A method and system for locating a high-intensity target light source (26) from an elevated observation location (Po), for instance in an aircraft. The target light source is located at/near an earth surface portion (30) and amongst reference light sources (16, 24, 25) arranged along the surface portion. This target light source emits light (28) with a peak radiant intensity that exceeds the intensity of the reference light sources by at least one order of magnitude. The method includes:acquiring, with an image recording device located at the observation location, images of the light and light emitted the reference light sources;comparing the images and a digital ground map (50) that includes representations of the surface portion and of structures (20, 22) associated with the reference light sources, andestimating a location (Pt) of the target light source relative to the reference light sources, based on the comparison.
