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.
