Author : V.Moca, H.I. Hoga?, O.Radu, M.Macovei |
Abstract | Full Text |
Abstract :The implementation of cadastre and cartographic products was generated by the society’s needs to develop, themeasurement technologies and the concept of graphic representation. The present case study includes a synthesis of the cadastraland cartographicworks that were conducted during three different historic periods: 1918 -1950, 1951 -1989 and 1990 -2018. Cadastre was first established in Greater Romania on January 3rd, 1919, based on Decree no. 3922 that stipulated the organization of “Central Office for Cooperation and Apportionment of Propriety to Peasants”. Within this new created institution it also functioned the “The Department of Cadastre and Technical Works” that was responsible with the implementation of the general cadastre. In the present stage, ithas passed on to the execution of systematic cadastral works estimated to be conducted between2015 -2023. These works are financed by the National Agency of Cadastre and Real Estate Advertisement and are conducted by specialized professionals according to the official legislation and technical provisions in force. |

Author : I. Agapie (Mereu?a), M.Luca, L.Crenganis, G. Nantu |
Abstract | Full Text |
Abstract :In the inventory process of real estate we use programs such as: Autodesk Autocad, ArcMap 10.2, Microsoft Office Excel, online platform ArcGIS, DDAPT aplication etc. This paper presents a way to develop a database needed for land inventory in the county Vaslui, town Murgeni, village Floreni. For the area of study, so far, has been made a series of queries through which we highlightedlands that has not received title deeds from the total of the existing ones. The operation is efficient and with high efficiency. The desired results were also achieved by developing thematic maps representing the cadastral plan of the studied area on cadastral sectors, categories of land use, construction destinations and tax on land value ranges. The work consisted of drawing the digital cadastral plan in Autocad, and afterwards the plan was imported into ArcMap, where the graphical database was correlated with the alpha-numeric one. Subsequent, was created an account on the ArcGIS-online platform to import, display, and use the database. This method can be further develop by including other items of interest, such as public utility networks (water -sewerage, heating, electrical, telephone, gas, roads) |

An Overview on Space Time Cube Visualization in GIS |
Author : A. C. Badea, G. Badea |
Abstract | Full Text |
Abstract :Over the last years, the STC(Space Time Cube)visualization method has been analyzed in many scientific papersin the literature. The term STC cames from cartography, meaning a geographical representation where time is treated as the third dimension.This model was introduced by the Swedish geographer Hägerstrand at the end of the sixties. When datasets involve more than one dimension in addition to time are difficult to visualize. In a geovisualization environment, maps as digital representations are used to emphasize visual thinking about geospatial patterns, relationships, trends. Currently, GIS technology offers dedicated tools that lead to interesting viewing results using this method, the cube and its contents being automatically created from a database.We reviewed some functions ontemporal data, usedto view geospatial data sets in differentways.Also in the case study, an earthquake dataset was used, which was represented using the STCmethod, but also in the form of a temporal slider application. |

The Role of Models in Cadastre |
Author : I. Botnarenco, E. Zubco |
Abstract | Full Text |
Abstract :The practice of cadastre implementation in the Republic of Moldova made us face an objective reality that later became a scientific issue -the models in the cadastre. This reality has its arguments. It took place in the post-soviet countries.For a long time in the post -soviet countries, the cadastre developed in the conditions of lack of private land ownership, under the conditions of the state monopoly on property. Particular attention was paid to the protection of land resources.In other countries of the EU, the cadastre was developed having the main purpose of protecting land ownership and implementing economic policies.Having different objectives, the reality has given rise to two models in the cadastre which, at the current (contemporary) stage, complete positively one another. At present, all three objectives are up to date for the society.The present study aims to highlight the points of tangency in the content of cadastral models in order to enrich the world cadastral concept by eliminating those negative aspects that cannot be successful for various reasons. |

Comparative Analysis of Specific Deformations Geodetic Reference Systems in Romania |
Author : F .M. Brebu, A. C.Bala |
Abstract | Full Text |
Abstract :Based on the theories of Ptolemy emerge so far and Romania various systems cartographic projections: Stereographic 1930, Stereographic 1970or Universal Transverse Mercator, which are used today.Each of these cartographic projection systems presents both advantages and disadvantages.Analyzing the deformations in the main cartographic projections in our country, using a generic program of transformation of geospatial coordinates from one CRS to another, we can obtain visually appropriate interpretations and make statistics, with the possibility of the percentage, the advantages ofusing one or the other.Based on the above-mentioned criterion, the scientific paperaims to present the implications from the point of view of the linear deformations, which each of these projections generates, as well as a comparative analysis between them, more suggestively, the advantages of cartographic representation in each case. |

Study of the Inclinometer Calibration Method using Geodetic Measurements |
Author : M. Iacob, V. Chiriac, V. Ciclicci |
Abstract | Full Text |
Abstract :The inclinometer is used for small-angle measurement and can be fixed on the radio-communication tower to obtain changes relative to the construction’s vertical plane. The real inclination of the tower can be calculated by modellingthe variables obtained from the inclinometer in combination with geodetic measurements. In order to perform assembly error calibration a precise mathematical model based on inclinometer data and total station measurements is proposed. For experimental measurements a dual axis inclinometer and a reference prisms installed on the rigid platform were used. Finally, through simulations of various inclination of the platform, the calibration method is validated and the inclinometer measurement accuracy is evaluated. The preliminary results show the possibility to use this calibration method in order to determine initial position of the inclinometer installed on the tower construction |
