This is a topographic model of a region in southeast Asia called the Bolaven Plateau, located in the south of the Lao People's Democratic Republic (Lao PDR / Laos). The model was derived from a digital elevation model (DEM) raster that was modified using a free open source geographic information system (GIS) software platform: QGIS. An open source plugin, DEMto3D, that runs on top of QGIS (or on top of another open source GIS platform: Kosmo) allowed conversion from DEM raster format to STL format.
The scale of this topographic model is 1:100,000,000. Elevation values are exaggerated by a magnitude of five (5) to accentuate the pronouncement of this large plateau/tableland feature in mainland southeast Asia.
