Abstract

LiDAR-derived DEMs can take weeks to process, thus minimising the effectiveness of timely solutions. In order to reach realistic processing times, data sets need to be reduced. However, data reduction needs to be conducted with the minimum loss of accuracy. This study investigates the effects of data reduction on LiDAR-derived DEMs.
