Polylabel_Cmd

…is the command-line version of Polylabel. Install it using cargo install polylabel_cmd.
This gives you the polylabel command.

Use

Polylabel takes one mandatory argument: a path to a valid GeoJSON file, containing any of:

• a FeatureCollection containing Features which are valid Polygons or MultiPolygons
• a Feature containing a valid Polygon or MultiPolygon
• a Geometry which is a valid Polygon or MultiPolygon.

Any non-(Multi)Polygon content is ignored.

It also accepts an optional -t or --tolerance switch, allowing you to fine-tune the tolerance from the default 1.0. Smaller tolerances take longer to calculate.

Output is a GeoJSON FeatureCollection containing Point geometries, in the same order as the input geometries. Note that if the input contained MultiPolygons, the output will be longer as these geometries are individually processed.

Speed

Polylabel is fast. Polygons are processed in parallel, using Rayon.

Binaries

Will be available when I set up CI.

TODO

• Nicer error handling
• Retain properties in output
