Abstract

The paper presents a country profile for the cadastre of the Czech Republic based on the ISO 19152:2012 Land Administration Domain Model (LADM). The proposed profile consists of both legal and spatial components and represents an important driving force with which to develop a 3D cadastre for the Czech Republic, which can guide the Strategy for the Development of the Infrastructure for Spatial Information in the Czech Republic to 2020. This government initiative emphasizes the creation of the National Set of Spatial Objects, which is defined as the source of guaranteed and reference 3D geographic data at the highest possible level of detail covering the entire territory of the Czech Republic. This can also be a potential source of data for the 3D cadastre. The abstract test suite stated in ISO 19152:2012—Annex A (Abstract Test Suite) and the LADM conformance requirements were applied in order to explore the conformity of the Czech country profile with this international standard. To test their conformity, a mapping of elements between the LADM and the tested country profile was conducted. The profile is conformant with the LADM at Level 2 (medium level) and can be further modified, especially when legislation is updated with respect to 3D real estate in the future.

Highlights

The cadastre of real estate (KN) is one of the largest data information systems in the state administration of the Czech Republic
Several objectives have been proposed that drive the creation of a country profile based on the ISO 19152 Land Administration Domain Model (LADM) [1]
In October 2014, the Czech government approved the conception of The Strategy for the Development of the Infrastructure for Spatial Information in the Czech Republic to 2020 (GeoInfoStrategy), which serves as a basis for the National Spatial Data Infrastructure (NSDI)

Summary

Introduction

The cadastre of real estate (KN) is one of the largest data information systems in the state administration of the Czech Republic. Using ISO 19152 is recommended for the further development of the register of territorial identification, addresses and real estate and for the feasibility study of the register of passive infrastructure This indicates that, during the implementation of the GeoInfoStrategy Action Plan, there will be a demand for thorough knowledge and understanding of the LADM concept. The NSSO (which includes 3D buildings) is defined as the source of guaranteed, as well as reference (where possible) 3D geographic data at the highest possible level of detail for selected objects in the real world and covers the entire territory of the Czech Republic It is not explicitly stated within the GeoInfoStrategy that the parcels should be registered in 3D. This paper describes a feasible “show case,” which could be used as a type of guideline for others conducting or planning a similar application
