Topographic Map Skills:

Area and Grid Reference

Learning Intentions

By the end of the lesson, you should be able to:

Demonstrate how to find a feature using area reference
Pinpoint the location of a feature using grid reference
Determine the scale of a photograph by comparing to a topographic map

Topographic maps are detailed representations of the Earth's surface, showing natural and man-made features. They use contour lines to depict elevation and the shape of the terrain, such as hills, valleys, and mountains. These maps also include features like rivers, roads, and buildings.

Topographic maps are essential for various activities, including hiking, planning, and engineering. They help users understand the landscape's physical characteristics, navigate challenging terrains, and plan construction projects.

By providing a clear picture of the terrain, topographic maps are invaluable tools for outdoor enthusiasts, geographers, and professionals in land use planning.

Area and grid references help users accurately locate features on a topographic map, such as a specific hill, building, or river.

Area and Grid References on a Topographic Map:

Area references use four digits to identify a general area on a map. The first two digits (eastings) represent the horizontal position, and the last two digits (northings) represent the vertical position.

For example, an area reference of 1234 indicates a square where the bottom-left corner is at easting 12 and northing 34.

Grid references provide a more precise location using six digits.

The first three digits (eastings) and the last three digits (northings) pinpoint an exact location within the area square.

For example, a grid reference of 123456 indicates a specific point within the square identified by the area reference 1234.
