Preface

Study Group 5B of the International Federation of Surveyors (FIG) was called into existence in 1980 when it became obvious that the work of the huge Commission 5 of FIG could not reasonably be continued without splitting up its activities into several study groups. One of them has become Study Group 5B on "Survey Control Networks". During the Symposium of Commission 5 on "Automated Processing of Surveying Data" in Varna, Bulgaria, 1980, the idea was born to hold a meeting of SG 5B in Aalborg, Denmark.

The plan could be realized at the University Centre of Aalborg from 7th-9th July, 1982. The general subject of the meeting has been dedicated to the quality of networks according to the recommendation of the FIG-Congress in Montreux, 1981, to emphasize the evalutation of control networks under the aspects of stochasticity. The five main topics: Data Processing and Adjustment, Interaction of Stochastic and Functional Models, Quality of Networks, Network Densification, and Optimization of Control Networks, can be seen from this point of view.

The meeting intended to stimulate information exchange among researchers and practitioners. Fifty participants coming from fifteen countries, discussed theoretical and practical problems. The attempt was made to have a good theory applied to a better practice. Moreover, with respect to the XVII. FIG-Congress in Sofia, Bulgaria, 1983, another purpose of the meeting was to clarify the state of art and to work out those points which should be treated with particular emphasis in the next future. As a result, in the closing session the participants agreed to the recommendations listed below. Thus, the meeting functioned as a sign-post: marking the stand-point and showing the direction.

The proceedings have been edited in the most simple way by printing the manuscripts delivered by the authors ready for photo reproductions. This procedure provides a publication as fast as possible.

The meeting itself and the publication of the proceedings was sponsored by Den Danske Landinspektørforening, the Aalborg University Centre and the Hochschule der Bundeswehr München. The organizers are grateful to the sponsors. However the thank of the editors goes particularly to the authors and to all those unnamed persons who directly or indirectly contributed to the meeting which was held in a very competent, friendly and relaxed atmosphere.
