Topographic Surveys

Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations.

To create maps and mapping surfaces for engineering or architects to use as a base of their work. This work is done with many multiple points, measured in three dimension. Measurement practice can include conventional total station data points, points gathered with field crews equipped with GPS, or point clouds from aerial photometric or lidar technology. Final product can be a simple topographic map with contour interval lines, or a computer-based surface model.
