WorldDEM ™ NEO |
| Note |
The WorldDEM Neo DSM product is an edited Digital Surface Model based on the combination of the TanDEM-X Change rawDEM data acquired and processed by the German Space
Agency (DLR) and the WorldDEM ™ product.
WorldDEM Neo has been built up on satellite imagery and corresponding interferometric elevation data of the continuing TanDEM-X Mission primarily acquired in the years 2017 to 2021.
An adaptive, weighted combination algorithm to merge the mosaic of Change rawDEM scenes (2017-2021, grid spacing: 0.2 arcseconds) with the edited WorldDEM coverage (2010-2015;
grid spacing: 0.4 arcseconds) has been developed. A fully automated detection and flattening of hydrological features and airports is applied.
The WorldDEM NEO is ~5m grid spacing, with grid spacing of 0.15 arcseconds. |
