I need to make some pretty basemaps and wish to use QGIS. The program which will use the basemaps is GrADS, which doesn't read any navigated imagery like geoTIFF or kml. However it produces KML files. So I can specify the exact domain for QGIS to render.
The rectangle represents the area I wish to output at 1920x1080 pixels.
I know how to make the maps I want, but how do I limit them to this exact space and output dimension?
