Abstract

Quantfying landscape changes comparing 1850 and 2010 DEM
Track: Lidar and 3D Mapping
Authors: Mogens Greve, Mette Greve

We are rectifying legacy topography maps dating back to 1843-1887. For the largest raised bog in Denmark, we have digitized the elevations and created a mid 19th century DEM. This DEM has been compared to a Lidar derived national DEM created in 2010 and the compression or mining of the peatlands have been evaluated.
