The importance of the calibration of the AVHRRs for better remote sensing and GIS data integration

Crackmell A.P., . and Ibrahim Busu, . (1995) The importance of the calibration of the AVHRRs for better remote sensing and GIS data integration. [Proceedings Paper]

Remote sensing images of the Earth have been regarded by many as one important source of data for Geographic Information Systems GISs. Much effort has been directed towards solving problems in data integration between remote sensing and GISs. However there are still many problems remaining to be solvedthese include the problem of archived AVHRR data channels 1 and 2 whic is affected by systematic errors due to the sensor degradation and multiple sensors of different characteristics. The systematic error exist in the archived data because there is no on-board calibration facility available on the NOAA series satellites for channels 1 and 2 of the AVHRR. In order to produce good data integration between remote sensing and GISs known errors should removed before the remotely-sensed data are integrated with other data sets in the GIS database. This also applies to the archived AHRR datathe systematic error should be removed or eliminated before any of the data are used for time-dependent GIS applications. Over the years a number of post-launch calibration methods and procedures have been suggested and each of these has some advantages and disadvantages over the others. This paper reviews a number of post-launch calibration methods which have been established and used by others in order to search and recommend the most suitable one for general users of AVHRR archieved data.

Abstract

Remote sensing images of the Earth have been regarded by many as one important source of data for Geographic Information Systems GISs. Much effort has been directed towards solving problems in data integration between remote sensing and GISs. However there are still many problems remaining to be solvedthese include the problem of archived AVHRR data channels 1 and 2 whic is affected by systematic errors due to the sensor degradation and multiple sensors of different characteristics. The systematic error exist in the archived data because there is no on-board calibration facility available on the NOAA series satellites for channels 1 and 2 of the AVHRR. In order to produce good data integration between remote sensing and GISs known errors should removed before the remotely-sensed data are integrated with other data sets in the GIS database. This also applies to the archived AHRR datathe systematic error should be removed or eliminated before any of the data are used for time-dependent GIS applications. Over the years a number of post-launch calibration methods and procedures have been suggested and each of these has some advantages and disadvantages over the others. This paper reviews a number of post-launch calibration methods which have been established and used by others in order to search and recommend the most suitable one for general users of AVHRR archieved data.
