OLI & TIRS - Products Information
The Landsat 8 OLI and TIRS data products are processed by ESA on a Near-Real Time (NRT) basis using the USGS processor, and are released to the users with ortho-rectified specifications consistent with all standard Level 1 data products. Where possible, Standard Terrain Corrected products are produced, however where this is not possible, Systematic Terrain Corrected products are produced:
The Landsat 8 images consist of nine spectral bands, which are all acquired at 30 metre resolution, apart from the two TIRS bands which are acquired at 100 metres and resampled to 30 metres. On a scene-by-scene basis, there is also a quality assessment band included with each product which addresses the conditions that could affect the usefulness of the product. More information about this band is available here
The European Space Agency (ESA) acquires Landsat data over Europe through the ESA ground stations, in co-operation with the USGS and NASA.
In terms of algorithms for Landsat 8, these are maintained by the USGS and are defined in the LDCM Algorithm Description Document
