Semantic and syntactic interoperability issues in the context of SDI
(Wydawnictwa AGH, 2020) Chojka, Agnieszka
Interoperability is one of the core concepts of Spatial Data Infrastructure due to the fact that exchange and access to spatial data is the foremost aim of any SDI. These issues are closely related to the concept of application schema that plays a significant role in interchanging spatial data and information across SDI. It is the basis of a successful data interchange between two systems as it defines the possible content and structure of data, thus it covers both semantic and syntactic interoperability. These matters also appear in a couple of questions concerning SDI including, among others, a model‑driven approach and data specifications. Spatial data exchange through SDI involves UML and GML application schemas that comprise semantic and syntactic interoperability respectively. However, working out accurate and correct application schemas may be a challenge. Moreover, their faultiness or complexity may influence the ability to valid data interchange. The principal subject of this paper is to present the concept of interoperability in SDI, especially semantic and syntactic, as well as to discuss the role of UML and GML application schemas during the interoperable exchange of spatial data over SDI. Considerations were conducted focusing on the European SDI and the National SDI in Poland.
A method for hazard mapping illustrated with an example of Fire Service interventions
(Wydawnictwa AGH, 2020) Kowalczyk, Anna Maria; Bajerowski, Tomasz; Ogrodniczak, Michał
Spatial information systems are already widely used and are commonly applied in crisis management. The aim of the study was to develop a method for mapping hazards as a tool supporting crisis management processes and decision‑making processes for the purposes of security and activities of the Fire Service, and the organisation of the National Rescue and Fire System. As part of the study, formulas determining the scale of danger of each event, and a danger scale factor were developed. Hazard maps were compiled using various methods of cartographic presentation, including interpolation, chorogram, and hotspot. The data used was information from the National Fire Service, from an area accepted as representative. The suggested solution proposes a new method for spatial analysis which takes into account not only the number of events as such, but also the weight of hazards they generate, the specified scale of dangers. The conducted study indicates that the hazard map compiled using this method show more spatial relationships than raw statistical data, which enables a better analysis of the studied phenomenon. The end result of the study is the development of algorithms enabling the compilation of a hazard map which takes into account not only the very fact of the occurrence of a hazard but also its weight.
A researcher's view on the proposal of legal regulations regarding major accident hazard assessment in the land‑use planning process in Poland
(Wydawnictwa AGH, 2020) Markiewicz, Maria Teresa
This paper aims at reviewing the core Polish regulations on land‑use planning (LUP) around hazardous plants and presenting a researcher's view on the proposal of a ministerial ordinance on safety distance determination from the plants creating a major accident hazard (Seveso establishments). Currently there are no legal regulations concerning the method of safety distance determination from Seveso establishments in Poland. The method of generic‑distances recommended in the Polish guidelines from 2007 is not mandatory. The author stands by her opinion expressed for the first time in 2015 that Polish legal regulations on safety distance determination from Seveso establishments formulated as a ministerial ordinance are indisputably needed. If the ordinance is issued, it will contribute to a more complete implementation of the Directive 2012/18/EU and will allow nationwide unification of the method of safety distance determination. The consequence-based approach seems a reasonable option in Polish conditions. This researcher suggests an extension of the draft of the ordinance by introducing a reference tool for the mathematical modelling of accident consequences. It is also worth considering the introduction of legal norms for the description of areas designed in the spatial planning documents for the location of Seveso establishments.
Entering parcel boundaries into the Polish register of land and buildings - an analysis of the current state and proposed changes
(Wydawnictwa AGH, 2020) Maślanka, Józef
The Polish register of land and buildings (EGiB), also known as the real estate cadastre, is of both a technical and declarative nature, which means that the data resulting from special technical, formal and legal procedures should be precisely entered into the EGiB database and then made available to users without distortions or deficiencies. The subject of this research paper is the analysis of formal, legal and technical problems that occur in the process of entering data on the boundaries of cadastral parcels into EGiB. Based on the legal provisions, subject literature, as well as real cases derived from surveying practice, the author performs a descriptive formal and comparative analysis of cur‑rent legal and technical solutions used to enter boundaries of cadastral parcels into the EGiB database. As a result of these analyses, the author has concluded that the existing legal solutions allow neither full and precise entering of parcel boundaries nor providing users with correct data resulting from the performed surveys and legal works. Defects, difficulties and barriers faced when entering boundary data into the register can lead to the distortion of the relevant information, and thus to the decreased reliability of EGiB. The author's proposal is to introduce into the application schema the concept of the boundary segment, together with appropriate attributes defining the structure of the cadastral database. This would allow the elimination of many existing problems and provide EGiB users with reliable and complete information.
Agricultural land protection by spatial planning in Bulgaria
(Wydawnictwa AGH, 2020) Moteva, Milena; Marinova, Bisserka
Agricultural land is a basic resource for the livelihood of the Bulgarian population. However, its management is unstable and is connected with many unresolved or wrongly resolved problems which make it difficult to exercise its underlying function. This is mainly due to fragmented land legislation that has a number of disadvantages: the transformation of agricultural land into urban land is easy, control of land quality is poor, and there is a deficiency of agricultural spatial planning regulations. One of the specific tools for preserving the natural function of agricultural land is spatial planning, subject to the strategic documents of the country. According to a newly elaborated concept on agricultural territory planning, this process is two‑staged: on the municipal and on-farm level. The objectives of the paper are: 1) to analyze the effectiveness of national legislation in regard to preserving the natural function of agricultural land, 2) to defend the necessity of the normative framework completion with precise spatial planning rules for agricultural land, and finally, 3) to draw attention to a new concept on agricultural territory planning by presenting the basic cadastral and specific data for performing spatial GIS analyses and elaborating spatial plans. Data from national statistical institutions were used, and methods of analysis and synthesis were applied. The data needed for GIS analyses and elaboration spatial plans for agricultural territory are listed. The paper asserts that spatial planning is a tool for regulating agricultural land use, for setting territory conditions for preserving and improving land quality, for protecting land tenure rights and for developing successful and high‑income agribusiness.
