Jarosław Bydłosz obtained PhD at the Faculty of Mining Surveying and Environmental Engineering, AGH University of Science and Technology in Cracow, Poland. He is a faculty member since 2001 and works at the Department of Geomatics as a lecturer and researcher. His scope of interests are Geographic Information Systems, cadastre and standardization. The recent activities concern 3D cadastre and issues concerning ISO 19152 “Land Administration Domain Model”. He is a member of Polish Real Estate Scientific Society and Polish Association for Spatial Information. Since 2010 Jarosław Bydłosz is an active participant of FIG joint commission 3 and 7 Working Group on 3D Cadastres.

Abstract
The 3D and 4D Aspects in INSPIRE and ISO 19152

Co-Author: Piotr Parzych, Assoc. Prof, AGH University of Science and Technology

The Infrastructure for Spatial Information in Europe is based on information covering mostly two dimensions. However, the third and forth dimension are present in some specifications. The third dimension (3D) concerns vertical component, whereas time is usually treated as a fourth dimension (4D). The 3D and 4D aspects are present, inter alia, in “Cadastral Parcels" and “Buildings" data specifications, also as the possibility of specification extension. The Land Administration Domain Model (LADM) was published as ISO 19152 standard on the 1st of December 2012. The Land Administration Domain Model provides a reference model serving two goals. They are providing an extensible basis for the development and refinement of efficient and effective land administration systems, based on a Model Driven Architecture (MDA), and enabling involved parties, both within one country and between different countries, to communicate, based on the shared vocabulary, implied by the model. The Land Administration Domain Model also covers 3D, as well as (4D) aspects. Both INSPIRE data specifications and LADM are prepared applying UML notation, but their purposes are different. INSPIRE has strong focus on environmental users, while the LADM has a multi-purpose character (supporting legal security, taxation, valuation, planning etc.). It is also worth noting that the INSPIRE Directive requires taking into account existing standards (article 7 of the Directive).The purpose of performed researches is examining similarities and differences between INSPIRE data specifications (especially “Cadastral Parcels" and “Buildings") and ISO 19152, as well as discussing the general issue of spatial and temporal aspects of INSPIRE and Land Administration Domain Model.
