[GRASS-user] Query Related to i.landsat8.swlst

[Blumentrath, Stefan]

Hei Eddison,

There was a question about i.landsat8.swlst on the GRASS user mailing list very recently:
https://lists.osgeo.org/pipermail/grass-user/2016-September/075134.html
Maybe the answer is useful for you too.

In general it is advisable to send such questions to the mailing list. There are more people who can answer or give you advise.

As for your specific question:
Yes, you can run i.landsat8.swlst only with band 10 and 11. Yet, you may be interested in excluding invalid pixels using the QA band (BQA). You can do that in i.landsat8.swlst or using the i.landsat8.qc addon (https://grass.osgeo.org/grass70/manuals/addons/i.landsat8.qc.html). In this case you would have to import band QBA too.

If you are concerned about data duplication, you can use r.external (https://grass.osgeo.org/grass70/manuals/r.external.html)  to just link the bands to your GRASS DB.

Cheers
Stefan

Subject: Query Related to i.landsat8.swlst

Estimado amigo, un gusto saludarte desde Costa Rica, deseo correr el proceso i.landsat8.swlst.

Lo primero que debo hacer es importar "todas" las bandas de la escena Landsat8? por ejemplo:


[Imágenes integradas 1]

En ese caso importo todas las bandas? o solo importo a GRASS la Banda 10 y 11?

Disculpe mi ignorancia, no uso GRASS pero necesito correr el proceso i.landsat8.swlst

Gracias

Eddison
