The aim of the present work is to show and compare the process of transforming the map of the former Austrian cadastre from the analogue format to the numerical version, in connection with its still valid application in geodetic-legal, urban design, and planning processes. These include, inter alia, litigation and court cases regarding the extent of ownership of real estate, work related to real estate management (divisions and demarcations), use of maps of former cadastral systems in the process of land consolidation, or modernization of land and building registers and creation of a digital cadastral map, as well as any research studies pertaining to the analysis of spatial changes in the natural environment. Within the defined scope of research, the following steps were taken: calculation of corner coordinates of the sectional frame, transformation of the obtained coordinates from the KUL system into the “2000” system, followed by calibration and raster vectorization. The calibration process was performed using three different computer software applications, which are used on a daily basis by surveying companies throughout Poland. Serving as the material for research, a cadastral map of the village of Strzelce Wielkie in the Szczurowa municipality was adopted, that had been acquired from the State Archives in Kraków.
