Abstract
A system described herein includes a text extractor component that extracts text from a digital image and a determiner component that automatically determines whether or not the digital image is a map of a geographic region based at least in part upon the extracted text. The system additionally includes a correlator component that generates correlation data that causes the digital image to be correlated with a portion of a reference map that pertains to the geographic region if the determiner component determines that the digital image is a map of the geographic region.
