Which term describes the dimensional scope of a planimetric map?

• A. Two horizontal dimensions
• B. Three dimensions
• C. Contour lines
• D. Elevation model

Answer: (A)

Planimetric maps record features on the flat plane using two horizontal coordinates, essentially x and y. This means their dimensional scope is two dimensions, confined to the horizontal layout of the terrain. Vertical elevation isn’t part of the planimetric view unless you add separate data. Contour lines convey elevation changes, and an elevation model represents terrain in three dimensions, so they describe vertical dimension rather than the map’s dimensional scope.
