The aim of this study was to determine changes in surface area and volume of the Sille dam reservoir, in Turkey, according to the water level. To adopt measures for collecting more water in dam reservoirs, reservoirs and ponds, to prevent water pollution, protect water sources and extend the service life of these facilities, it is important for users (Municipalities, SHW and Irrigation Unions etc.) to know the current topographic conditions and any changes in the storage capacities of these facilities. Sedimentati...

Urban transformation includes the subjects of bringing its function to the places that lost their features, renewing the unhealthy and unlicensed buildings in the city, Transformation of the buildings that might affected from the natural disasters to other using areas, defining the urban functions correctly and planning them, renewing and developing the urban substructure. The aim of the urban transformation is to make the area which is the subject of transformation habitable and make the conditions better. To ach...

The paper describes the automation of astrogeodetic measurements in determining astronomic station coordinates $\Phi$, $\Lambda$ and determining astronomic azimuth A. The automation has been developed at the Faculty of Geodesy, University of Zagreb. The results of precision testing are presented. There are also the applications of automated astrogeodetic measurements in engineering geodetic practice illustrated, first of all those needed for the determination of the surface of astrogeodetic geoid and for independe...

In Republic of Croatia the Law on State Survey and Real Estate Cadastre regulates the maintenance of cadastre and its gradually adjustment to the real estate cadastre, Currently, is in progress the establishment of real estate cadastre by the new cadastral surveys for 5\% of the Croatian territory. For the remaining areas establishment is planned by individual parcel translation. The most important and difficult precondition is cadastral plan geometric accuracy improvement (homogenization). Pursuant to Law Article...

Deformation measurements and analysis are one of the most significant subjects in geodesy. Deformation monitoring and taking precautions on time is very important for safety of people and facilities. In this research, three period measurements were done in a trigonometric levelling network. S transformation and Kalman filtering techniques were performed for detection of vertical deformations. Results showed that both methods determined vertical displacements at the same points. Moreover, the values of velocity and...

The Republic of Croatia, as any other country in the world that has been faced with the war consequences is burdened with one of the most difficult consequences – mine contamination. Therefore the most sophisticated Mine Information System (MIS) has been established in the Croatian Mine Action Centre (CROMAC). Mine Information System of the Croatian Mine Action Centre applied in the system of anti-mine activity in the Republic of Croatia. Geodetic measurements of searched and demined areas is one of the actions ...

Tunnel ’’St. Ilija’’ is on the road that connects the Makarska Riviera and a new highway through the mountain range Biokovo (Figure 1). With a length of 4250 m, it is currently fourth road tunnel in Croatia, but also the tunnel with greatest overburden of 1300 m. According to the available information this is a road tunnel with the biggest limestone overburden in Europe, and as such it represented a real challenge for all who participated in its construction. This article describes the geodetic works that ...

GPS (Local Positioning System) technique is still the most applied positioning system in practical applications and engineering projects in our country and in the world. Since GPS measuring is commonly used in every kind of geodesic study, heights used in practice can be obtained easily in demanded accuracy from GPS. However it is necessary to determine geoid which had enough precision in working place. Because geoid is a natural relation between the ellipsoidal height (h) determined by satellite and orthometric h...

The test network of geodetic base is located at the territory of the park Jelenovac in Zagreb. The test area is rather unstable and suspected of ground subsidence. The geodetic base has therefore been renewed and established for the purpose of monitoring and analysing vertical movements of the geodetic control network. The state of the existing geodetic control points has been recorded and damaged points have been renewed, and destroyed points stabilized anew. The stabilization of points has been made on concrete ...

The Act on protection and conservation of cultural goods has been in force in the Republic of Croatia since 1999. It defines types of cultural goods and measures for their protection and conservation. The main authority for protection and conservation of cultural goods is the Ministry of Culture. This paper will describe geodetic works on saving a protected cultural monument. Results of the analysis of movement measurements over a longer time period will give insight into the real conditions and enable experts to ...

Form time to time real estate owners have problems from each other because of demanding access right from neighbouring real estate which has no bordering to cadastre or reconstruction road. Neighbouring real estate owner doesn’t want to allow the others who want to go their fields, lands or gardens with their vehicles and equipments. According to the Turkish Civil Code Article 747, landlord who doesn’t have enough way from his land to the general road may pay in consideration of demanding an access right from ...

A man-made structure or natural phenomena like crustal movement, vertical land movements, subsidence determination, etc. is subject to deformations due to forces on them. Deformations of a structure require rigorous analysis to reflect significant movements. In general, deformation analysis relies on the reference network that is set outside the deforming area so that a comparison could be possible. However, a geodetic reference network is itself subject to movement. Therefore, the stability of the reference netwo...

Global navigation satellite systems (GNSS) introduced revolutionary changes in the positioning and navigation, but it is well known that the precision, reliability, availability and integrity of the results obtained by this technology, largely depend on the number and geometric distribution of the satellites being tracked. This is especially problem in areas with limited sky visibility, such as urban canyons, dam monitoring in valleys, deep open-pit mines, larges construction sites. Furthermore, indoors or undergr...

Since the geodetic control points are the base for all surveying tasks, the quality of these tasks will directly depend of the quality of geodetic control. The main two elements of geodetic network quality (accuracy) are its precision and reliability. There are different precision and reliability measures for the geodetic control. The positioning precision, as one of the most important component of geodetic network quality, has been expressed in various ways depending on the positioning method. The standards have ...

Operation research is scientific system discipline, that at the same time ranking to the praxeology disciplines – science about rational organization of human activity, applied to the area of management in the economy and in the other areas (research, health care, transport, schools, state administration, urbanism, cosmic research, army, etc.). Operation research is orientated to the operation of production, transport, division, services, supplying, stocking, renovation, development, conflict solving, etc. Many ...

One of the most important factors in economical development is using the resources efficiently. Land possession has a special importance in agriculture which is one of the main sectors of economy. Land is a limited and needed resource which is impossible to reproduce. On the other hand, many scientists explained that agricultural lands have been reduced day by day. For that reason it is necessary to make every kind of regulations and implantations for efficiently and fertile use of lands. One of the most important...
