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-admin 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 commandgdal_translate -co "TFW=YES" in.tif out.tif
. It will generate a new
.tif
file with its.tfw
metadata file.
