A telemetric spacial data recorder for the elaboration ofa floor plan is described herein. The telemetric spacial data recorderincludes a base module, a remote module, a hand held module and adata acquisition device. The distances between (a) the base module andthe 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 aremeasured by electronic distance measuring devices. Similarly, the anglerelations between, (i) the base module and the remote module, (ii) theremote module and the hand held module and (iii) the hand held moduleand the target point of a physical object are measured by electronic anglemeasuring devices. The measurement devices are linked to the dataacquisition device which makes a geometrical construction to determinethe relative spacial position of the target point of the physical surface withrespect to the spacial position of said base module. According toanother embodiment of the present invention there is provided atelemetric spacial data recorder including a remote module, adisplaceable module and a data acquisition device. Again, distances andangles are measured and supplied to the data acquisition device thatcalculates the relative spacial position of a target point with respect to theremote module.
