mvexel - Why would MR produce an unusable file when converting a .osm file to a geojson file? Is there something I missed? Frustratingly the native:forcerhr algorithm isn’t in my algorithm list in QGIS…so not sure how to fix that… This tool from Mapster also didn’t work: Mapster GeoJSON Right-Hand-Rule Rewinder. - It produced a json file.

Thanks for this, ran through the steps as in the post but saw a lot of “GeoJSON error: Polygons and MultiPolygons should follow the right-hand rule” errors when uploading to MapRoulette?
