RHB 70 is not a height system in the true sense, but rather a densification and to some extent a remeasurement of RH 70.
New heights from the third precise levelling
RHB 70 is the designation for heights that have been calculated in the system RH 70, but with new measurements of high quality from the third precise levelling campaign.
The calculation was made step-by-step in connection with the third precise levelling going forward. The purpose of these calculations was to be able to quickly spread new heights and good connection points to users of local height networks. As the third precise levelling programme took 25 years to carry out across the country, many users did not want to wait for the new national height system, RH 2000.
These calculations used stable benchmarks from the second precise levelling with heights in system RH 70 as fixed. The calculations are thus performed in system RH 70, but the term is used to indicate that the heights come from measurements in the third precise levellling, and should not be confused or mixed with older, often bad, RH 70 heights.
