The aim of the paper was to present the possibility of processing cadastral data in order to obtain material that could serve as a valuable source of information in the analysis of the current state of records. The paper presents a methodology for processing cadastral data, which provides material that can be compared with data from the Land and Buildings Register (EGiB). The research area was the Niedzieliska cadastral precinct, located in the municipality of Szczurowa, in the Brzesko district, in the Małopolskie Voivodeship. Based on processed cadastral data and data contained in the EGiB database, the paper determines the differences in the area for 15 cadastral parcels. A comparison of the two records showed that cadastral data allow for analysis of the current state. The implemented methodology confirmed the usefulness of archived cadastral documentation in the analysis of the current state contained in the Land and Building Register. The analysis of the obtained results showed that the differences in the area of the cadastral state and the area of the cadastral parcels exceeded 10% in none of the cases, and the average difference did not exceed 0.0075 ha. The developed output material can be applied to detect discrepancies and differences between the source data and the current data contained in the EGiB. This makes it possible to identify areas where the causes of discrepancies need to be explained and the necessary corrections need to be made to remove the discrepancies.
