Towards a Living Elevation Model
Het Waterschapshuis is responsible for joint efforts of the 21 public water agencies (aka boards) in The Netherlands. Het Waterschapshuis manages the national program for airborne LiDAR collection, together with the Ministry of Infrastructure and Water Management and the Provinces. Since 2012, it has also managed the annual imagery acquisition program, which collects 10cm or better 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. We are investigating a living elevation model. Nowadays it’s not only airborne LiDAR that acquires point cloud data. There’s many sensors out there! How can data acquired by these sensor be used to keep AHN up to date?
