a Topographic Position Index (TPI) map Positional arguments: -i, --input Input raster datasets [required] [not available in pipelines] -o, --output Output raster 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] --overwrite Whether overwriting existing output dataset is allowed [not available in pipelines] Mutually exclusive with --append --append Append as a subdataset to existing output [not available in pipelines] Mutually exclusive with --overwrite -b, --band Input band (1-based index) (default: 1) --no-edges Do not try to interpolate values at dataset edges or close to nodata values 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] >>>>>>> (DESCRIPTION) >>>>> gdal raster tpi >> >>>> >>>>>>>> >> >>>>>> >>>>>>>>>> >> >>> >>>>>>>> >>>>>>> >>>>> >>>>>>. >>>> TPI >>>> Topographic Position Index
