For simplification of storage of measured range and direction values in surveying, as well as for coordination and processing of these values with additional information these values are transmitted from the measuring station (1,2) to the target point (2'). The additional information is mainly obtained at the target point (2') at a distance from the measuring station (1,2) and at the other end of the measured range, whereas the measured values are transmitted by modulating electric signals upon the infrared beam of an electrooptic range-finder (2) or by means of a separate short wave link. At the target point (2') there are a signal receiver and a programmable data storage device (3) which accepts the additional information keyed in by hand via a keyboard (17). Advantages are obtained by this method in simplifying the observer's task and preparation of reports, providing automatic data transmission and therefore reducing reading and transmission errors. |
