The methods and/or systems described in this disclosure enable the registration (fusion) of multi-modal images of a scene (700) with a three dimensional (3D) representation of the same scene (700) using, among other information, viewpoint data from a sensor (706, 1214, 1306) that generated a target image (402), as well as 3D-GeoArcs. The registration techniques of the present disclosure may be comprised of three main steps, as shown in FIG. 1. The first main step includes forming a 3D reference model of a scene (700). The second main step includes estimating the 3D geospatial viewpoint of a sensor (706, 1214, 1306) that generated a target image (402) using 3D-GeoArcs. The third main step includes projecting the target image's data into a composite 3D scene representation.1/15 100 START 1023 _ _?
