Claim 14:
15. A method of determining a geographic location from a comparison of an image of an environment with data indicative of a region of earth stored on a data store of a mobile device, comprising:
obtaining the data indicative of the region of the earth,
wherein the data indicative of the region of the earth comprises at least elevation data;
storing the data indicative of the region of the earth on the mobile device;
receiving the image of the environment at the geographic location by a camera;
storing the image on the mobile device;
analyzing the image to determine horizon data indicative of a horizon in the image;
analyzing the image to determine ridgeline data indicative of a ridgeline between the horizon and the camera;
comparing the ridgeline data with the data indicative of the region of the earth to obtain a first comparison result;
comparing the horizon data from the image with the data indicative of the region of the earth to obtain a second comparison result;
determining at least one likely geographic location candidate that matches the environment in the image based on the first comparison result and the second comparison result; and
causing display of the at least one likely geographic location candidate.
