Load MNT raster¶
In QGIS, you can visualize your DEM, or merge several tiles together (in Raster > Misc > Merge).
Generate a GeoTIFF, and upload both files (.tif
+ .tfw
) on the server.
And use the Geotrek command to load it into PostGIS :
sudo geotrek loaddem <PATH>/dem.tif
note: | This command makes use of GDAL and raster2pgsql internally. It
therefore supports all GDAL raster input formats. You can list these formats
with the command raster2pgsql -G . |
---|---|
note: | If you only have a .tif file, you can generate the .tfw file with the command gdal_translate -co "TFW=YES" in.tif out.tif . It will generate a new .tif file with its .tfw metadata file. |
