Airbus is coming in hot this month with new satellites and new products. Along with the 30-centimeter resolution Pléiades Neo optical constellation , Airbus updated their 12-meter (m) resolution 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, and 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 early 2022.
