Abstract: Embodiments include a system and a method for determining a geographic location corresponding to pixels in a scan. For a scan of an area including a plurality of pixels, measurements of at least one physical property may be received. An embodiment may include identifying in the scan at least a first pixel and a second pixel corresponding to known at least a first and a second geographical locations; creating a set of pixel values vectors, for each pixel values vector calculating a correlation factor between the pixel values vector and a vector that includes the measurements; selecting a pixel values vector, from the set of pixel values vectors, for which a correlation factor higher than a threshold value was calculated; and determining the actual geographic location of the area represented by each pixel in the selected pixel values vector based on the known geographic locations.
