Per angusta ad augusta. A történelmi atlaszokról. Donald Matthew: A középkori Európa atlasza. The Times Atlasz. Világtörténelem. Történelmi Világatlasz

Author(s): József Laszlovszky / Language(s): Hungarian Issue: 03/1993

A történelmi atlaszok készítése hosszadalmas, aprólékos kutatómunkát igénylő feladat. Egyszerre sokféle követelménynek kell megfelelni, hiszen együtt kell szem előtt tartani a történelmi szakmai szempontokat, a térképkészítés törvényeit és a képi megjelenítés vizuális lehetőségeit. Jó történelmi térkép készítése nem egyszerűen azt jelenti, hogy ismert történelmi eseményeket vagy folyamatokat atlasz formájában is bemutatunk. Önálló kutatásokat kell végezni ahhoz, hogy el lehessen dönteni, vajon milyen időszeletekben megrajzolt állóképek, máskor dinamikus fejlődési képek reprezentálják legjobban a történelem egyes korszakait.

Information System of the Real Estate Cadastre in the Republic of Moldova

Author(s): Ion Botnarenco / Language(s): English Issue: 21/2016

The Information System of the Real Estate Cadastre, which exists in the Republic of Moldova at present, was developed in early 1990s together with the process of launching for a reform of land relations. This is the period which is thought to be the peak of the economic crisis. The policy based on the state’s land monopoly failed.This study includes a detailed analysis of the cadastral process and the role of the information system of land cadastre as a key component of this process. Therefore, it is important to determine the objective of the cadastral process. There is no use to study the content of cadastre if you have no idea about the reasons the process occurs as well as fundamental social and economic problems that should be resolved in cadastre. It is also important to evaluate the multifunctional aspect of cadastre and its interaction with other processes in the society.Having analyzed the cadastral process development in the Republic of Moldova and cadastral information systems of other countries, we suggest that our cadastre should be modified. The question “Which way should we choose?” becomes more and more relevant for the Republic of Moldova. Which direction would be closer to social and economic policies implemented in the Republic of Moldova? The fiscal policy has an important role in determining the cadastral model as it affects the economy as a whole.

Deformation Analysis in Case of Concrete Dams

Author(s): Silvia Alexandra Dreghici / Language(s): English Issue: 21/2016

Rigorous methods of displacement and deformation analysis need a relatively large volume of computations. In many cases, including concrete dams, the detection of displacements and deformations in a short time may help preventing any negative effects on monitored objectives and the environment. Therefore, we must understand, determine, and monitor the factors that may cause building deformations and, if case, take the corresponding measures in order to prevent any negative effects on the observed building. Mainly because of their role, concrete dams are included into the most important class of buildings that need to be monitored. In the paperwork, I chose as a case study the Tau Dam, included into Şugag-Tău Hydropower Complex, built on the Sebes Valley, Alba County, Romania.

Aerial Survey Test Project with DJI Phantom 3 Quadrocopter Drone

Author(s): Tamás Jancsó,Peter Engler,Peter Udvardy / Language(s): English Issue: 21/2016

The paper deals with the optimization of the aerial triangulation based on UAS images. The images were taken with a DJI Phantom 3 quadrocopter and they were measured in Photomod Lite ver. 4.4. The bundle adjustment was carried out twice; first in Photomod Solver and later in BINGO ver. 6.8. During the adjustment 14 ground control points were used and 31 points were calculated as new points. Using these new points we could compare the coordinates to the coordinates received from the high-precision field surveying measurements. From the coordinate differences the calculated RMS errors of horizontal coordinates are around one pixel size on the ground and to 2.5 pixels vertically. The final results showed us that a non-metric camera at low flight height with a quadrocopter can be used effectively and accurately at aerial surveys of relatively small areas.

Author(s): Isabela Balan,Loredana Crengăniș,Flaviana Corduneanu / Language(s): English Issue: 20/2016

Between the 11th and 13th of September 2013 large quantities of rainfall occurred in the upper catchment of river Geru. The precipitations have generated a flash flood with three peaks, with the maximum discharges of 118.00 m3/s recorded on 12th of September 2013, 2300. Simulations of the flash flood were performed alternatively with Mike 11 by DHI - NAM (Nedbør Afstrømning Modele) and with MIKE by DHI –UHM, using radar precipitations as input data. Radar rainfall values were generated by ROFFG (Romanian Flash Flood Guidance) software system in ArcGIS module for determining the area affected by flash floods.The program Mike 11 by DHI – NAM accounts for the water content in up to 4 different storages. As default, NAM uses 9 parameters to represent the Surface zone, Root zone and the Ground water storages. The program Mike 11 by DHI – UHM calculates excess rainfall and determines infiltration losses by four methods. The discharge hydrographs simulated with Mike 11 by DHI program were compared to the discharge measured at the hydrometric station. The amplitude and phase errors are directly dependent of the accuracy of the input data and chosen parameters.

GIS Based Automated Valuation Models – A Genuine Solution for Real Estate Valuation in Romania

Author(s): Gabriela Droj,Laurentiu Droj / Language(s): English Issue: 20/2016

In the latest period, the usage of statistical models in the valuation of real estate properties became very popular among appraisal specialists, bankers and researchers from this field. Many Automatic Valuation Models (AVM) using different statistical and mathematical models like regression, neural networks, and fuzzy logic were proposed and developed with the purpose of assessing the value of a property. Also Computer-Assisted Mass Appraisal (CAMA) became popular for mass valuation of the real estate in fields like taxation or banking sector.The main weakness of an AVM and a CAMA is the absence of the locational analysis of the real estate; even if the spatial component is a main characteristic in establishing the commercial value of a certain property. Geographical Information Systems may be used in order to improve the accuracy of the Automated Valuation Model (AVM) or Computer-Assisted Mass Appraisal (CAMA) by combining the statistical evaluation methods with the spatial locations on property value.The cadastral maps as part of a geographical information system are essential to correct the mathematical models used in Computer Assisted Mass Appraisal. In this article, we analyze the applicability of geographical information system in property assessment, evaluating if the GIS automated models can be a solution for real estate valuation using a case study from the city of Oradea, Romania.

Aspects Regarding the Modeling of Water Distribution Networks using Geographical Information Systems (GIS) and the Epaet Program

Author(s): Gilda Gavrilaș,Loredana Crengăniș / Language(s): English Issue: 20/2016

Upgrading water distribution systems in towns imposes the study of water distribution networks, starting from a global vision including the current situation, the management of each element of the system as well as their exploitation, development and optimization. The water distribution system consists of a number of interconnected hydraulic elements, each of them characterized by certain relations among the variables that have been chosen to describe their functioning. Currently, the GIS system has the advantage of enabling the collecting and validation of all available information, leading to the possibility of a coherent data set for the elaboration of a hydraulic model. In order to analyse the running of the system, the current practice restricts the analysis model of these elements, so that the parameters could be molded within the existing simulation systems. The paper presents various possibilities to analyse the functioning of a water distribution system.
