Abstract
The main aim of the study was to develop a tool that automatically calculates the basic parameters describing the efficiency of land consolidation work, especially consolidation projects and analysis of the optimal location of parcels. Efficiency is usually determined by basic spatial parameters such as size, number and dispersion of plots. To calculate the spatial dispersion of parcels in a registration unit, the use of a convex envelope (convex hull) is proposed. This is one of the basic functions of a Geographical Information System (GIS). It provides a simple way to estimate the dispersion of land, taking into account its area and its belonging to a particular registration unit. The ModelBuilder application available in ArcGIS software was used to build the efficiency assessment tool. The tool was tested on three consolidation areas – Ilkowice, Rajsko-Niedzieliska-Szczurowa and Łukowa. The best results in terms of optimal distribution of plots were obtained on the Rajsko-Niedzieliska-Szczurowa site. In this case, the average area of plots increased more than threefold. The number of parcels in the entire site and in the registration units has more than threefold decreased. The average dispersion of plots in the units decreased here by almost four times. The other two sites did not score as well, but the analysis of the parameters indicates that there has been an improvement in the distribution of plots compared to the initial state. The average area of plots in Ilkowice increased by about 25% and in Lukowa by about 48%. The number of plots decreased in Ilkowice by about 25% and in Lukowa by about 48%. The average dispersion of plots in the units decreased in Ilkowice by 20% and in Lukowa by about 22%. It should be mentioned here that the Rajsko- -Niedzielska-Szczurowa site consisted exclusively of agricultural plots, so it was definitely easier to achieve such good results. The Ilkowice and Łukowa sites also contained developed plots, which were not consolidated.
