Study Notes
Latitude & Longitude
- Locations on Earth are defined by latitude and longitude, measured in degrees (°).
- Latitude indicates distance north or south from the equator, with the equator at 0° latitude.
- Latitude ranges from 0° at the equator to 90° at the poles (90° N at the North Pole, 90° S at the South Pole).
- Longitude indicates distance east or west from the prime meridian in Greenwich, England, also at 0° longitude.
- Longitude ranges from 0° to 180° east and west of the prime meridian.
Area & Grid Reference
- Eastings are horizontal numbers on a map, increasing towards the east, while northings are vertical numbers, increasing towards the north.
- To find an area reference (AR), write the easting and northing of the lower left corner of a square on the grid, always in the order of easting before northing.
- Area references consist of four digits, formatted as two-digit eastings followed by two-digit northings.
- For precise location identification, grid references are used, dividing eastings and northings into tenths.
- The grid reference combines the three-digit easting with the three-digit northing to form a six-digit reference for a specific point, enhancing map communication and usability.
Relief
- Relief measures the difference in elevation between the highest and lowest points in a landscape, typically noted in meters (m) or feet (ft).
- Common geographical features include mountains (high elevation), valleys, plains, and plateaus (generally lower elevation).
- Landscapes with greater elevation variation are described as high relief, while those with minimal variation are low relief.
- Topographical maps illustrate relief through spot heights (exact elevations) and contour lines (illustrating elevation changes).
- Spot heights mark specific heights above sea level, while contour lines depict the land's shape, with numbers indicating elevation.
- Relief can be calculated by subtracting the lowest elevation point from the highest elevation point in the area.
Scale
- Maps are a scaled-down representation of geographic areas, aiding in spatial understanding and navigation.
