Principles of defining and recording data on structures permanently attached to buildings and their influence on coherence of cadastral data on buildings in Poland

The provisions of the geodetic law contain the term “Structures permanently attached to buildings”. These are elements that make up a set of attributes of buildings. At present, attributes of buildings are very complex, giving rise to discussion in the surveying environment. Many of them are impossible to be unambiguously and immediately defined by the surveyor. The surveyor is obliged to identify structures permanently attached to buildings, to define them, and to enter these structures with all their attributes into appropriate databases. This research paper presents the analysis consisting of certain aspects related to an attempt to define these attributes and to determine the principles of assigning their definitions to construction realities. For this purpose, the legal regulations and case-law concerning the studied attributes were referred to. Then, symbolic representation for the presented structures was analysed, as regards its use on geodetic maps. An important element influencing the introduced changes was identified, which is a sign of the times, i.e. digitization of the geodetic and cartographic documentation database. Finally, the Author proposed what changes should be made with respect to the amount of the information collected on structures permanently attached to buildings, as well as to the methods of their presentation on maps.
