Aspects described herein relate to methods and systems for obtaining geographic position data for features that are captured through a device using a relative coordinate system, such as an optical sensor on a vehicle travelling along a route. The relative positions of the features are transformed into geographic positions by first establishing a spatial relationship between the relative coordinate system and a geographic coordinate system. Once the spatial relationship is known, it can be used to match a number of the features captured in the relative coordinate system to features having a known position within the geographic coordinate system, preferably, features that are known to have an accurately measured geographic position. The matched features can then be used as tie points between the relative coordinate system and the geographic coordinate system, and then used to transform unmatched features in the relative coordinate system to positions in the geographic coordinate system.
