Get the topo map data
Get the topo map, in GeoTiff format. Possible sources are:
Convert to DEM
Convert the GeoTiff file to USGS ASCII DEM (Digitial Elevation Model) format. Possible tools are:
- On Linux: GDAL translate option
sudo apt install gdal-bin gdal_translate -of AAIGrid /yoursourcepath/output_alos.tif /youroutputpath/out.asc
- Or from another program like QGIS. Load your raster file and then from the menu: Raster->Conversion->Translate. You will have to manually edit the command to change the format from GTiff to AAIGrid
DEM to STL
Alternatives
You could import the map image to Blender and edit it there. There is a nice tutorial for that.
