landsat process reprojects from native CRS to EPSG:3857 #228

Hello, I do not know why landsat process changed projection while generating an RGB tif file. I need it in the original CRS. Can this be customized or avoided somehow? thank you in advance. Maroi.

Hi @negroscuro , there is currently no option to specify that, or turn off reprojection, although it's something that should definitely be added. For now, as a workaround, you should be able to edit the two lines here https://github.com/developmentseed/landsat-util/blob/develop/landsat/image.py#L71

Just drop in the EPSG code for the correct UTM projection of your scene.

Thank you very much for the landsat-tool itself, it is useful, and also thank you for answering about this.

I noticed this because i am loading landsat data with time dimension into a tool that is giving me problems because of resolution changes, when a raster is reprojected the resolution slightly changed and then it is not possible to import it by using the tool since time dimension is restricting data upload requirements.

cheers, Mario.
