Jubilee Seminar: 25 years of Motorised Levelling

Geodesy & Surveying in the Future

The Importance of Heights

March 15-17, 1999 Gävle, Sweden

3rd Circular Letter

Sponsored by:

International Federation of Surveyors (FIG)
Commission 5

Nordic Commission of Geodesy (NKG):
Height Determination Group

National Land Survey of Sweden (NLS):
Geodetic Research Division

Who should attend?

The technical evolution goes more and more to automated Robotized Real Time surveying techniques using different kind of instrumentations. The geodesists, surveyors, teachers, students and others dealing with surveying have to face many problems in their work. Different solutions are accessible to do this work but to achieve it in the best we need much more knowledge and developments in this field.

This seminar will give a very deep information about the possibilities and limitations existing today and a look in the future. It will be of a great help for every one when dealing with these questions. The seminar will focus on questions concerning height determination

Workshop topics

bulletHow can we help the surveyor in his daily work, today and tomorrow?
bulletModern techniques for height determinations as GPS, INS, and Digital Levels.
bulletReal Time Kinematic heighting as Robotised and Motorised Levelling Techniques (ML, MTL, RPLS etc.).
bulletComputation techniques and analysis of results.
bulletReference Frame and Systems. Transformations between different height system.
bulletOngoing national and international projects.
bulletQuestions about the future levelling networks. 1D or (2D+1D).
bulletConnection to tide gauges.
bulletAccuracy limitation factors in height determination.
bulletCalibration of instruments. Guidelines and standards
