[GRASS-user] Radiometric Correction @GRASS6.4

[Nikos Dumakis]

In order to ensure that the remote sensing data sets are consistent and that
changes identified through multi-temporal analysis are indeed actual changes
in surface properties and not triggered by changed illumination and
extinction conditions, it is important to correct for effects of atmospheric
attenuation of the signal recorded at the sensor, as well as for
illumination variations within the scenes resulting from the
sun-sensor-surface constellation.

As far as I saw, there are no GRASS functions to perform Radiometric
Correction. The only reference that I found was related with Conversion of
DN's to absolute radiance values==> GRASS book refers it as Image
Calibration from DN to apparent radiance at sensor.
Is there any function to perform radiometric correction? or anyone has
developed something like that?

Thanks

Best regards,
Nikos
