Question

How to find the area in topography

Answer 1

Answer:

Following is an example for finding out area of one grid square on Topographic map:

First find out the scale of the map.

For example, if a topographic map has a scale of 1:50 000. To find out the area, we will have to find the scale.

If the scale of the map in RF is 1:50 000, then each cm represents 0.5km.

Length: 2cm x 0.5km = 1.0 km.

Width: 2cm X 0.5 km = 1.0km.

Area of One Grid Square = 1.0km x 1.0km = 1.0 sq. km

Based on the area of the one grid square km, you will be able to find the area of a topographic map
