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 Archive (SA), Ingest System (IS), Subsetter System (SS), Image Assessment System (IAS), Level 1 Product Generation System (LPGS), and User Portal (UP). These subsystems will work together to ingest, store, and archive LDCM data and will also generate LDCM data products for distribution.

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 for the LDCM imaging sensors each day. The MOE will translate the activity requests into software command loads transmitted to the observatory.

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 Element, and the Data Processing and Archive System.

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

< Operational Land Imager (OLI) OLI Design >   The OLI requirements specified a sensor that collects image data for nine spectral bands with a
