[GRASS-user] i.atcorr problems for ALOS, Ikonos and RapidEye

Dear list,

I just realized that there are some problems with the filter functions
used to do the atmospheric correction for the Alos AVNIR2, Ikonos and
RapidEye sensors. I expect to fix some of those bugs this week so
please, use i.atcorr with care if you work with these sensors.

Sorry for the inconvenience

Off-list Daniel and Anne Ghisla have fixed the AVNIR2 problems and
also updated accordingly the Ikonos and RapidEye sensor functions.

Fixed in SVN for 6.4 (will go into 6.4.1), 6.5 and 7.

Dear list

Is there any initiatives about updating with WorldView-2 (+ QB and WV1?) sensor functions in i.atcorr?

We could "easily" add those but need to get the sensor functions as CSV file.
Can you obtain them?

Hi Markus

Thx. Can you supply me with a CSV file for the existing sensor functions, e.g. Ikonos? I need to know a bit more on the exact information needed in these sensor functions?

Cheers,
Rasmus

sure, we have recently added them in the source code directory:

http://trac.osgeo.org/grass/browser/grass/branches/releasebranch_6_4/imagery/i.atcorr/sensors_csv
-> various files
