CA 2719928

An illustrative embodiment of a computer-implemented process for projecting geographic coordinates into a coordinate space of a target image enabling navigation of the target image is presented which performs an initialization using a set of geographic reference points, receives a set of points in a coordinate space of a target image, receives a one-to-one mapping between the set of geographic reference points and the set of points in the coordinate space of the target image, computes a triangulation of the reference points of each respective set of reference points, identifies a containing triangle represented in the triangulation in which an arbitrary geographic coordinate point is located, identifies points in a space of the target image corresponding to vertices of the containing triangle, interpolates a location within the containing triangle to form a resulting location and superimposes the resulting location onto the target image.
