Dear Grass List,<div><br></div><div>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:</div><div><br></div>
<div><meta http-equiv="content-type" content="text/html; charset=utf-8"><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: medium; ">"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."</span></div>
<div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: medium; "><span class="Apple-style-span" style="font-family: arial; font-size: small; "><br></span></span></div><div><span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: medium; "><span class="Apple-style-span" style="font-family: arial; font-size: small; ">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. </span></span></div>
