CSDA Vendor - Vantor
NASA has acquired commercial datasets from Vantor (formerly Maxar) for scientific purposes.
Vantor, Inc. (formerly Maxar Intelligence) was one of the vendors selected for evaluation in the original Commercial Satellite Data Acquisition (CSDA) program pilot. CSDA distributes data acquired by the Vantor constellation, including: WorldView-1, WorldView-2, WorldView-3, WorldView-4, GeoEye-1, QuickBird, and IKONOS. The Vantor constellation offers a unique catalog of very-high-resolution data products with resolutions as low as 31 cm per pixel, from the WorldView-3 Panchromatic band.
Authorized Data Use and Users
All members of the U.S. Government and researchers funded by the U.S. Government have access to declassified archived Vantor imagery as well as tasking new acquisitions available through the CSDA program.
Obtaining Data
To request access to CSDA-distributed data, complete the CSDA Authorization form. The CSDA team will verify if the user is authorized for data access. For data not available through the SDX, please use the Data Request Form to initiate a request with the CSDA Data Management Team to acquire the data from Vantor.
A large subset of Vantor’s data holdings are available for download using NASA Earthdata Search.
*Note: Vantor data are also made available to USG funded investigators through the EOCL contract. This contract permits access to archived declassified imagery as well as new tasking acquisitions. *
