Currently performance of geodesy is characterized by a computerization and informatization. Even the simplest job cannot be done without even the small-est share of digital methods. Sometimes, however, a surveyor must make use of archival materials, including classical evidential maps. Often it turns out, that it is necessary to process such data to digital form. In the case of paper maps, matrices, and manuscript, it is not difficult. However, it requires, from the con-tractor, the knowledge of potential hazards in case of inability to perform such a procedure. Classical maps, of course, should be scan and then calibrate, i.e. to transform the system in which development is to be made. The aim of the authors, who present the issue in light of the fundamental work of surveying, is to show how difficult it is to truly prepare maps in digital format and to protect surveyingcontractor against too much confidence to the re-sults obtained without confronting them with reality.

The subject of the elaboration is an analysis of cadastral data in the graphic part of the cadaster register of land and buildings (EGiB) in the Strzyżów district. The study area includes five register units (communes): Strzyżów, Frysztak, Niebylec, Czudec, Cherry. In total, this represents a 63 cadastral precincts. The study includes cadastral maps located in the resources of the District Documentation Centre of Geodesy and Cartography in Strzyżów. The study was performed basing on the classification of cartographic materials made available for work (Markowska, 2013) in the form of (analog, digital, numeric maps) and scale, date and technique of realisation.The main objective of this paper is to examine the degree of utilization of cadastral maps in EGiB in the abovementioned area in the surveying works. In addition, the paper evaluates the level of modernization and digitization resource EGiB, in order to verify the objectives of the LPIS project carried out by ARiMR. An additional aspect of the paper is to compare the results with the data for the voivodship of Malopolska, in the context of the same belonging history of these regions to the lands of the former Austrian annexed territory.

The article presents the problem of inconsistencies of the lande borders under flowing waters and the shoreline of the river. It presents data register, containing information on the plots under the waters. These include the following databases: cadastral, topographic and administrative. Measurements of the course of the shoreline of one of the mountainous rivers showed large discrepancies between borders of land under the waters and the shoreline of the river. Changes in time and space of the shoreline of the river were determined on the basis of the long term cyclical location and height measurements. The paper aims to show the need of updating cadastral databases related to the borders of land under the flowing waters due to the change of the course of the rivers shoreline. Do cadastral maps always faithfully reflect the course of the border line of this type of objects? How often should they be updated? Cadastral maps as the primary source of information about the borders of land under the flowing waters (rivers) should be updated, after prior verification of the shoreline of the river (for example, on the basis of an orthophotomap). The study showed clearly, that update the borders of land under ...
