Claim 9:
10. A system for determining a geographic location from a comparison of an image of an environment with data indicative of a region of earth stored on a mobile device, the system comprising:
a camera for generating the image of the environment;
a data store for storing the image and the data indicative of the region of the earth;
one or more processors; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when processed by the one or more processors, performs a method of determining the geographic location from the comparison of the image of the environment with the data indicative of the region of the earth stored on the data store of the mobile device, the method comprising:
obtaining the data indicative of the region of the earth,
wherein the data indicative of the region of the earth is a subset of a global data set,
wherein the global data set is indicative of a plurality of regions 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 the camera;
storing the image at the data store on the mobile device;
analyzing the image to determine horizon data indicative of a horizon in the image;
determining ridgeline data indicative of a ridgeline between the horizon and the camera;
comparing the horizon data and the ridgeline data from the image with the data indicative of the region of the earth;
determining at least one likely geographic location candidate that matches the environment in the image based on the comparison; and
causing display of the at least one likely geographic location candidate by the mobile device.
