NASA’s Commercial Satellite Data Acquisition (CSDA) Program announces the addition of three digital elevation and digital terrain products from Vantor’s Precision3D Product Line to its Satellite Data Explorer (SDX) data access and discovery tool.
The products include:
Digital Surface Model (DSM) at 1-meter spatial resolution
The DSM is a 3D elevation model derived from imagery captured by Vantor’s constellation of Worldview satellites. It provides precise measurements across all surfaces and terrains and is available in standard formats to facilitate integration into a range of workflows and analysis. It is suitable for a range of applications requiring detailed elevation data, such as urban planning, environmental monitoring, disaster mitigation and response, and terrain mapping.
Digital Terrain Model (DTM) at 1-meter spatial resolution
The DTM is a 3D elevation model derived from the DSM that offers bare-earth elevation data by removing above-ground features like vegetation and buildings and is designed for analyzing terrain and topography. Created with automated processing techniques, the DTM ensures consistency across all terrain types and is available in a variety of in user-friendly formats.
Elevation Bundle (DSM + DTM) at 1-, 2-, and 4-meter spatial resolution
The Elevation Bundle, which combines the DSM and DTM products, provides a detailed view of both above-ground features and the underlying bare earth. With global coverage and high-resolution data at 1-, 2-, and 4-meter resolution, this product offers reliable elevation information in all types of terrain, making it a suitable tool for a range of applications from slope analysis to flood modeling.
“Digital Elevation Models are foundational geospatial infrastructure for NASA’s science community, and including them in the CSDA program ensures broad, consistent access to high‑quality commercial terrain data that sharpen geometric accuracy, support Earth system and hazard modeling, and extend NASA’s capabilities in support of Earth action priorities,” said Dana Ostrenga, Project Manager for the CSDA.
