Planimetrics is the study of plane measurements, including angles, distances, and areas.

In geography[edit]

Planimetric elements in geography are those features that are independent of elevation, such as roads, building footprints, and rivers and lakes. They are represented on two-dimensional maps as they are seen from the air, or in aerial photography.[1] These features are often digitized from orthorectified aerial photography into data layers that can be used in analysis and cartographic outputs.[2]

A planimetric map is one that does not include relief data.[3]
