The need for accurate registration of underground objects in the 3D cadastre is becoming increasingly common throughout the world. Research studies conducted in this area mostly focus on objects related to transportation or other public utilities and services. However, in settlements with a long history, apart from new objects, there are also various historical objects underground. Such places are not fully discovered, and sometimes they are not even fully inventoried with surveying methods. The aim of this work therefore is to try to describe the possibility of introducing historical undergrounds to the real estate cadastre created for three dimensions, in case of its creation, and to check ground laser scanning as a method of measuring such objects in order to introduce them to the 3D cadastre. Considerations on the inclusion of underground historical objects into the three-dimensional cadastre database began with conceptual considerations. Their result is the elaboration of UML schemas describing relationships among 3D cadastre objects including underground objects. According to the authors, such underground objects should constitute a completely new class called ‘EGB_BuildingBlockUnderground3D’ and be part of the legal space of the entire building represented by the class ‘EGB_BuildingLegalSpace3D’ (the prefix EGB is an acronym of Polish cadastre name ‘Ewidencja Gruntów i Budynków’; in English, it stands for ‘Land and Building Cadastre’). In order to verify in practice the possibility of introducing historical underground objects into the 3D cadastre database, the inventory of the Underground Tourist Route in Rzeszów (Poland) was used. This route consists of a network of underground passageways and cellars built between the 14th and 18th centuries. The measurement was carried out with the application of the Faro Focus 3D terrestrial laser scanner. The underground inventory showed that at the time the current cadastre of land and buildings in Rzeszów was being founded, the boundaries of the cadastral parcels were established without knowing the location of the underground passageways under the Main Market Square. This resulted in a situation in which the objects located underground became parts of more than one cadastral parcel. If a 3D cadastre is created, such a situation must of course be recorded accordingly. The article proposes solutions for such situations.

When defining the patchwork of plots, based on the literature, it lists the types and subtypes, and given their prevalence in the studied villages. Characterized listed types and subtypes the patchwork of plots the adopted villages crossed by the highway, paying particular attention to the fragmentation of the parcels. Particular attention was paid to the occurrence of the patchwork of the outer of plots for the following reasons: firstlythe presence of plots owners do not reside in the surveyed villages (out-of-village owners) and living in the surveyed villages, but with land in other surveyed villages (local non-resident owners), which is an important issue approximately of plots owners to habitat in the complex work of consolidation and exchange of land; secondlyit allows for adjustment of the boundaries of the village, which destroys the highway without immediate execution merge. This should make such a correction using only the exchange of land; thirdly -crossing the village highway of plots prevents access to out-of-village owners and local non-resident owners when their habitats are located on the opposite side thereof. The study of this problem are designed the patchwork table method to both the external patchwork of plots and internal patchwork of plots. Conducting research in this field mapping method was used to present the occurrence of the external patchwork of plots and the internal patchwork of plots on the cadastral maps.

Abstract:Issues specifi ed in the study concern the evaluation of road networks providing access to cadastral parcels in villages divided by a motorway. The scope of the research involves a spatial analysis of three villages: Rogoźnica, Rudna Mała, and Lipie, all located in the Głogów Małopolski commune, in the county of Rzeszów. Based on data from the descriptive and cartographic part of the Land and Buildings register, a detailed analysis was made of the spatial structure and road network providing direct access to cadastral parcels. The conducted research has revealed that the motorway as a linear investment has not only caused the destruction of agricultural roads in the existing agricultural area but has also destroyed connections between villages that have been shaped for centuries.
