A method for acquiring images of the surface of the earth, installing an aerial platform in a quasi-stationary position, equipped with an image acquisition system with a large field of view and a second, high-resolution, image acquisition system is disclosed. The method includes implementing successive observation cycles, each one including the acquisition of an image of a zone of interest by the first system, the partitioning of the image thus acquired into mesh units which each correspond to a sector of the zone of interest, the analysis of the image in order to detect the potential presence of unwanted marks, and the acquisition of an image by the second system for the mesh units for which no unwanted marks have been detected. Observation cycles are thereby implemented until images of the entire zone of interest have been acquired by the second system.
