gdal_contour

Create contour lines and polygons from a digital elevation model. More information: https://gdal.org/programs/gdal_contour.html.

• Create a vector dataset with contour lines spread over an 100-meter [i]nterval while [a]ttributing the elevation property as "ele":

gdal_contour -a {{ele}} -i {{100.0}} {{path/to/input.tif}} {{path/to/output.gpkg}}

• Create a vector dataset with [p]olygons spread over an 100-meter [i]nterval:

gdal_contour -i {{100.0}} -p {{path/to/input.tif}} {{path/to/output.gpkg}}
