NASA's Commercial Satellite Data Acquisition (CSDA) program provides United States (U.S.) Government access to the German Aerospace Center (DLR) Earth Sensing Imaging Spectroradiometer (DESIS), a hyperspectral remote sensor spanning 400-1000 nm and imaging from onboard the International Space Station (ISS). The unique orbit and highly detailed surface reflectance spectrum offers opportunities to test and develop new algorithms focused on land surface vegetation and water quality.
CSDA maintains an Indefinite Delivery, Indefinite Quantity (IDIQ) contract with Teledyne Brown Engineering for DESIS data. Under this contract, a program or agency desiring DESIS data can contact the CSDA program and work with them to provie requirements and agree on funding for a new task order. CSDA's previously purchased DESIS data for the period November 2018-May 2024 is available to U.S. Government users.
| Platform | Temporal Frequency | Horizontal Resolution | Geographic Domain | Spectral Bands | Thematic Areas |
|---|---|---|---|---|---|
| DESIS-on-International Space Station | 3-5 days | 30 m | 55°N to 52°S | 1000 (402 nm to 1000 nm) | Disaster Response, Earth Surface and Interior, Land Cover and Land Use Change, Water and Energy Cycle |
Improved access to data products from commercial systems, reduced latency acquisitions, and improved derivation of new research and operational products will enable new opportunities for research and applications across thematic areas.
