[GRASS-user] calibration of the Landsat thermal data

[Niels Thevs]

Dear Grass users,

does anybody have experience with the calibration of the Landsat thermal 
data ? I have a few ground measurements of temperature (air temperature 
in 2 m above surface) and want to relate them to a corresponding Landsat 
image (band 6). In the papers which I read there are listed a lot of 
working steps like calibration for at sensor radiance, surface radiance, 
etc. Is it necessary to do all those steps or does anybody know a more 
simple algorithm ?

Best regards

Niels
