Dear all,

I am a student from India, and first time user of GRASS GIS and i am having basic knowledge of GIS.
My aim is to use i.landsat8.swlst add-on to calculate LST from Landsat8 data for my study area.
I want to know in the following command:

i.landsat8.swlst mtl=MTL prefix=B landcover=FROM_GLC -n

​Which Basename i am going to provide as prefix for landsat8 data ??

Also, my first query on grass-user’s mail list.
Please help.

Regards

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I would NOT use a one of the rather outdated GLC maps (which for my study area in addition were full of NoData).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).

Kind regards,

Stefan

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.

Regards
John
