1. A method for determining the quality of civic address produced by reverse geocoder, the method comprising:
receiving, at a node, a request by a public safety answer point (PSAP) for a civic address corresponding to user equipment (UE) initiating a call for emergency services;
comparing, by the node, a geocoded location corresponding to the UE to a geodetic location corresponding to the UE to determine a distance between the geodetic location and the geocoded location, the geodetic location having an uncertainty;
based on the uncertainty of the geodetic location and the distance between the geodetic location and the geocoded location, determining a quality of the civic address; and
based on the quality of the civic address satisfying a configurable threshold, providing the civic address to the PSAP, the civic address being the geocoded location.
