Dear Grass List,
I am trying to do radiometric classifications on Landsat 7 SLC-Off imagery (i.e. it has lots of NULL data). My question is regarding i.smap. The documentation says:
“The module i.smap does not support MASKed or NULL cells. Therefore it might be necessary to create a copy of the classification results using e.g. r.mapcalc.”
Does this mean i.smap will not work correctly with Landsat 7 SLC-Off imagery? When I try i.gensigset and i.smap I get results, but I’m not sure if I can trust them due to the disclaimer.
Thanks for any help or advice,
Nick
