I'm trying to extract gps points on roads in a region. For each road, I need a gps point on that road every 10 meters.
I'm aware that Google Map API offer such way points, but due to the latency-sensitive nature of this application and amount of data needed, I cannot afford to do network communications to Google server.
I came across OSM this wonderful opensource map data. But as a newbie, it's very unclear how I can extract gps points on roads from OSM. I know roads are stored as "line string" with keyword "highway". Some geojson file includes start and end gps locations for each road. But how do I extract all gps points (Lat,Lng) along the road?
