How to query Overpass Turbo through Java within an Android Native Activity to determine classification of highway?

I am trying to build a an android application that can determine the type of highway the user is on by latitude and longitude coordinates. Is there a way to query overpass turbo to retrieve the type or classification of highway ?(whether it is motorway, trunk, primary, secondary, tertiary or residential) I was not able to find any relevant tutorials or documentation to do so. Can I implement a query in a Java class method as described below: 

LocationManager lm(LocationManager)getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
@Override public void onLocationChanged(Location location)
{ 
double longitude = location.getLongitude();
double latitude = location.getLatitude(); 

/*query overpass turbo to classify highway*/
/*store retrieved classification type as a string*/

}

And instead of fetching all ways tagged as highways around the given coordinate, can the current position be identified as to whether the way is which type of highway?

Solution

  • You need to look for ways with a highway tag. You can use the following Overpass API query to locate all ways tagged as highway within 100 meters of 51.033,13.749 (lat, lon):

    [out:xml][timeout:25];
way(around:100,51.033,13.749)[highway];
out body;
>;
out skel qt;

    You can see the result on overpass turbo or download the results directly via Overpass API.

    You can use the last link for building a simple HTTP request from within your application. Note that Overpass API supports different output formats such as XML and JSON, depending on your query.
