Geodetic works in research and development plan in remediation of landslide Kostanjek

Modern surveyors play an important role in the field of disaster and risk management. Nowadays in most cases results of their measurements take part in a multidisciplinary study. Projects main idea was realized during 2011 and 2012 within the frame of scientific Japanese-Croatian project and will be continued. According to the previous studies landslide Kostanjek is the largest active landslide in Croatia and since its activation in 1963, it has caused substantial damage to local infrastructure. Different surveying methods were implemented in several phases. In each phase, survey method and required accuracies, were adjusted to the needs of further research. It is significant that the results obtained using different surveying methods has showed important role of geodesy in managing high-risk areas such as landslides

Integracija mjernih sustava, napredno kodiranje i atributiranje uz sinkronizaciju terena i ureda

Integracija GNSS-a i mjerne stanice, primjena kodiranja i atributiranja te sinkronizacija terena i ureda predstavljaju inovacije u geodetskoj praksi. Napredovanje tehnologije neminovno utječe na tehnike izvođenja geodetskih radova. U svrhu praktične primjene istih, obavljena je terenska radionica izmjere dijela Studentskog doma dr. Ante Starčevića. Predstavljene su pojedine mogućnosti kojima se povećava produktivnost, skraćuje vrijeme izvođenja terenskih radova, pojednostavljuje obrada podataka itd., a uz očuvanje kvalitete podataka. Iako nove tehnologije nude mnoga poboljšanja, od svih sudionika se, kao i uvijek, zahtijeva stručan i odgovoran pristup
