Frequently asked questions
Can I see a digital terrain model in 3D?
Yes. An elevation GeoTIFF is shown as shaded relief, coloured by elevation, or as a 3D view you can rotate.
Do I need a Shapefile's .dbf and .prj files?
They are read if they sit next to the .shp: attributes are shown with the features, and the coordinate system is given in plain words.
