On the Nature and Relationships of 3D Spatial Cadastral Objects
Panos Lolonis
After the incorporation of digital Information Technologies (IT) in the regular operations of mainstream cadastral systems, particularly in the advanced countries, attention has been paid in expanding the capabilities of those systems in other areas of operations and capturing additional aspects of the cadastral domain. An important path of work that has been initiated, particularly at the research level, since the beginning of this century deals with the incorporation of the 3rd spatial dimension of cadastral objects (that is, the vertical dimension) into the IT cadastral systems. Most efforts, so far, have focused primarily on capturing and representing the physical and technical aspects of real 3D entities (e.g. buildings, structures etc.) However, in order for those systems to really incorporate the essence of the spatial dimension of the cadastral objects and use it in covering the everyday cadastral activities, it is important to analyze the real nature of physical and abstract objects involved in the process and determine the various relationships that exist among them in the cadastral context.
