Title: Employing linear artificial neural networks in property appraisal and valuation — possible applications
DOI: 10.15576/GLL/2017.1.17

Published: May 14, 2017PDF [download]
Transactional price is the result of some kind of free market game, and of independent decisions taken by the parties to the transaction. Prices depend on a number of factors, specific to the local real estate market. The impact of some factors is fixed, while others are dependent on the location of the property. Therefore, research into the determination of rules that would describe the relationship between the market price of the real estate, and its market characteristics, remain valid. The article presents the possibilities of applying linear artificial neural networks to real estate valuation. Using a database, the artificial linear neural network is developing a regression model, which produces the results that oscillate close to the market value of the property. The necessary condition is the creation of a database that is representative of the given real estate market.

Title: Edge effect and its impact upon the accuracy of 2D and 3D modelling using laser scanning
DOI: 10.15576/GLL/2017.1.25

Published: May 14, 2017PDF [download]
The edge effect is a measurement error resulting from the reflection of the laser beam on the adjacent walls, or by its breaking on the edges. Coordinates of points in such cases are determined by averaging the measurements in several areas, resulting in their incorrect positioning in space. Corner points are determined with the same accuracy as the other (flat) elements of the scanned object. This effect is frequently mentioned in publications, which typically state the reasons and mechanisms of the error thus occurred. However, there is a lack of specific examples, showing the impact of the edge effect on the quality and accuracy of geodetic and cartographic reports.
In this paper, the authors present sample case studies of the 2D and 3D representation of the test object. The selected corner elements, as well as the vector elements fitted into a cloud of points, show the discrepancy between the breaking points in the drawing (model), and the curved surface of the point cloud. On the basis of the known geometry of the building, distances were determined between the corner points and their representatives on the cloud. In this way, we were able to determine the accuracy of corner points? presentation by means of the cloud of points, and therefore, we were able to determine the size of the edge effect in specific cases.

Title: The analysis of chosen factors of spatial structure of rural areas in villages of Central Poland
DOI: 10.15576/GLL/2017.1.35

Published: May 14, 2017PDF [download]
The article presents a spatial analysis of rural areas in 14 villages in the Białaczów commune. The study has focused on land tenure and use as well as land fragmentation in private farms. On the basis of a synthetic fragmentation index of registered parcels a detailed research of private land fragmentation in villages of the Białaczów commune was carried out. The index calculated for each area allowed to distinguishing four types of villages. The types differ according to parcels? fragmentation, a factor that may be one of the criteria in establishing which villages require land consolidation and land exchange works in the first place.

Title: GIS-based assessment of the feasibility of solar energy applications, in the case of Łazy village
DOI: 10.15576/GLL/2017.1.51

Published: May 14, 2017PDF [download]
The aim of the study was to evaluate the potential of solar plots in Łazy village, located in the municipality of Jerzmanowice-Przeginia, in terms of suitability for the construction of solar power plants of 4 different sizes: large, medium, small and micro. As a part of the study, the modelling of solar radiation and spatial analyses were performed, using the ArcMap 10.3.1 and QGIS 2.8.1. Wien software. The entire test area was divided into 4 classes, according to the insolation potential. The end result consists of maps showing the land with best prospects for solar investments. We have also presented the evaluation of the possibility for obtaining solar energy via photovoltaic panels located on the roofs. Within the village of Łazy, we have identified 63% of the parcels, of which at least 80% enjoy good or very good solar conditions, that is to say, during the year, the solar radiation for these places exceeds 960 kWh ˇ m?2.

