Analiza zjawiska autokorelacji przestrzennej cen transakcyjnych na rynku nieruchomości lokalowych

Author(s): Radosław Cellmer / Language(s): Polish Issue: 1/2012

One of the most important factors influencing price and its effect on the value of real estate is location, which can be considered on both global and local scales. The result is that prices in a given location should be similar and they should show spatial auto-correlation. This paper deals with the essence of spatial autocorrelation and introduces a methodology of measuring spatial dependences. The results of the research concern housing prices in the vicinity of Olsztyn. For research purposes, global and local Morans and Getis-Ord indexes were used along with an analysis of semi-variograms. In this way, both the spatial autocorrelation and spatial differentiation of dependencies between housing prices were determined.

SINERGETINIS RIMANTO KRUPICKO GEOGRAFIJOS PASAULĖVAIZDIS: TARP RACIONALAUS IR IRACIONALAUS

Author(s): Zigmas Kairaitis,Aušra Birgelytė / Language(s): Lithuanian Issue: -/2014

The article analyses the geographic world-view of Lithuanian geographer, traveller, Associate Professor Rimantas Krupickas (1945–2009). The scientific theories of the second half of the 20th century (general systems theories, theories of synergetics, chaos and nonlinear dynamics), principles of systematic thinking and the significance of the rational and irrational origin on the scientific cognition are discussed. All of this is related to the influence of the post-modern science on the scientific attitudes of the Professor. The postulates of the systems theory and systematic thinking that mostly conditioned the Professor’s attitude towards the geography are discussed in more detail. It is reflected in one of his main works – the monograph Systems Theory and Geography (2010). It is accentuated that the Professor associated systems theory and systematic thinking with the perspective of geography as the science.

The Implications of Topography in the Projects of Industrial Infrastructure

Author(s): Ioan Ienciu,Robert Draşovean / Language(s): English Issue: 26/2019

The industrial objectives are the place of the activity necessary for the production of industrial goods intended for the consumption of the population. Due to the technological progress marked by the evolution of techniques and technology, the production and assembly lines of the industrial product have become increasingly complex including automation components such as conveyor belts, machine tools, manipulating robots, cranes, tunnels and other like these. These components, being connected to each other, require the need for special surveying to be placed in the field.In this context, the topographer engineer is present at every stage of the "life" of an industrial hall, starting with the plot, plotting the axes, positioning the posts in the construction phase, marking it in the cadastral registers, drawing machine tools and auxiliary equipment in its endowment phase, the behavior and deformation of the construction during its exploitation and the deletion of the construction during its demolition.

Author(s): Eva Koncsag,Petru Loloiu / Language(s): English Issue: 26/2019

Under the National Cadastre and Land Register Programme launched by the National Agency for Cadastre and Land Registration (ANCPI) in Romania, the systematic registration works initiated by the local territorial units (LAUs) are financed according to the law on cadastre and land registration no. 7/1996 republished with subsequent modifications [1]. Their object are the cadastral sectors within LAUs that include real estate properties outside the built-up areas or, in the absence of land outside built-up areas, at the level of cadastral sectors inside the built-up areas, irrespective of their owner or holder. The aim of the Programme is to accelerate the development and implementation of cadastre in Romania, to register properties into the integrated cadastre and land registry system, free of charge. It is also aimed at developing and implementing the cadastral map of real estate properties and at opening the land registers at the level of all territorial units in order to support the implementation of the new payment schemes in agriculture. Thus, the present paper presents the implementation of systematic cadastre in Sibiu, Gura Riului commune, in sector no. 29.

Using GIS for the Calculation of Equalization Volumes of Horizontal Platforms

Author(s): Luciana Oprea,Tudor Borşan,Robert Draşovean / Language(s): English Issue: 26/2019

The lands designated for construction are generally irregular facts that are leading to various constructional malfunctions. These irregularities of the land require leveling works in the form of horizontal or inclined platforms where appropriate. In order to solve these problems, it is necessary to calculate the volumes of materials to be used or dislocated in order to carry out the designed works.Thus, the present paper aims at the efficiency of digital modeling in order to equalize a horizontal platform. By digitally modeling the data taken from topographical measurements and making use of the architectural plan, the areas most affected by the altimetry will be easily identified, these areas being subjected to correction works in order to bring them to the level of the design.

Intervention Measures on Buildings Affecting by Humidity

Author(s): Dorin Popa,Luciana Oprea,Ciprian Ţibea,Adela Elena Radu / Language(s): English Issue: 26/2019

At present, a number of historical buildings and monuments are affected by a common phenomenon, namely the capillary rise of water through foundations and walls, resulting in the appearance of dampness. At first glance this phenomenon does not receive the proper attention, which is why in a very short time it makes its presence felt by: efflorescence, molds, the appearance of molds and lichens, the fall of plasters, degradation of bricks, horizontal and vertical cracks, sediments. In addition to the fact that this "cancer" of construction called dirt creates an unsightly appearance, unpleasant, pungent odor can lead to the reduction of building stability and hence the thermal transfer is higher by a wet wall compared to a dry one. Thus, this paper aims at presenting the ways of intervention on a building affected by humidity, by making the study of a building located in Sibiu, consisting of a dwelling house, fencing and land.

