Landsat Missions
Approximately 100 days after launch, about 400 scenes will be acquired each day by the Landsat Data Continuity Mission (LDCM) and archived at the USGS EROS Center. All scenes will be processed to Level-1 products, consistent with current standard Landsat data products. LDCM scenes will be available for download within 24 hours of reception and archiving.
LDCM will carry two pushbroom sensors: Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS). The OLI will collect data in nine shortwave bands - eight spectral bands at 30-meter resolution, and one panchromatic band at 15 meters. Refined heritage bands and the addition of a new coastal/aerosol band, as well as a new cirrus band will create data products with improved radiometric performance. The TIRS will capture data in two longwave thermal bands with a minimum of 100 meter resolution, but will be registered to and delivered with the OLI data product.
A new Quality Assurance band will also be included with each data product. This will provide information on the presence of features such as clouds, water, and snow. Details on the LDCM Band Designations can be found on the Band Designation page.
The LDCM data product file size will be significantly larger than existing Landsat data products, due to greater radiometric quantization, increased number of bands, and the addition of a Quality Assurance band.
