ST_ForcePolygonCCW feature request

[duvenagep]

Hi @Maxxen,

Hope this is the right forum but I was hoping to suggest the ST_ForcePolygonCCW function to ensure the RHR (Right-Hand-Rule) is enforced on (Multi)Polygons.

The need for this arises when taking geometry that does not observe the RHR, turning it into Geojson and trying to render it on a map. Some renderers enforce RHR and others don't but will accept RHR geojson.

The below geojson, renders perfect on Mapbox but not my local map renderer.

{"type":"FeatureCollection","features":[{"type":"Feature","geometry":{"type":"Polygon","coordinates":[[[5.988145628397055,50.15505379005275],[5.9881151062563225,50.15502110871649],[5.988072942682381,50.15503697425469],[5.988103488625609,50.15506964664847],[5.988145628397055,50.15505379005275]]]},"properties":{"id":"6e2fcbef-f597-4fd8-84c2-003a4066d35e"}}]}

When I lint my Geojson I get the RHR should be followed error.

To fix my issue, I usually wrap the geometries in ST_ForcePolygonCCW before creating the geojson and everything works.

I hope this can be included in the roadmap for the next release.
