Topographical Surveying

Airborne laser scanning is now becoming a reliable and cost effective technique for topographical surveying. Airborne LiDAR systems have become a dominant method for the acquisition of high-precision DEMs and DTMs.

Overview

The speed of laser scanning easily rivals alternative terrestrial methods such as GPS and total stations.

Using the correct software tools such as TerraScan, vegetation and unwanted features can be quickly and reliably removed from the survey data. Using TerraModeler, DTM's, contour plots, sections and volume calculations can be generated easily.

Suggested Scanners

The Riegl LMS-Q560, and Q280i are typically used for topographical mapping.

Typical Applications

Capture of 3D scan data for mapping of the natural and built environment, including tree canopy extent, golf course design and flood mapping.
