Background
NASA's Commercial Satellite Data Acquisition (CSDA) program provides U.S. government access to German Aerospace Agency (DLR) Earth Imaging Spectroradiometer (DESIS) data based on recommendations from the Satellite Needs Working Group (SNWG). DESIS is a hyperspectral remote sensor (spanning 400-1000 nm) that collects data from aboard the International Space Station (ISS). The unique ISS orbit and the highly detailed surface reflectance spectrum offers opportunities to test and develop new algorithms focused on land surface vegetation and water quality.
Status: Available Now
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 to work with them to provide requirements and to agree on funding for a new task order. CSDA's previously purchased DESIS data for the period November 2018 to May 2024 is available to U.S. government users.
Characteristics
| Platform | Temporal Frequency | Horizontal Resolution | Geographic Domain | Spectral Bands |
|---|---|---|---|---|
| DESIS-on-International Space Station | 3-5 days | 30 m | 55°N to 52°S | 1000 (402 nm to 1000 nm) |
Societal Impact
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. Additional insights on land surface vegetation and water quality will support crop monitoring, irrigation timing, and other land assessment needs.
