New OSM based Map Website.
We use open data from OSM.org , a platform with over a million volunteers world wide, updating the map, roads, locations etc in their area. This includes any shops.
Hopefully it keeps alive and does not die (like similar Qwant Maps)
Yes, it’s possible, and there are few examples, the point is it’s much more complex to implement it than just slapping router on top of the map.
Sure, I appreciate that it’s more complicated due to there not being a connected road graph in the same way as there is for other modes of transport. But at the very least showing the main transit arteries (metro & light rail) prominently would already go a long way, if nothing else than to help identify places by their nearest transit stop.
There is also a Transit layer on osmapp :)
