Aleksić, M., Faixová Chalachanová, J.: Web application for sharing data on land consolidation developed in the open-source software environment. Kartografické listy, 2019, 27 (1).

Abstract: Land consolidation is a big project, which focuses mainly on reallocation parcels to remove effects of fragmentation in particular cadastral area. This is a complex and long-term process, in which not only is solved fragmentation of the land, but also ownership of the parcel etc. In such a process, it is necessary to keep the participants of the land consolidation constantly informed about the state of the parcels they own. The aim of this paper is to show the process of creating a web application for providing and visualizing data in the process of land consolidation. Web application was created using the R programming language, designed primarily for statistical calculations, which in fact represents an innovative and non-standard procedure for representing spatial data. In order to visualize and publish only important data for the owners, some of the data was imported from PostgreSQL database to integrated development environment for R, called RStudio. For publishing, the data was used Shiny package, which allows the simple development of an interactive web application directly from R. The web application for distributing data before and after land consolidation, besides other fun-ctions, allow users to switch between multiple layers, determine the parcel size either through the use of a tool for it or as a result of a simple query.
