Claim Text:
1. A computer-implemented method for determining three-dimensional positions of features, comprising: receiving, by one or more computing devices, data associated with a plurality of images, wherein each of the plurality of images covers at least a portion of a geographic area; detecting, by the one or more computing devices, features contained within the plurality of images; determining, by the one or more computing devices, a plurality of matched features based on a comparison of the detected features contained within the plurality of images; selecting, by the one or more computing devices, a subset of the plurality of matched features, wherein each respective matched feature of the subset is selected based at least in part on a quantity of other matched features in proximity to the respective matched feature; and determining, by the one or more computing device, three-dimensional positions associated with one or more of the matched features included within the selected subset.
