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.

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). The Euro-Maps 3D was a part of DEM-elevation study by EMD presented at the Wind Resource workshop in Brussel 2019 - where the map 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.
