I am searching for the way to identify lat/lng coordinates of street intersections of, for example, city blocks in specified area. Previously, I tried to utilize the data from OpenStreetMap to do this, but it is not working well. (Please refer to my previous question: "How can I exhaustively collect latlng coordinates of street intersections from OpenStreetMap (or from any other data)?")
I was searching for the alternative method, and I found that Google Places API seems to offer the data I want. In the following page (link), Google says that it supports the Place Type "intersection". I tried the following url to access their API (with replacing MY_API_KEY with my Google API key),
but no luck, it returned
{ "debug_info" : [], "html_attributions" : [], "results" : [], "status" : "ZERO_RESULTS" }
I was wondering why this is not working. Is it because I am in the area that the service is not supported (the area I specified above is in Washington D.C.), or am I making some mistake in the query? Is there any walk around to this or do you know better way to find the street intersection coordinates?
Thanks.
