OSM QA Tiles are now being updated daily for the entire world on osmlab.github.io as mbtiles. OSM QA Tiles contain the full spectrum of OpenStreetMap data at full fidelity. Use them with Tile Reduce to conflate OpenStreetMap with other datasets, detect bugs like connectivity issues, or monitor for vandalism - you can do nearly any tile-based analysis of OpenStreetMap data.
OSM QA Tiles contain the full spectrum of OpenStreetMap data for analysis.
To analyze the data in OSM QA Tiles, you can write simple Turf.js based processors in Tile Reduce. Tile Reduce is a geospatial MapReduce library for running custom processors across all tiles in a given area. Tile Reduce handles scaling these processors across all available cores on a machine, and it exposes data as GeoJSON, making processors easy to write and understand.
Here are two examples of how to build simple data analysis with OSM QA Tiles and Tile Reduce.
