Planimetric Control

A survey in which a sequence of bearing and distance of lines between points on the
ground is obtained from field measurements and used in determining positions of the points. Generally conducted using survey Total Station and Target Prism. Also called control traverse.

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. These features are often digitized from orthorectified aerial photography into data layers that can be used in analysis and cartographic outputs. A planimetric map is one that does not include relief data.

Application: Site Survey, Marine Construction, Civil Construction, Dredging Operations, Harbor Improvement.
