Basically, the Implementation Agreement (IA), that established the partnership, instituted the commercial sale of ALI and Hyperion imagery and allowed the USGS EROS Data Center (EDC) to assume the responsibility for all customer interface services related to the acquisition, archival, and distribution of EO-1 image data. EO-1 archives of ALI and Hyperion data can be directly queried and ordered with the Earth Explorer interface (http://earthexplorer.usgs.gov). Data Acquisition Requests (DARs) for tasking the spacecraft are to be made through the USGS, should archive data not be available for an area of interest. Further information can be obtained from the USGS website at http://eo1.usgs.gov.
Pricing for new image acquisition tasks, as well as sale of data sets from the archive, were set based on Landsat imagery prices. Each agency invested FY02 funds to start the partnership. NASA funding was applied to continuing satellite operations and science support activities. USGS funding established the ground station downlink operations, level 0 and level 1 processing, archive, distribution, user services, and observatory scheduling functions at EDC. The roles and responsibilities for each agency in implementing this agreement are listed below.
NASA's role in the EO-1 Extended Mission partnership is as follows:
- Maintain ownership of spacecraft
- Conduct command and control operations
The USGS role is as follows:
- Eventually perform satellite decommissioning and de-orbit maneuver
- Serve as customer interface
- Manage data capture operations
- Perform ALI/Hyperion scheduling and tasking
- Perform data processing and product distribution
- Function as long term archive facility
