Positional arguments: -i, --input Input raster datasets [required] [not available in pipelines] -o, --output Output vector dataset [required] [not available in pipelines] Common Options: -h, --help Display help message and exit --json-usage Display usage as JSON document and exit --config = Configuration option [may be repeated] -q, --quiet Quiet mode (no progress bar or warning message) [not available in pipelines] Options: -f, --of, --format, --output-format Output format ("GDALG" allowed) [not available in pipelines] --co, --creation-option = Creation option [may be repeated] [not available in pipelines] --lco, --layer-creation-option = Layer creation option [may be repeated] [not available in pipelines] --overwrite Whether overwriting existing output dataset is allowed [not available in pipelines] --output-layer Output layer name -b, --band Input band (1-based index) (default: 1) --elevation-name Name of the elevation field --min-name Name of the minimum elevation field --max-name Name of the maximum elevation field --3d Force production of 3D vectors instead of 2D --input-nodata Input pixel value to treat as 'nodata' --interval Elevation interval between contours Mutually exclusive with --levels, --exp-base --levels List of contour levels [may be repeated] Mutually exclusive with --interval, --exp-base -e, --exp-base Base for exponential contour level generation Mutually exclusive with --interval, --levels --off, --offset Offset to apply to contour levels -p, --polygonize Create polygons instead of lines --group-transactions Group n features per transaction (default 100 000) Advanced Options: --if, --input-format Input formats [may be repeated] [not available in pipelines] --oo, --open-option = Open options [may be repeated] [not available in pipelines] --output-oo, --output-open-option = Output open options [may be repeated] [not available in pipelines] >>>>>>> (DESCRIPTION) >>>>> gdal raster contour >>>> >>>>>> (>>>>) >>>>>> >> >> >> >>>
