Topo-Bathymetric LiDAR: The Missing Link in the Dutch National Height Model?

Het Waterschapshuis is responsible for joint efforts of the 21 public water agencies (aka boards) in The Netherlands, which estimate that 26% of the country is below sea level, and another 29% is sensitive to flooding from rivers. Het Waterschapshuis manages the national program for airborne LiDAR collection and since 2012, it has also managed the annual imagery acquisition program, which collects 10cm resolution aerial photography.

The first edition of the Dutch National Elevation Model (AHN) was started in 1997 and was completed in 2004. From 2007-2012, the second edition was completed with very high geospatial standards for that time. AHN3 will be completed in 2019, so the focus of this presentation is on their technical evaluation of three (3) LiDAR sensor technologies to support this critical data acquisition program. The objective of this presentation is to review the results of Het Waterschapshuis’ technical evaluations of single photon, dual wavelength, and bathymetric LiDAR sensors, and their equipment preferences.
