Nowadays, with the help of a 3D printer, it has become very easy to print 3D geographic features captured by a Digital Elevation Model. To be able to do that, a raster export to STL (standard triangle language) format is mandatory. This can be realized with the help of QGIS software and its DEMto3D plugin. [...]
