The command "gdaldem hillshade" is used to create a hillshade raster image from an input raster image file.
Here's a breakdown of the command:
-
"gdaldem": This is the command-line tool for using the GDAL (Geospatial Data Abstraction Library) software, which is used for working with geospatial data.
-
"hillshade": This is the specific algorithm or function within gdaldem that creates the hillshade image.
-
"${path-to-input-tif}": This is the path to the input raster image file. Replace "${path-to-input-tif}" with the actual file path and name of the input raster image that you want to create a hillshade from. The file format is TIF (Tagged Image File Format), but GDAL supports various other geospatial file formats as well.
-
"${path-to-output-tif}": This is the path to the output raster image file, where the resulting hillshade image will be saved. Replace "${path-to-output-tif}" with the desired file path and name for the output hillshade file. Again, the file format will be TIF.
Make sure to replace "${path-to-input-tif}" and "${path-to-output-tif}" with the actual file paths before running the command.
