1. A method comprising: receiving a two dimensional image associated with a geographic area or object; receiving a geometry model associated with the geographic area; determining an occlusion weight for a pixel of the geometry model based on the relative height of the pixel to at least one surrounding pixel; generating, by a processor, an embossing map by applying an ambient occlusion range to the occlusion weight, wherein the ambient occlusion range defines a transition area in the embossing map; and generating a composite image based on the two dimensional image and the embossing map.