The Role of Models in Cadastre

Author(s): Ion Botnarenco,Efim Zubco / Language(s): English Issue: 25/2018

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(s): Floarea-Maria Brebu,Alina Corina Bălă / Language(s): English Issue: 25/2018

Based on the theories of Ptolemy emerge so far and Romania various systems cartographic projections: Stereographic 1930, Stereographic 1970 or 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 of using one or the other.Based on the above-mentioned criterion, the scientific paper aims 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.

Actual Approaches on the Water Utilities Data Models

Author(s): Ana Cornelia Badea,Gheorghe Badea / Language(s): English Issue: 24/2018

In November 2017 the Technical Normatives about producing spatial datasets on public utility networks was approved and published by National Agency of Cadastre and Land Registration. Romania has undertaken the implementation of INSPIRE, so identifying the best ways to put it into practice is an essential step in the application of these rules. Currently there are developed models for water and sewerage networks, designed both using company software and open source software solutions. From cadastral and urban management viewpoint, it is very important that the utility networks to be correctly and complexly modeled, justifying the importance of presented analysis. Its importance is due to the fact that utilities networks are fundamental parts of the smart city concept, being integrated with the cadastral information. The implementation of concepts that lead to 3D modeling of standards-compliant utilities networks, while also offering open-source access, is a top priority, including at international level. The present article aims to analyze these models by highlighting their current status and defining important aspects.

Author(s): Floarea-Maria Brebu,Alina Corina Bălă,Tudor Borşan / Language(s): English Issue: 24/2018

In the past decade, data acquisition possibilities multidimensional were quickly improved method for determining the spatial position, models multi-dimensional objects using panoramic images. The visualization model thus created plays an important role in various applications such as urban planning, documenting cultural heritage and animation, and documenting historic buildings and sites, etc. Multi-dimensional 2D, 3D or 4D models are also a new way of presenting spatial data as a final product for measuring objects in the field. Capturing images and viewing them will soon be a core technology within the geospatial domain. It will not be based on field measurements where individual points are measured and time spent on the ground is lower, increased flexibility but the new results will provide new opportunities and a strong competitive advantage.This article describes an approach using panoramic images captured by V10 Trimble technology to enhance the details and realism of the geospatial data set in order to build 2D, 3D or 4D multi-dimensional models and virtual reality applications.

Author(s): Tamás Jancsó,Peter Udvardy,Krisztian Imre Kovacs / Language(s): English Issue: 24/2018

The paper deals with the 3D modelling based on photos. The target object is an interior space of a church. The photos were taken with a DJI Phantom Advanced UAV. Since the GPS receiver is not available inside buildings, the photos were taken in manual mode. In order to organize the shooting positons into vertical strips, the photos were taken from three different stations from different vertical positions. The 3D model was built with AgiSoft PhotoScan software. The camera calibration was carried out prior the processing to ensure a higher accuracy. The scale of the model was setup by reference distances and points. The experiments showed us, that the created model is suitable not only for demonstration and artistic purposes, but for engineering measurements as well.

Author(s): Cornel Păunescu,Florin Nache,Vlad Păunescu,Roxana Nache / Language(s): English Issue: 24/2018

The systematic cadastral works are carried out on the whole ATU (Administrativ Territorial Unit) or on cadastral sectors. In this paper we refer to the implementation of the systematic cadastre on the whole ATU. The basis of the work is the Order of the General Director of the National Agency for Cadastre and Real Estate Publicity (ANCPI) no. 533/2016, published in the Official Gazette Part I no. 362/11 May 2016. There are also provisions on this type of work in Law no. 7/1996 (Law of the Cadastre and Real Estate Publicity) and in Order no. 700/2014 of GD of ANCPI. Within OGD 533/2016 we consider that many of the provisions regarding the verification and reception of works leave room for interpretation. It is not clear what error or mistake is, repeatedly mentioned as reasons for rejection of the work. We consider that it is strictly necessary to define them clearly and without interpretation.

Registration of Land Rights Depending on the Evolution of Land Legislation

Author(s): Ion Botnarenco,Efim Zubco / Language(s): English Issue: 23/2017

Over a relatively short period of time, the legislative framework of the Republic of Moldova has undergone a fundamental evolution: from state monopolism to private ownership of the land fund. Land legislation, which is dominated by private ownership, in the period 1992-2017, which we will consider as the current period, has also undergone, under the influence of economic relations and implementation of economic policies, a structural evolution by forming new types of rights with social, economic and ecological content. The main issue that has become current in the context of these developments is related to the recognition and protection of the newly formed rights. An important role in solving this crucial problem is given to the registration of the newly formed rights. The analysis of the created situation confirms its objective need and also the interaction between the land registration process (real estate as a whole) and the law development process. The lack of interaction and the denial of objectivity of this interaction represent the beginning of a social economic crisis. Current status of this situation is being studied in the Republic of Moldova.
