It’s hard to believe a year has passed since the launch of Landsat 8. This first anniversary is going to be an exciting, upbeat celebration because the new satellite is meeting, if not exceeding, all expectations. “Landsat 8 is nearly perfect,” [...]
Within the next several weeks, all Landsat 8 data that have been acquired since achieving WRS-2 operational orbit will be reprocessed using updated calibration parameters for OLI and TIRS data. During this time, all online products will be [...]
The USGS is also developing the DPAS to manage the mission data transmitted from the LDCM observatory. The DPAS will be operated at EROS along with the rest of its Landsat data archive and it will consist of several subsystems: Storage and [...]
A flight operations team (FOT) will operate two computer systems within the MOC, the Collection Activity Planning Element (CAPE) and the Mission Operations Element (MOE). The CAPE will plan science data collection by building activity requests [...]
The Landsat 8 Ground System includes all of the ground-based assets needed to operate the Landsat 8 observatory. The primary components of the Ground System are the Mission Operations Element, Collection Activity Planning Element, Ground Network [...]
The band-average relative spectral radiance responses of the Operational Land Imager (OLI) are provided.
BATC has conducted robust testing of OLI performance in accordance with their proposal and contract. These prelaunch tests indicate that OLI performance meets specification with requirements exceeded in most cases.
< OLI Requirements Pre-launch OLI Performance > The OLI is a push broom sensor employing a focal plane with long arrays of photosensitive detectors (Irons & Dwyer, 2010). A four-mirror anastigmatic telescope focuses incident Read more [...]
< Operational Land Imager (OLI) OLI Design > The OLI requirements specified a sensor that collects image data for nine spectral bands with a spatial resolution of 30 m (15 m panchromatic band) over a 185 km swath from the nominal 705 km [...]
