Abstract

Mestna nivelmanska mreža Piran je bila vzpostavljena sredi petdesetih let prejšnjega stoletja. Nova izmera se je začela zaradi še nepreračunane in neizravnane mestne nivelmanske mreže Piran, ki bi se sicer morala izvesti v sklopu sanacije nivelmanskih mrež leta 2000. V bližini vodomerne late, ki jo je postavila Agencija RS za okolje na pomolu v Piranu, je bil stabiliziran nov reper, ki bo povezan z mareografsko postajo Piran, ko bo zgrajena. V novo izmero so bili vključeni tudi vsi še ohranjeni reperji. V sklopu diplomske naloge smo z metodo geometričnega nivelmana izmerili višinske razlike med tremi obstoječimi reperji. Merjene višinske razlike smo popravili za vpliv temperaturnega popravka, metra para nivelmanskih lat in razlike pet nivelmanskih lat ter nivelmansko mrežo izravnali. Rezultat so izravnane nadmorske višine reperjev s pripadajočimi natančnostmi v višinskem datumu Koper in a posteriori ocena natančnosti merjenja višinskih razlik. Na koncu smo dobljene nadmorske višine primerjali z višinami iz topografij in izračunali razliko višin, določenih v višinskih datumih Koper in Bakar.

Secondary title:	Measurement of the Piran Levelling Network
Secondary abstract:	Piran town levelling network was established in the mid-1950s. A new measurement began due to the lack of calculated and levelled Piran town levelling network which should have been implemented within the restoration of the levelling networks in 2000. In the vicinity of the tide staff placed by ARSO on the pier in Piran, new benchmark was stabilized which will act as a mean for connection of the Piran tide gauge station when constructed. The new measurement also included all of the preserved benchmarks. Within the graduation thesis, we used the method of geometric levelling in order to measure the height difference among the three existing benchmarks. Height difference measurement was corrected for influence of the temperature correction, meter of a pair of levelling staffs and a difference of five levelling staffs, and we levelled the levelling network. The result of the levelling are levelled altitudes of the benchmarks with the corresponding accuracies in the Koper vertical datum and posteriori estimates of the accuracy of measuring altitude differences. At the end, we compared the obtained altitudes with the altitudes from topographies, and calculated the difference of heights set in the vertical datum of Koper and Bakar.
