TOPOGRAPHIC MAPPING

Professional stereo collection remains the most accurate method for line mapping and topographic vector data collection, far more so than simply mapping from orthophoto. Measurements can be made with an accuracy of a few centimetres in height and position.

Our firm maintains seven workstations for this task and is able to handle large or small projects with this capacity.

Topographic survey is simply the recording of coordinates and height data for a particular survey area. This data can be used to create spot height maps, contour maps, or more complex terrain models of the surveyed area.
