Abstract: A telemetric spacial data recorder for the elaboration of a floor plan is described herein. The telemetric spacial data recorder includes a base module, a remote module, a hand held module and a data acquisition device. The distances between (a) the base module and the remote module, (b) the remote module and the hand held module and (c) the hand held module and a target point of a physical object are measured by electronic distance measuring devices. Similarly, the angle relations between, (i) the base module and the remote module, (ii) the remote module and the hand held module and (iii) the hand held module and the target point of a physical object are measured by electronic angle measuring devices. The measurement devices are linked to the data acquisition device which makes a geometrical construction to determine the relative spacial position of the target point of the physical surface with respect to the spacial position of the base module.
