Re: [GRASS-user] Query Related to i.landsat8.swlst
Dear Stefan, Thanks a lot for answering my query, i.landsat8.swlst add-on now works fine for me. Thanks for your input regarding use of GLC maps, i use these maps to test the LST add-on.

Re: [GRASS-user] Query Related to i.landsat8.swlst
Hei Johnn, The command you specified is (except for the n-flag) an example from the manual. You would have to replace the input to the options according to your data! I used i.landsat8.swlst in a project in Oslo and was quite satisfied with the results. You can see them here: http://urban.nina.no/layers/geonode%3Alc81980182015183lgn00_lst_const_lc#more I documented the production here: https://github.com/NINAnor/openness/blob/master/oslo_heatmap.sh Maybe the shell script gives you some more hints on the usage of the module in a processing chain... Some hints from my experience with the module: I would NOT use a one of the rather outdated GLC maps (which for my study area in addition were full of NoData). If you have a good land cover map I would reclassify it according to the classes used in the GLC maps (see the manual of i.landsat8.swlst).
