If your next mapping project requires large-area coverage of a seamless digital elevation model (DEM), then it is time to check out Airbus’ updated WorldDEM product! The new version, called WorldDEM Neo, has improved 5-m resolution and is also derived from TerraSAR-X and TanDEM-X radar stereo pairs. However, the radar pairs used to create this 5-m elevation dataset are more recent than its predecessor as they were collected from 2017 to 2021. Currently, WorldDEM Neo is only available as a digital surface model (DSM) – we expect digital terrain model (DTM) sales to start in Q1 2023.
