G. Navratil:
"Smart Cities require 3D Information - A Case for a 3D Cadastre";
Keynote Lecture: Symposium GIS Ostrava 2019, Ostrava (invited); 2019-03-20 - 2019-03-22.

The concept of "smart city" aims at making cities more efficient, livable, and socially inclusive. This requires a large number of interconnected systems and services with the necessary infrastructure. These systems and services require data to operate. Traditionally, many of these data sources were two-dimensional, e.g., cadastre, building regulations, city maps, etc. However, in the last decades data sets like 3D city models were created. In addition, with an increasing pressure to use space efficiently and a need to locate space for infrastructure, vertical stacking of infrastructure is the logical next step. Many cities started doing this a century ago with the introduction of underground transportation, but in most cases, the documentation failed to communicate the exact spatial extent of infrastructure. An extension of the cadastral concept could help structure the data and provide a solid foundation for all kinds of smart services like.

The talk explores technical possibilities and limitations, conceptual decisions, legal questions, and visions. Public law restrictions are an essential aspect of a 3D cadastre and augmented reality is one promising technology to visualize 3D information and interact with it. Some visions for future cadastral systems will be presented as well.
