I'm quite new with GRASS but I need to atmospherically process
high-resolution imagery with i.atcorr. I have three images Quickbird,
GeoEye-1 and Worldview-3 imagery of a single scene across three time
periods. For Quickbird, I have all the data needed but basing from the
following manual </span><a rel="nofollow" id="yiv9173098468yui_3_16_0_1_1433296072059_4620" style="" class="" target="_blank" href="http://grass.osgeo.org/grass70/manuals/i.atcorr.html"><span id="yiv9173098468yui_3_16_0_1_1433296072059_4619" class="" style=""></span></a><a style="" class="" rel="nofollow" id="yiv9173098468yui_3_16_0_1_1433296072059_4622" target="_blank" href="http://grass.osgeo.org/grass70/manuals/i.atcorr.html">GRASS GIS manual: i.atcorr</a>

appears to be no

geometrical conditions and band. May I know if GRASS has updated the
i.atcorr
manual to include these sensors as well? </span><span id="yiv9173098468yui_3_16_0_1_1433296072059_5399" class="" style=""><span id="yiv9173098468yui_3_16_0_1_1433296072059_5399" class="" style="">Can I use the values of
