OSM coverage gaps over time

How many City of Guelph bus stops are still missing from OpenStreetMap, mapped without their ref, or mapped under a different name, and how many OSM stops carry a number the City no longer lists — one point per weekly comparison, so a mapper can see the worklist shrink.

1 comparisons since 2026-10-09 · last 2026-10-09 · current gaps · data (JSONL)

Points in the shaded span are reconstructed after the fact from OSM's own history (an Overpass attic query for that date, compared against today's City stops); the rest were observed by the weekly build. Counts follow the City's Bus Stops layer, so they move when the City adds, retires or renames stops, not only when someone maps one.
