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 resolutionThe 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 resolutionThe 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 resolutionThe 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 …
