1. A mobile device configured for augmented reality comprising: an image capture device operable to capture an image of a real scene; a location sensor operable to determine the geographic location of the mobile device; an orientation sensor operable to determine the orientation of the mobile device; and a processor operable to: determine a pointing vector directed towards the real scene from the orientation of the mobile device; receive wireframe geometry data over a wireless communication link from an enterprise server storing digital data defined on a digital coordinate system, the received wireframe geometry data corresponding to a predetermined area surrounding the geographic location of the mobile device; filter the received wireframe geometry data to a region aligned on the pointing vector, the region being smaller than the area surrounding the geographic location of the mobile device; and register the filtered geometry data onto the image.
