DEM Visualization

Display the elevation model “eth_dem_fin”, use as Representation “ElevationMeter”, check the map values and then close the map. From the main ILWIS menu select the option “Operations” > “Dem Hydro‐processing” > “DEM Visualization”, use “eth_dem_fin” as DEM, leave the output name as default and press “OK”. The operation conducted creates from the DEM illumination directions using linear filters from west, north‐west and north directions. Subsequently these are merged in an output map. Once the map is calculated the results are displayed in a new map window. Add the DEM “eth_dem_fin”, using as representation “ElevationMeter”. Under the Display Tools options for this map, click on transparency and set the transparency to 45 %, eventually add the base map “country boundaries”, but change the boundary color to black
