niente da fare
Se do il comando dal terminale ecco il risultato

/Users/Harlock/Downloads/DTM10M/Merge/Ombra.asc -of AAIGrid -b 1
Usage:
- To generate a shaded relief map from any GDAL-supported elevation raster
:
gdaldem hillshade input_dem output_hillshade
[-z ZFactor (default=1)] [-s scale* (default=1)]
[-az Azimuth (default=315)] [-alt Altitude (default=45)]
[-alg ZevenbergenThorne] [-combined]
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
- To generates a slope map from any GDAL-supported elevation raster :
gdaldem slope input_dem output_slope_map
[-p use percent slope (default=degrees)] [-s scale*
(default=1)]
[-alg ZevenbergenThorne]
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
- To generate an aspect map from any GDAL-supported elevation raster
Outputs a 32-bit float tiff with pixel values from 0-360 indicating
azimuth :
gdaldem aspect input_dem output_aspect_map
[-trigonometric] [-zero_for_flat]
[-alg ZevenbergenThorne]
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
- To generate a color relief map from any GDAL-supported elevation raster
gdaldem color-relief input_dem color_text_file output_color_relief_map
[-alpha] [-exact_color_entry | -nearest_color_entry]
[-b Band (default=1)] [-of format] [-co "NAME=VALUE"]* [-q]
where color_text_file contains lines of the format "elevation_value red
green blue"
- To generate a Terrain Ruggedness Index (TRI) map from any GDAL-supported
elevation raster
gdaldem TRI input_dem output_TRI_map
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
- To generate a Topographic Position Index (TPI) map from any
GDAL-supported elevation raster
gdaldem TPI input_dem output_TPI_map
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
- To generate a roughness map from any GDAL-supported elevation raster
gdaldem roughness input_dem output_roughness_map
[-compute_edges] [-b Band (default=1)] [-of format] [-co
"NAME=VALUE"]* [-q]
Notes :
Scale is the ratio of vertical units to horizontal
for Feet:Latlong use scale=370400, for Meters:LatLong use scale=111120
