I'm currently performing an analysis in QGIS that involves calculating areas (see this question). In order to do so, I would like to work in an equal area projection, like
EPSG:6933. I already set the project as a whole to this CRS in the Properties section.
Now, I'd like to convert all the relevant layers to this CRS. I'm starting off with the base layer - Esri Gray (light). When I do Export, Save as... and set it to
EPSG:6933 in the menu (and tick off 'create VRT'), something goes wrong. I get the follow error message when I try to save the layer in the new projection:
The output mode in the Save raster data as... menu was 'Raw data'.
Questions: how should I reproject the base (raster) layer correctly? And do I have to reproject all layers everytime, or is there a way to set the whole analysis in one layer setting?
