It's a hyperspectral, airborne sensor. There are 60 bands in the range from 405 to 951 nm (about a 9,2 nm - step).</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">So my question(s)... Is it possible to implement a new hyperspectral, airborne sensors in i.atcorr? I know there is already a hyperspectral satellite sensor included.</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">If it is possible, how much time will be roughly consumed to undertake this task? Days, weeks or months?</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">Furthermore, I've already read the i.atcorr README to "add new band filters" (<a href="http://trac.osgeo.org/grass/browser/grass/trunk/imagery/i.atcorr/README">http://trac.osgeo.org/grass/browser/grass/trunk/imagery/i.atcorr/README</a>), but I'm an absolute beginner, so unfortunately I wasn't able to figure out how to create the needed filter function.</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">Can somebody point me in the right direction please?</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">Thanks for your effords!</p><p style="font-family: Verdana, Geneva, sans-serif; font-size: 13px; ">Alexander K.</p></body></html>
