Clearance
Curating changes to OpenStreetMap data of interest
Clearance is an open-source tool designed to enhance the reliability and increase confidence in collaborative OpenStreetMap (OSM) data by acting as a quality control proxy between OSM and data consumers and functioning as a standard OSM data source (OSM PBF or overpass API).
OSM map data is created collaboratively and continuously updated by the contributor community. While most changes are made in good faith, low quality changes or mistakes may occur, especially by beginners. Bad faith changes also exist, but are less frequent. When you rely on OSM data, as a service provider or end user, quality and avoiding breaking changes is important. That's the issue Clearance addresses.
Clearance holds suspicious or potentially problematic changes, while keeping replication up to date for those respecting quality rules. It reworks OSM changes into coherent groups based on topological, geospatial, and semantic object relationships. Rejected data groups must be corrected in OSM or accepted manually. It provides local atomic changes that preserve data integrity. It helps identify semantically equivalent objects despite technical changes (splits, merges, redraws, dimension changes).
