Validation and Preparation of Data for the Computation of a New Height System in Sweden

摘要

The production work in the third precise levelling of Sweden is now completed after 25 years. Some 50 000 km has been levelled using the motorised levelling technique, and some 50 000 new benchmarks have been established. A lot of effort was put in to the project in the beginning to create a digital production line and the same production line as well as measuring technique has been used throughout the project. The main task now is to work towards the creation of a new height system in Sweden.
