1. A method, comprising:
estimating, by a system comprising a processor, an azimuth of a cell associated with a base station based on a first analysis of validated location data associated with a validated cell location of the cell and respective location data associated with respective locations of respective devices of a group of devices associated with the cell, wherein the azimuth is an estimated azimuth;
determining, by the system, whether a recorded azimuth of the cell is validated based on a second analysis of estimation data representative of the estimated azimuth of the cell and recorded data representative of the recorded azimuth of the cell, wherein the recorded azimuth of the cell that is validated is usable to facilitate enhancing accuracy of determining device locations;
receiving, by the system, a request from a dispatch system for location information for a mobile device; and
responsive to determining that the mobile device is communicatively coupled to the cell associated with the base station:
determining, by the system, the location information for the mobile device according to the recorded azimuth of the cell that is validated; and
transmitting, by the system, the location information for the mobile device to the dispatch system.
