Question

3. How do colours represent different relief features on topo sheets?
​

Answer 1

Explanation:

Man made features like settlements, roads and cart track represent red colour on topographical sheets or topographical maps.

The color brown is used to denote most contour lines on a map, which are relief features and elevations. Topographic maps use green to denote vegetation such as woods, while blue is used to denote water features like lakes, swamps, rivers, and drainage.
