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 per-square-kilometers price-tag - along with a minimum purchase area requirement (typically in the order of some hundreds of square kilometers). Most vendors will deliver data in a standard GIS format such as geotiff, xyz, surfer-grid or ESRI-shape-files; these data are easily loaded into the elevation-objects or the line-objecs of windPRO. WindPRO will smoothly generate height contour lines - if you choose to purchase data in a raster format only.
Please drop us a line at support@emd.dk if you know of more vendors that you think should be added to the list.
List of 3rd Party Commercial DEM Providers
Below a list of commercial providers of DSM's or DEM's.
Euro-Maps 3D from GAF-AG
GAF-AG provides a varity of DSM models in resolutions from 0.30m to 5.0m (with the Euro-Maps 3D dataset). The Euro-Maps 3D was a part of a DEM-quality study by EMD presented at the Wind Resource workshop in Brussel 2019. Here the Euro-Maps 3D model came out with a nice performance on the Norwegian Midtfjellet site (see page 14 in this pdf).

AW3D from NTT-Data and RESTEC
ALOS World 3D (AW3D) is the higher resolution, commercial 'cousin' of the AW3D30 dataset.

WorldDEM from Airbus
World DEM from Airbus is a DEM with global pole-to-pole coverage. It comes with a 12m resolution and its accuracy is specified at 2m (relative) and 4m (absolute). It is possible to purchase both DSM and DTM's from the WorldDEM databases.

DEMs from DHI-GRAS
DHI-Gras is a partner in our joint InnoWind project and is a distributor of many DEM's. As such, DHI-GRAS is able to provide guidance on which DEM is appriate and cost-efficient to use.
