Hey @planemad, what software did you use to generate the diffs?

[planemad]

@ramSeraph Used https://github.com/mapbox/road-diff/tree/geosadak-diff which does a tile based computing of two input mbtiles.

Have already created a geosadak.mbtiles which includes all the pmgsy data. Whats a good place to host the mbtiles so it does not need to be generated again by others?

[ramSeraph]

I can host it on GCS for now. Or you can commit to GitHub.. maybe. I asked because I attempted with hootenanny and mashnet.. none of them did as well as the diff you generated. I was thinking of further matching the diff with fb roads for getting higher confidence data. I also think the diff can be directly made available through mapwithai josm plugin. I can work on making that happen.

Output size

• Geosadak dataset: mbtiles: 500MB
• Road diff: geojsonl: 1GB, mbtiles 200MB.

@ramSeraph message me details on uploading to GCS
