Референцні системи координат колишнього австрійського кадастру та їх використання під час проведення наукових досліджень у карпатському регіоні

Abstract

Cadastral maps of the former Austro-Hungary are valuable source material used in scientific research in different countries. The purpose of this paper is to present the possibility of using the data of the former Austrian cadastral maps for analysis of land uses in the Carpathian region by their transformation. Method. The impulse for such studies was the use of GIS technologies and tools and, accordingly, methods based on the analysis of cadastral maps data after their numerical transformation. To convert data from cadastral maps, information is needed on the local reference coordinate system and projection. In the Carpathian region, covered by the Austrian cadastre, fragments of three such reference systems were used: the Lviv system (the initial point is the High Castle in Lviv), the Vienna (the initial point is the St. Stephen's Cathedral in Vienna) and the Hungarian (the initial point is the Astronomical Observatory in Budapest). Results. The method is proposed and parameters of transformation coordinate reference systems are calculated. Scientific novelty. A methodology is developed that provides the appropriate accuracy of the transformation of the coordinates of the former Austrian reference systems into the modern information space. Practical significance. The results of the conversion and transformation of coordinates can be used to analyze the historical changes in the spatial structure of landscapes and the environment, in the study of rural settlements, the development of landscape gardening, the reconstruction of riverbed changes, and so on.
