$ osmium extract -p ${path-to-polygon-geojson} ${path-to-input-pbf} -o ${path-to-output-pbf}
try on your machine
The command you provided is using the osmium tool for manipulating OpenStreetMap data. It specifically uses the "extract" subcommand to extract a specific area of interest from an input PBF file and save it as a new output PBF file.
Here is a breakdown of the command:
- "osmium": This is the main command for using the osmium tool.
- "extract": This is the subcommand telling osmium to perform an extraction operation.
- "-p ${path-to-polygon-geojson}": This option specifies the path to a polygon GeoJSON file that defines the area of interest for the extraction. The GeoJSON file contains the coordinates of a polygon that represents the desired bounding box for the extraction.
- "${path-to-input-pbf}": This is the path to the input PBF file from which the data will be extracted.
- "-o ${path-to-output-pbf}": This option specifies the output path for the resulting extracted data. The extracted data will be saved as a new PBF file at this location.
In summary, this command takes an input PBF file, extracts the OpenStreetMap data within the specified polygon area defined by the GeoJSON file, and saves the extracted data as a new PBF file at the specified output path.

never run a command you are not sure if it is safe.
