It started with a question about small shops.
CaCoOb began with an article about the loss of small, long-running shops in central Cagliari. Could open data show whether the pattern was visible on the map?
This map puts OpenStreetMap records side by side over time: shops, cafés, services, and craft businesses.

Street by street.
Change compares the number of entries in the same cell across two years. Density counts places in the current map: darker means more. Use Points to open individual places.
The numbers also change when someone updates OpenStreetMap. A shop added yesterday may have been there for twenty years. Coverage depends on contributors; vacancy and disuse tags need checking on the ground.
