Discontinued L5 TM Bumper Mode ("Heritage Format") Calibration Files – April 2009

As of 1-April-2009, the USGS has discontinued the preparation and delivery of any new L5 TM Bumper Mode ("Heritage Format") Calibration Files.

The new full L5 TM CPF series (released in May 2007) will continue to be prepared and delivered via previous channels, and is expected to replace the previous bumper mode calibration file format.

The new L5 TM CPF provides a single, robust file containing calibration-related information needed for L5 TM Level 1 processing. Use of the new L5 TM CPF will provide many benefits, including:

single source of calibration coefficients
Improved geometric accuracy
Improved radiometric accuracy
Enhanced Level 1 product quality
Mission-wide CPF readiness:
- structurally very similar to L7 ETM+ CPF
- likely basis for L4 TM CPF and L1-5 MSS CPFs
