Zusammenfassung:	Systems, apparatuses, and methods are provided for determining the geographic location of an end-user device using a multilateration calculation. The end-user device collects a depth map at a location in a path network. Two-dimensional feature geometries are extracted from the depth map, and a number of control points are identified in the extracted feature geometries. Distances are calculated between the end-user device and the identified control points. Location reference information is received for each identified control point from an external database. A geographic location of the end-user device in the path network is determined through a multilateration calculation using the location reference information of the identified control points and the calculated distances between the end-user device and each identified control point.
