GDAL-VECTOR-SEGMENTIZE(1) GDAL GDAL-VECTOR-SEGMENTIZE(1) (NAME) gdal-vector-segmentize - 3.12. (SYNOPSIS) Usage: gdal vector segmentize [OPTIONS] Segmentize geometries of a vector dataset. Positional arguments: -i, --input Input vector datasets [required] [not available in pipelines] -o, --output Output vector dataset [required] [not available in pipelines] --max-length Maximum length of a segment [required] 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: -l, --layer, --input-layer Input layer name(s) [may be repeated] [not available in pipelines] -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] --update Whether to open existing dataset in update mode [not available in pipelines] --overwrite-layer Whether overwriting existing output layer is allowed [not available in pipelines] --append Whether appending to existing layer is allowed [not available in pipelines] Mutually exclusive with --upsert --output-layer Output layer name [not available in pipelines] --skip-errors Skip errors when writing features [not available in pipelines] --active-layer Set active layer (if not specified, all) --active-geometry Geometry field name to which to restrict the processing (if not specified, all) 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] --upsert Upsert features (implies 'append') [not available in pipelines] Mutually exclusive with --append (DESCRIPTION) gdal vector segmentize LineString Polygon .
