1. A method of determining geographic information for a location of capture of an image using an image-based georeferencing system comprising one or more processors, the method comprising: receiving a first image at the one or more processors of the image-based georeferencing system, the first image captured by a camera at the location of capture, the first image comprising first digital image information representing a plurality of reference features; identifying, with the one or more processors, a cataloged second image comprising second digital image information representing the reference features, wherein the first digital image information is different from the second digital image information; automatically determining, with the one or more processors, the reference features common to both the second digital image information and the first digital image information; accessing, with the one or more processors, georeferenced location information for the common reference features, wherein the georeferenced location information is associated with the second image, wherein the georeferenced location information is accessed from a geographic information system (GIS) repository, and wherein the accessed georeferenced location information is not represented by information representing an image; determining, with the one or more processors, geographic location information for the location of capture at least partly based on the first digital image information and on the accessed georeferenced location information; and providing the geographic location information for the location of capture to a user.
