usage: valhalla_build_elevation [-h] [-g FROM_GEOJSON | -b FROM_BBOX | -t] [-c CONFIG] [-i INLINE_CONFIG] [-o OUTDIR] [-p PARALLELISM] [-v] [-d | -z] Downloads Tilezen's elevation tiles that either intersect with features in all .geojson files in --input-geojson-dir or that intersect with --bbox. NOTE: geojson method requires shapely. options: -h, --help show this help message and exit -g, --from-geojson FROM_GEOJSON Absolute or relative path to directory with .geojson files used as input to tile intersection. Requires shapely. -b, --from-bbox FROM_BBOX Bounding box coordinates in the format 'minX,minY,maxX,maxY'. -t, --from-tiles Only download tiles covered by the Valhalla graph (requires a Valhalla config JSON file). -c, --config CONFIG Absolute or relative path to the Valhalla config JSON. If present, can be used for download location and bbox. -i, --inline-config INLINE_CONFIG Inline JSON config, will override --config JSON if present -o, --outdir OUTDIR Absolute or relative path to the directory where the tiles will be saved. Overrides config JSON. -p, --parallelism PARALLELISM Number of processing units to use. -v, --verbosity Accumulative verbosity flags; -v: INFO, -vv: DEBUG -d, --decompress If set, downloaded files will be decompressed (default format is gzip). -z, --lz4 If set, downloaded files will be recompressed with LZ4. Requires lz4. Requires ~12% more disk space (216GB total) vs gzip. While you pay upfront in extra CPU and space on the initial download, tiles will be several times faster to decompress vz gzip.
