Abstract
The invention is directed to a coordinate measuring apparatus which includes an elevation measuring device. The elevation measuring device is connected with a stationary granite table via one or several linkage arms for determining the planar coordinates. Transducers for detecting angular values or pull-out lengths are arranged with respect to the joints or pull-out members of the linkage arms from which these planar coordinates can be computed by a computer. A method of determining the coordinates is also disclosed.
