I am trying to import a GeoTiff (.tif) into GRASS GIS. I then want it to show up in the map display.
This is the data I want to use: http://ghsl.jrc.ec.europa.eu/ghs_pop.php
As far as I can tell, this is raster data. I know the location and the dataset must share the same projection. When I set up the location, I selected "Read projection and datum terms from georeferenced file". GRASS GIS correctly read projection and datum.
Now, I selected the location I just created, and the predefined mapset "PERMANENT". Then I hit "Start GRASS Session".
But now I'm just seeing a purple rectangle. See this screenshot:
I'm not quite sure what's going wrong.
Background: I am to visualize the population growth in south america. Our college course didn't do anything to prepare me for this so I have to ask such basic questions.
