Landsat Missions
As of March 31, 2004, Landsat 7 Enhanced Thematic Mapper Plus (ETM+) data will no longer be available for search and order through the Land Processing Distributed Active Archive Center (LP DAAC) and the Earth Observing System (EOS) Data Gateway (EDG). All orders submitted to the LP DAAC prior to this date will be filled, provided payment is received within a reasonable amount of time. Search, browse, and order capability for most of these datasets will be migrated to Earth Explorer in the near future.
This change is driven by long standing agreements to transfer land remotely sensed data from National Aeronautics and Space Administration (NASA) to the U.S. Geological Survey (USGS) for long-term archiving, as well as specific agreements made between NASA and the USGS during the Landsat 7 Project. Both agencies will be working to make the transfer as seamless to the user as possible, and to continue the current high level of service.
Although the method of data access will change, there will be no other change to the processing, format, or other details of the products. Level 1 and Level 0 products that were previously available through the EDG will now be accessed through the EarthExplorer or the Global Visualization Viewer (GloVis). Level 1 products will continue to be available through both processing systems currently in use (LPGS or NLAPS), with the temporary exception of floating scenes.
The projected status of each Landsat 7 ETM+ data set is as follows:
| Product | Status |
| LANDSAT 7 LEVEL-0R WRS-SCENE V002 | available on EarthExplorer and GloVis on 3/31/04 |
| LANDSAT 7 LEVEL-1 WRS-SCENE V002 | available on EarthExplorer and GloVis on 3/31/04 |
| LANDSAT 7 LEVEL-0R WRS-SCENE SLC-OFF V003 | available on EarthExplorer and GloVis on 3/31/04 |
| LANDSAT 7 LEVEL-1 WRS-SCENE SLC-OFF V003 | available on EarthExplorer and GloVis on 3/31/04 |
| LANDSAT 7 LEVEL-1 FLOATING SCENES V002 | available on Earth Explorer by Fall, 2004* |
| LANDSAT 7 LEVEL-OR FLOATING SCENES V002 | available on Earth Explorer by Fall, 2004* |
| LANDSAT 7 LEVEL-0R FLOATING SCENES SLC-OFF V003 | available on Earth Explorer by Fall, 2004* |
| LANDSAT 7 LEVEL-1 FLOATING SCENES SLC-OFF V003 | available on Earth Explorer by Fall, 2004* |
| LANDSAT 7 CALIBRATION PARAMETER FILE V002 | available today on the Landsat 7 CPF web page |
| LANDSAT 7 LEVEL-0R IGS-SCENE METADATA V002 | availability TBD; contact IGS ground stations |
* Until the search and order capability for floating scene products is released on Earth Explorer, all floating scene and multi-scene orders must be placed by contacting USGS Earth Resources Observation and Science (EROS) Customer Services, and will be processed only through the NLAPS processing system.
If you have any questions, please contact USGS EROS Customer Services.
