In conjunction with Aquatonics, Merrett Survey's have made innovative use of terrestrial laser scanning for biotope mapping. The laser scanning allows biologists to define complex biotope boundaries to a very high accuracy. We can create cross sections to measure the height of the vegetation and create highly accurate Digital Terrain Models for very detailed geomorphological analysis. Digital Terrain Models accurately represent landform surface variability and provide an effective means to monitor morphological change.

Terrestrial laser scan data can therefore be used as an effective monitoring and management tool for flood plain mapping. The main advantages of terrestrial laser scanning over alternatives such as airborne LiDAR or photogrammetry are increased accuracy of the data and smaller costs.
