Part of osmose that runs the analysis, and send the results to the frontend.

Backend part of the Osmose QA tool

This is the part of Osmose which analyses OSM and sends the results to the frontend. This works as follows:

  • an .osm.pbf extraction is downloaded
  • analyses are run directly on the .osm.pbf file, or on the database
  • results of the analyses are uploaded to the frontend
  • by default, the database is purged

Analysers can be build in many ways:

  • With MapCSS rules validating each OSM objects: plugins/*.mapcss and JOSM MapCSS core and some contrib rules.
  • With Python code validating each OSM objects: plugins.
  • With SQL/PostGIS queries on the Osmosis database: analysers/analyser_osmosis_*.py.
  • By configuring a comparator of OpenData and OSM objects: analysers/analyser_merge_*.py.
