analyze human interactions with the environment.

• Travel Narratives:

  • Written or recorded accounts of people's experiences while traveling across regions.

• Policy Documents:

  • Official written records that set established rules and guidelines.

• Personal Interviews:

  • Direct communication where someone explains their first-person experience and personal understanding to another individual.

• Landscape Analysis:

  • Refers directly to analyzing the shape of the land.
  • The primary goal is to describe how humans have made an impact on that space.

Geospatial Technologies and Photographic Interpretation

• Photographic Interpretation:

  • The primary goal is to describe how humans have made an impact on a specific space by examining photographic evidence.

• Geospatial Technologies:

  • Geographic Information System (GIS):
  • A computer system designed to store, analyze, and display data connected to specific places on the Earth's surface.
  • Satellite Navigation System:
  • Utilizes Global Positioning System (GPS) receivers on the Earth's surface that use the locations of multiple satellites to determine and record a receiver's exact location.
  • Remote Sensing:
  • The process of gathering data about an object or area from a distance without making physical contact.
  • Online Mapping and Visualization:
  • Websites that provide emphasized graphical and text information in the form of interactive maps and databases.
  • Often designed to assist users with geographic tasks but frequently attempt to sell products or services to the user.

Population Census and Its Power

A census is an official count of the population. In the United States, a national census takes place every $10$ years and is used to make numerous governmental decisions.

• Distribution of Money:

  • Guides the annual allocation of financial resources.
  • Directs funding for essential infrastructure and community needs, specifically roads, schools, and public services.

• Political Power:

  • Determines the exact number of representatives a state receives in Congress.

• Business Applications:

  • Provides strategic demographic and geographic information to businesses to guide decisions regarding where to place facilities.

Spatial Concepts: Location, Latitude, and Longitude

Spatial concepts are the different connections used to describe the relationships between different geographic locations.

• Absolute Location:

  • A precise spot that never changes.
  • Examples include a specific street address or exact latitude and longitude coordinates.

• Latitude:

  • Invisible lines that run horizontally across the globe.
  • Contains a total of $181$ lines.
  • The Equator is positioned at $0^\text{o}$ in the center of the globe.
  • Lines wrap around the entirety of the globe and never intersect with one another.
  • Divided into high, medium, and low categories of latitude.

• Longitude:

  • Invisible lines that run vertically across the globe.
  • Contains a total of $361$ lines.
  • The Prime Meridian is positioned at $0^\text{o}$ in the center of the globe.
  • Lines of longitude do not intersect with other longitude lines, but only intersect with latitude lines.

• Relative Location:

  • Describes a location that is not specific, defined in relation to somewhere else.
  • Relies on spatial vocabulary such as "peripheral", which means outside or on the outer boundary.
