Explanation of Solution

The difference between a topographic map and a planimetric map is described below:

Topographic map

  • Topographic map shows the earth's surface in 3-D.
  • It represents with contour lines to show the elevation at definite intervals.
  • The contour intervals are decided as per the requirement.
  • The details of the map can be seen precisely by using less contour intervals which increases the duration and cost.

Planimetric Mapping

  • Planimetric map also shows the landscapes 3-D.
  • However, the feathers are denoted with points and lines.
  • The aerial photography is used to take out the landscapes.
  • The information's features can be attached with the map using GIS.
  • Since the features are represented by contours lines, the cost is less compared to the topographic map.
