The invention concerns a method and a device for producing a true mapping of a whole zone subjected to a force or a contact (generating a force) from an object passing on or over (or in the proximity, in the case of tunnel study etc ) said zone, in particular an object or a vehicle passing above, or running on one such zone, which consists in: measuring the ground effects optionally by contact, displaying/locating the object, processing the image. The invention is applicable to the effects produced (with or without contact as the case may be) by a tyre, a running tread, a particular aerodynamic element of a land, air or sea craft, such as a wing, chassis and the like of a vehicle, an aircraft wing, a helicopter blade, a train (tunnel or crossing effect), a walker's or runner's, diver's, swimmer's foot, a ship's hull, a tennis ball, a bullet or shell, fingerprinting etc , over the whole area of measurement on or off the ground.
