Abstract:
Currently many Digital Elevation Models (DEMs) are derived from surveys obtained by LiDAR flights. The quality of both products is usually assessed using control point-based techniques. Although it seems that this way of reporting quality is not fully adequate because the superficial nature of both the DEMs and the area covered by the LiDAR survey. For this last reason (the superficial nature of the objects to be controlled), according to the ideas contribution in Geoprocessing we propose to control the quality of the DEMs and LiDAR flights by means of a Terrestrial Laser Scanner (TLS) located on a pole at 6 or 7 m from the ground. We propose a configuration of 4 scan stations registered in a single point cloud and georeferenced, so that its accuracy is greater than the product that is intended to be controlled.
