The paper presents such a method of distribution of observations in a surveying network, which allows to meet requirements concerning the network with the possibly lowest direct costs of survey. As a result, a set of azimuths, sides, angles and GPS chords which can be measured in a given network is obtained; then the selection of a subset, which meets the above criteria may be performed. The OPTY98 computer system, which time of calculation may be accepted by an arbitrary network, has been developed for the proposed algorithm. Required data as well as obtained results are presented using the example of the Refe network.
