Geography Chapter: Location Determination

Determination of Location of a Place on Earth's Surface

• Absolute Location

  • Defined by specific coordinates using latitude and longitude.
  • Latitude: measures north/south of the Equator (0° to 90°).
  • Longitude: measures east/west of the Prime Meridian (0° to 180°).
  • Example: Paris is located at 48.8566° N, 2.3522° E.

• Relative Location

  • Describes a place in relation to other landmarks or locations.
  • Useful for understanding a place's context.
  • Example: Rome is south of Florence and west of the Adriatic Sea.

• Geographical Coordinates

  • The grid system used to pinpoint locations on the globe.
  • Formed by intersecting lines of latitude (horizontal) and longitude (vertical).

• Map Projections

  • Various methods to represent the curved surface of the earth on flat surfaces.
  • Common types include Mercator, Robinson, and Winkel Tripel.
  • Each projection has advantages and disadvantages in terms of scale, shape, and distance.

• GIS (Geographical Information Systems)

  • Technology used for mapping and analyzing spatial data.
  • Combines map data with various types of information for analysis.
  • Applications include urban planning, resource management, and environmental monitoring.

• Topographic Maps

  • Represent surface features including elevation, terrain, and landforms.
  • Use contour lines to indicate changes in elevation.

• Satellite Imagery

  • Captured by satellites orbiting Earth.
  • Provides real-time data and imagery for analysis and monitoring environmental changes.

• Tools for Determining Location

  • Compass: indicates cardinal directions (N, E, S, W).
  • Global Positioning System (GPS): provides precise location data via satellites.
  • Maps (paper and digital): various types used for navigation and spatial understanding.

• Cultural and Economic Factors

  • Influence human activity and settlement patterns.
  • Resources availability, climate, and topography impact location choices.
