Please note, this is a proof of concept implementation of the OQT, we are constantly working on enhancements (e.g. further indicators, being able to customize the weighting of the different indicators, processing bigger or customized areas of interest).
OQT is a tool that end users, e.g. humanitarian organisations and public administration, can use to get information on the quality of OSM data for their specific region and use-case.
Further, it functions as a data integration tool, that brings together a variety of intrinsic and extrinsic OSM data quality metrics.