Title: Territorial justice for urban and rural regions? About the responsibility
         and role of the bavarian academy for Rural Areas
DOI: 10.15576/GLL/2017.1.51

Published: May 14, 2017PDF [download]
The article describes the one-sided global discussion on urbanization, conducted without developing sufficient future-oriented comprehensive visions and strategies for rural areas. The concepts discussion concerns mostly agriculture; while there is nearly nothing being said about establishing central places, or nurturing small and medium-sized enterprises (SME) in rural areas. Europe and Germany still believe in the principle of cohesion and the goals of the Territorial Agenda 2020 in endogenously developed rural areas, despite some controversial discussions about the need and outcome of specific and even enhanced strategies and measures in shrinking peripheral regions. It is not primarily a question of economy to support rural areas, but it is first and foremost a question of human rights, dignity and territorial justice. The constitutional demand of equivalent living conditions in Germany is a visible expression and result of territorial justice. Fortunately, this issue of justice is now a hot matter of political discussion in the Bavarian Parliament.
In the second part of the article, the indispensable roles and contributions of civil society and NGOs as independent partners and co-producers of the State are described ? such as the Bavarian Academy.

Title: Proposed model for data security protection of cadastral information in Poland
DOI: 10.15576/GLL/2017.1.81

Published: May 14, 2017PDF [download]
The paper presents a proposal for the data security model to protect the cadastral information recorded in the databases of real estate in Poland. The model was developed for the implementation of multi-purpose cadastral tasks. The problem has been considered from the point of view of the smooth functioning of the real estate market. Reliability of the real estate market is guaranteed by the full, accurate, easily available and current cadastral data. The latter is an important piece of information about the area or land, essential for the implementation of most of the real estate management processes. The publication indicates obligatory and optional sources of cadastral information. The basis for the model of cadastral data security system is the compatibility of the assumptions between the said model and the applicable law. The model contains four types of disclosure status for cadastral data (confidential information, public information, incomplete public information, non-confidential information requiring a license). The status was adjusted to specified groups of users of the multipurpose cadastre. The aforementioned groups are based on the entities, acting within the real estate market in Poland. The security model presented herewith assumes a full transition to computer storage media, including the descriptive information and spatial databases, contained in the multi-purpose cadastre, as well as full interoperability of the data collected therein.

Title: Colour management in the process of objects' digitalization using the RevoScan device
DOI: 10.15576/GLL/2017.1.93

Published: May 14, 2017PDF [download]
This article presents the results of a research project carried out by the Terramap Sp. z o.o. company, which resulted in the development of a measuring device to digitize in 3D, allowing data acquisition and processing. A characteristic feature of the devised system is the automatic acquisition of information about both the geometry (spatial digitization) of the object and the colour information on the object within the RGB colour space (high-resolution digital photographs). The dedicated software, designed for the device makes it possible to plan and control the process of data acquisition, followed by data processing, and the development of the material ready for presentation. Implementation of the research results, by constructing the device and its software on the basis thereof, allowed us to significantly accelerate the digitization work, and thus reduce the unit cost of 3D digitalization.
In order to properly manage colour in the processing of data obtained using the device, we have applied a procedure to calibrate the colour of the material obtained. Studies and tests that we have conducted have shown the validity of the measures designed to control the colour of the resulting product. This publication presents the procedure used for colour management, applied in the process of creating a photorealistic 3D model, as well as the results of our research into automating the process.

Title: The use of Network Analyst tool and 2SFCA method to assess fire service effectiveness
         in a city, as exemplified by Łódź
DOI: 10.15576/GLL/2017.1.147

Published: May 14, 2017PDF [download]
The article presents the results of research aimed at defining the potential effectiveness of fire services in the city space. The spatial scope of the analysis comprised the city of Łódź and a 20-kilometre ring around it, which was introduced in order to avoid an artificial barrier in the form of a city boundary. The study comprised all fire departments located within this area as well as individual elements of its built environment, which may be subjected to or otherwise pertinent to interventions of fire fighters. The use of the ArcMap Network Analyst tool and the 2SFCA method allowed us to specify time accessibility of fire service operations; spatial accessibility of individual elements of the city infrastructure to fire service activities; the load of individual fire stations; and the minimum number of departments necessary to take action within the assumed, defined arrival time for intervention.
