I have a big list of locations with their coordinates in a city that is fully divided by a river that's running from north to south. Now I want to determine for each location if it is located east or west of that river. If it was possible to get the coordinates of the river in a granular enough manner, I could achieve that goal by comparing coordinates between location and the river. I have not found a way to get these coordinates so far. I'm new to OSM, however, and would be thrilled if someone could point me in the right direction here.
