Renovation of levelling Network Koper

摘要

In the graduation thesis I analysed the old levelling network of Koper city center, which was first established in the 50s of last century. The network was not complete and also partly damaged, because almost half of the benchmarks do not exist in nature. From the data we got about the levelling network we can see that the accuracy after adjustment was lower than expected.udWith another attempt of adjustment we tried to get better results. We also made a plan of expanded levelling network. From this plan, we measured only the part which covers the city center. Then we stabilized the new benchmarks and made measurements with new and old ones. Afterwards we adjusted the height differences an made topography of the benchmarks . We used the measured heights to establish vertical displacement in city center. udWith renovation of the preserved part of levelling network in the region of Koper, we ensured height in national coordinate system which represented height base for geodetic measurments in center of Koper.ud
