summary This paper presents an experiment using digital photogrammetry for the restitution of urban forms, using precise and low cost techniques, an alternative solution for the cartographic actualization of cities. The technique uses digital cameras (non-metric), with resolution compatible with the precision and scale required for the products. This process simplifies the acquisition of the photos, that can be taken by different places: in the ground, in the top of high buildings or by small airplanes or ultralights, in opposition of the traditional image acquisition method, done by costly aerial photogrammetric flights, realized by specialized companies.
