Comparative Analysis Regarding GIS Interpolation Methods in the Problems of Spatial Analysis and Obtaining MDT |
Author : I. Agapie (Mereu?a), L. Crengani?, D. Mereu?a, M. Luca |
Abstract | Full Text |
Abstract :Interpolation methods are essential tools for generating the Digital Terrain Model (MDT). Making a comparison between different interpolation methods in the GIS environment, by using the Geostatistical Analyst function, will indicate the degree of accuracy of each method. The quality of the Digital Terrain Model (DTM) depends on the accuracy of the measured data, the techniques and software used in the measurement processing stage. In this paper, three interpolation methods available in ArcGIS software are analyzed: Inverse Distance Weighted (IDW), Local Polynomial Interpolation (LPI), and Kriging. Two scenarios were considered in the study: in the first, an area with a steep slope was analyzed, in the second scenario, a gently sloping area was analyzed. The techniques for performing topographic measurements were of the modern type, respectively the current use of satellite technology. Measurements for both scenarios were performed using GNSS technology and the RTK method for determining point coordinates in real time. The location of the studied areas is in Ia?i county, Miroslava commune. |

The Development of a Geospatial Database Regarding the Calculation of Land Taxes and Duty System |
Author : C.M. Cîmpean |
Abstract | Full Text |
Abstract :Any property owner in Romania have to pay an annual tax for it but also exemptions are applied depending on title deed specifications and other special circumstances.
Current Romanian tax and duty system was influenced by adhesion to European Union. For our country to be able to adhere to EU a change to fiscal Code was necessary to comply with other state members.
Aim in Romania is to improve the capacity of revenue collections for state budget in the shortest period of time to fulfill priorities without influencing the public finance system in the medium and long term, so that the Romanian state can manage risks or unforeseen situations.
Specialized programs are currently implemented in Romania to support with automatic tax and duties calculations for ongoing and previous years. Debiting can be done through notification and automated invoicing to taxpayer or documents can be issued automatically according to the legal forms. |

Dacian Fortress Apoulon - Historical-Cartographic Convergences |
Author : M. Salcudean |
Abstract | Full Text |
Abstract :In this paper, systematic archaeological research was approached in order to build in the GIS environment the altimetric numerical models of the lands subject to archaeological research at the Apoulon Fortress. The research at the Apoulon Dacian Fortress began in 1960 and were started by Gh. Anghel, and the data used in the project were taken topographically in the 2005, 2006 and 2007 campaigns. The database created is constantly used by researchers in order to arrange, preserve or rehabilitate the archaeological heritage and historical monuments and therefore must always be updated. The use of modern GNSS and GIS technologies was used to take over and process the information from the field. The advantages of this systematic research would benefit both the institutions dealing with real estate in our country and the public interested in research and the history of discoveries. |

Abstract | Full Text |
Abstract :In recent years, social networks have become more and more influential in the daily lives of people of all ages. People ask, inform themselves and express their opinion much more freely than in the past.
Therefore, public administrations, both local, county and national, have understood the importance of their presence on social networks and try to maintain, at least to a certain level, the relationship with citizens, publishing various information of interest about their activity.
The present paper is intended to be a critical analysis, based on various real cases, of the communication of information to citizens published by local public administrations. The main purpose of this analysis is to highlight the importance of using visual communication in the transmission of information.

Research on the Topology of Earth Dam by using GNSS Technology |
Author : M. Luca, I. Agapie (Mereu?a) |
Abstract | Full Text |
Abstract :Monitoring and assessment of the operational safety of hydrotechnical constructions made of earth and local materials requires geodetic measurements at specified intervals. Among these hydrotechnical constructions are the earth dams which have many negative events. A high percent of accidents in Romania occur at small earth dams. Monitoring the topology of earth dams is done by classical geodetic methods. But, in recent times, new technologies have emerged to track the topology of earth dams, of which GNSS technology stands out. Research conducted with GNSS technology, to monitor the geometric parameters of a dam in the Moldova area, has highlighted the reliability of the method by the accuracy of the results and reduced working time. Fild research conducted at the Podisu Dam in Iasi county, in conjunction with documentary studies on the evolution over time of the topology of the earth dam showed important changes with an influence on the stability of the construction. Interpretation of the data obtained by measurements showed a change in the geometric shape in the horizontal plane and in cross sections. The method of measurements performed using two GNSS receivers was used in the research. |

Considerations on the Use of Geodetic and Satellite Methods in the Study and Monitoring of Building Behaviour |
Author : G. Nistor, C. Onu, C.I. Gre?i?a, D. Padure, M. Diac |
Abstract | Full Text |
Abstract :Two groups of methods are being used during the complex process of studying the behavior of the buildings: physical and geometrical methods. Within the first group of methods, the setting up of the instruments is made directly inside of the studied building moving thus together with the latter and revealing this the relative values of the deformations. The second group containes the geodetic and photogrammetric methods by whose mean we are determinating the position of some fixed points of the buildings, with reference to the immobile points which are positioned around the building, being this able to obtain the absolute values of the de formations and displacements of the considered building.
The use of the geodetic and photogrammetric methods do not exclude the use of the physical methods, more than they are strongly related and completing one another.
Within this paper are made some considerations concening the use of the geodetic methods for studying the behaviour of the buildings, presenting the fact that these methods are representing a fundamental system within the experimental and in situ studying process, and that these methods cannot be replaced.
Due to the high precision of the measurements and estimating of the accuracy of the results, the geodetic methods ensure the obtaining of the most realiable values of the parameters characterising the state of stress and deformations of the buildings.

Author : A.P. Gradinaru, A.C. Badea, P.I. Dragomir |
Abstract | Full Text |
Abstract :In order to obtain accurate 3D City Models, some of the most important steps are geospatial data acquisition and the processing of this data. Aerial laser scanning (LiDAR-Light Detection and Ranging) is one of the most used methods of data acquisition and the main concern is classifying the point cloud in order to assign a class to each point. The classes of interest for 3D city models are the ground, buildings and possibly the high vegetation class which may interfere with the buildings. In this article, we aimed to highlight the main steps that are necessary to classify LiDAR point clouds. We chose two software products, one developed by Bentley – Microstation Terrasolid Suite and the second by Esri – ArcGIS Pro. |
