Abstract: Method for selecting stereo pairs of satellite or aerial images to generate elevation data for an area of interest, the method being computer-implemented and including a phase of selecting eligible stereo pairs from an initial set of images representing the area of interest, followed by a phase of ranking the selected stereo pairs according to their quality. The method further includes a phase of defining N image clusters, where N is an integer greater than or equal to 2, each grouping images from the initial set according to a similarity criterion, and a phase of selecting the best stereo pairs per cluster on the basis of the ranking established during the ranking phase and on the fact that a pair belongs to a cluster if the two images of the pair belong to the cluster.
