Previously, GRASS’s i.atcorr function has been very useful when I was analyzing MODIS data. However, there are no presets in the spectrum tables for hyperspectral sensors.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m looking to modify the source of i.atcorr to support correction of Hyperion images, which has 242 bands within the 250—4000 nm spectrum supported by i.atcorr’s 6S implementation. Can anyone point me in the right place where I can make changes or add these bands to i.atcorr’s supported profiles? If I can get this working correctly, I would be willing to submit the code to the project as well, assuming there is interest.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thank you,<o:p></o:p></p><p class=MsoNormal>Abhijit B.<o:p></o:p></p><p class=MsoNormal>Information Sciences Institute<o:p></o:p></p></div></body></html>
