Commercial DEM Providers
Introduction
This page holds a list of some of the major 3rd party commercial providers of high-resolution and high-quality DEM's. Typically a DEM, DTM or DSM purchased from one of these providers comes with a price-per-square-kilometers price-tag - along with a required minimum purchase area (typically in the order of some hundreds of square kilometers). If data are delivered in a standard GIS format such as geotiff, xyz, surfer-grid or ESRI-shape-files, then the data is easily loaded into the elevation-objects or the line-objecs of windPRO.
Please drop us a line at support@emd.dk if you know of more vendors that you think should be added to the list.
Euro-Maps 3D from GAF-AG
GAF-AG provides a verity of DSM models in resolutions from 0.30m to 5.0m (with the Euro-Maps 3D dataset).
