Get Segment/Polyline id from maps - google-maps

Question

Hi i try to find if the google maps or the HERE nokia maps have a static segmentation of the roads and an associated id and where i can find this information. I try to rich information by Rest api from both maps type but i don't find it. Instead with the javascript api i see that i can edit the maps or create, but what i want is to query a server or a database's maps in the way that i can use the latitude and longitude information as key for research (or the address string) and i will get the information from where is the location (so address or lat/long) and in what segment/polyline of the street the location is.
Thanks all!

I think you will need to look at a RESTful API rather than JavaScript:
For the HERE Platform:
To get an address for a Lat/Lng or vice-versa use the Geocoder API
To get an road shapes for a Lat/Lng use the Enterprise Routing API
You will need to register to get access to the documentation, but you can see the APIs in action using the API Explorer e.g. Geocoder Routing
The getlinkinfo endpoint of the Enterprise Routing API could be useful. For example, the URL below ( replace YOUR_APP_ID and YOUR_TOKEN of course)
http://route.st.nlp.nokia.com/routing/6.2/getlinkinfo.json?app_idYOUR_APP_ID&app_code=YOUR_APP_CODEg&waypoint=52.53086,13.3846&linkattributes=shape
Returns the following link info about a line segment:
