The intermediate DEMs feature two different variants: the basic Digital Surface Model (DSM), which includes the heights of all natural and man-made objects, and the DSM hydro, where water body features derived from the radar data are extracted and edited. Five Quality Layers provide information on the data source and the production. These product variants and quality layers will constitute the core WorldDEM™ product offering. In the near future this offering will be complemented by a Digital Terrain Model and additional derived products.
Upon evaluation of the sample data, Astrium invites you to provide feedback on the data quality.
The comments will support the enhancement of the WorldDEM™ offering and services.
