A new approach to calculate the land fragmentation indicators taking into account the adjacent plots

Land fragmentation is a phenomenon which constitutes one of the biggest obstacles to profitable agricultural production. Measurable estimation of this phenomenon is possible by a number of known indicators, based on the surface area of parcels in the given area, their location in space and belonging to individual farms. This method of calculation of the indicators is inaccurate due to the phenomenon of neighbourhood of plots which belong to the same owners. For the purposes of calculating the ratios of actual fragmentation of land, these parcels should be treated as one complex. The article presents a proposal for the adjustment of existing methods of determination of the fragmentation of land indicators, taking into account these phenomena. The object of the research covered area of the voivodeship of Malopolska located in the southern part of Poland. Developed by the authors, method of calculation of land fragmentation indicators, based on complexes of land belonging to the same owners (complexes of plots aggregation), gives very good results in the evaluation of the intensity of the land fragmentation. Obtained in this way, indicator’s land fragmentation represents the real situation on the ground.

The concept of using the water cadastre databases components for the construction of multi-dimensional cadastre in Poland

The article has analytical and conceptual character. It contains a detailed analysis of the scope of cadastral information on waters based on actual data from the regional databases, which are established in four logistically major cities in Poland: Warsaw, Krakow, Wroclaw and Szczecin. The authors examine the contents of water cadastre databases in Poland and possibilities of using them in building the 3D cadastre. The concept of using water cadastre as a subsystem of the 3D cadastre presented in the work was carried out using graphical methods of the object-oriented analysis. The authors present a Real Estate Cadastre (REC) model based on synchronisation of the Land Register databases with the water cadastre databases carried out in District Water Management Boards. Modernisation and thematic expansion of Land Register databases, which act in Poland as cadastre, consistent with the presented REC model is a chance to improve the real estate market in Poland.

Algorithm of land cover spatial data processing for the local flood risk mapping

Floods are a natural phenomenon that has always been and will pose a threat to people’s life and health, their property and the environment. Total elimination of the flood is impossible, but the current state of knowledge enables the use of the available tools in order to reduce the scale of these threats. The aim of the study is to develop a methodology of identification of the areas of hindered flow of water, located in the immediate vicinity of rivers. The proposed methodology is based on a study of the land cover. The developed algorithm of land cover spatial data processing for the local flood risk mapping implements GIS tools. Verification of the developed method was carried out on the example of selected rivers in Poland, only one of which is covered by the plans of flood risk management and causes periodic floodings.

Wykorzystanie zintegrowanych technik geodezyjnych do celów wstępnej oceny ryzyka powodziowego

Streszczenie. W Polsce w ostatnich latach obserwuje sie zmiany klimatyczne skutkujące szeregiem anomalii pogodowych, uwidaczniających sie szczegolnie w okresie letnim, w postaci licznych podtopien i powodzi. Dyrektywa Parlamentu Europejskiego z dnia 23 października 2007 r. w sprawie oceny ryzyka powodziowego i zarządzania nim [2007/60/ WE] ujednolicila dzialania mające na celu zapobieganie i minimalizacje skutkow tych zjawisk. Najwazniejszym z nich jest projekt „Informatyczny System Oslony Kraju przed nadzwyczajnymi zagrozeniami” (ISOK), realizowany pod patronatem GUGiK we wspolpracy z KZGW oraz IMiGW. Glownym celem projektu jest budowa elektronicznej platformy informatycznej jako podstawowego narzedzia zarządzania kryzysowego. Z punktu widzenia tematyki podjetej w niniejszej pracy, istotne jest wyszczegolnienie elementow bazowych powstającej platformy. Nalezą do nich: inwentaryzacja i aktualizacja istniejących baz danych wraz z referencjami oraz opracowanie map ryzyka i zagrozen. Wskazany projekt obejmuje zasiegiem opracowania tereny najbardziej zagrozone, znajdujące sie z rejonie zlewni rzek glownych, z pomieciem mniejszych rzek i potokow. Glownym celem niniejszej publikacji jest zwrocenie uwagi na koniecznośc rozszerzenia baz danych ISOK o informacje z obszarow nieobjetych projektem, a systematycznie zalewanych na skutek lokalnych podtopien. Problem ten rozwazono w aspekcie prawnym, technicznym i ekonomicznym.

Implementation of the AHP Method for Determining the Weights of Factors Decisive for the Location of the Municipal Waste Conversion Plant, on the Example of the City of Krakow

Abstract The paper proposes a methodology for calculating the weights of factors determining the choice of location of municipal waste incineration plant (MWIP). Objective and accurate determination of the weights offers the optimal choice of location. To achieve the planned purpose, the method of the analytical hierarchical process was applied. The study included seven potential locations for the municipal waste incineration plant, located within the area of the city of Krakow. The objective of the analysis, which is the subject of this publication, is determination of weights of factors decisive for the choice of MWIP location. These weights were calculated using the method of the analytical hierarchical process. The choice of the method is dictated by the fact that in the studied case we deal with multivariate analysis, and its components are described both in quantitative and qualitative ways.
