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


➜  ~ gdaldem aspect /Users/Harlock/Downloads/DTM10M/50000_460.asc
/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
