Abstract
Cadasters are an important element of the national infrastructure. Decision-making processes relating to economic activities and crisis management rely mostly on cadastral data. Those processes require geographic information system (GIS) tools. Cadastral models are developed for analytical purposes. Those geometric and topological models are closely related to 2D and 3D space, and they illustrate the connections between cadastral objects. Cadastral models are developed in space in the form of graphs. The basic models of cadastral structures are described in detail in LADM (ISO 19152). The aim of this study was to develop and present a method for building network models of 2D and 3D cadastral structures with the use of CAD and GIS tools. The models are based on data structures available in the relevant applications. The results were presented in view of the available data from a 2D cadastral map and 3D building data. The generated models are presented in geometric format. They are used in network analyses during crisis management operations, and they support evaluations of spatial structures.
