1 Cadastre in the context of SDI and INSPIRE Dr. Markus Seifert Bavarian Administration for Surveying and Cadastre Cadastre in the digital age the approach in Germany 3 rd CLGE Conference, Hanover,

2 Outline 1. Introduction, the development of the cadastre 2. Cadastre in a Spatial Data Infrastructure 3. Cadastre in INSPIRE 4. The German approach 5. Conclusions

3 1. The development of the cadastre Cadastre always meets specific requirements 150 years ago as well as in the digital age 1872 today But: The meaning of cadastral parcels did not change over time and will not change in the digital age

4 1. The development of the cadastre Advanced technology for cadastral information in the 19 th century and today

5 1. The development of the cadastre Levels of GI Development SDI Source: ISO/TC 211

6 1. The development of the cadastre

7 1. The development of the cadastre Multipurpose Cadastre Control of EU-sponsoring Property and taxation Oil-Pipeline Airport planing Industrialisation Earthquake Forest cadastre Disaster- Management 80 % of all official decisions are based on spatial data

8 1. The development of the cadastre Multipurpose Cadastre today Multipurpose Cadastre data flow Urban renewal Urban planning Land development Projects of rural development Architects Construction engineer Geographer Grundstücksdatenbank - AGLB - Districts Municipalities counties Construction permit Agriculture and Forestry Land register SOLUM-Star Cadastre ALKIS Real estate management Spatial planning, Environmental protection ATKIS (DLM-DGM-DTK) GRUBIS (ALB-DFK) Finance, banks Charted Surveyors Notary Public Energy supplier, Post, Water management, Military geograph.

9 2. Cadastre in a Spatial Data Infrastructure How can users access cadastral data today? Client knows data provider What Give do me you data have? Here That you is what get I the have, data what (and I can pay) Data provider knows client Data provides decide about the content to be provided Communication by standardised web services

10 2. Cadastre in a Spatial Data Infrastructure and what you get Similar data but......differences concerning actuality, criteria of collection, geometry, presentation and documentation of geodata.

11 2. Cadastre in a Spatial Data Infrastructure The SDI - The overall aim (or the vision) Seamless cross-border data Same data structure, formats, portrayal rules etc.

12 2. Cadastre in a Spatial Data Infrastructure INSPIRE SDI in Europe Infrastructure for Spatial Information in Europe European directive for implementation of a spatial data infrastructure Came 2007 into force Until 2009 transposition in national law Aim: Existent spatial data should be made available by using exisiting GI standards and by defining further rules INSPIRE also develops detailed technical implementing rules and technical guidelines Not just the infrastructure (web service interfaces), but also concrete data content will be provided taking into account the user needs

13 2. Cadastre in a Spatial Data Infrastructure How can users access data in INSPIRE? Metadata Catalogue Internet INSPIRE services Transformation Data Country A INSPIRE services Transformation Regional thematic data INSPIRE services Transformation Regional cadastral data

14 2. Cadastre in a Spatial Data Infrastructure Metadata about cadastral information)

15 2. Cadastre in a Spatial Data Infrastructure Components of a SDI Legal regulations (e.g. INSPIRE), GI standards (OGC, ISO) Web Services for discovery, presentation and download Formal information about the data in order to Be able to find relevant data and to analyse The feasiblity for specific purposes Digital spatial data from the surveying and mapping agencies (as reference) and other thematic data

16 3. Cadastre in INSPIRE INSPIRE Architecture Application and Geoportals Registry Service Discovery Service Internet Horizontal Services View Download Transf. Invoke Service Service Service Service Web services Registers Service Metadata Data Set Metadata Spatial Data Set Data Specifications (Feature Cat, App. Schema.. Metadata Data

17 3. Cadastre in INSPIRE Addressed data content to be harmonized INSPIRE Annex I Annex II Annex III Coordinate reference systems Geographical grid systems Geographical names Administrative units Addresses Cadastral parcels Transport networks Hydrography Protected sites Elevation Land cover Orthoimagery Geology Statistical units Buildings Soil Land use Human health and safety Utility and governmental services Environmental monitoring facilities Production and industrial facilities Agricultural and aquaculture facilities Demography Etc.

18 3. Cadastre in INSPIRE INSPIRE specification for cadastral parcels INSPIRE Directive INSPIRE Technical Architecture Overview COMMISSION REGULATION (EU) No 102/2011 of 4 February 2011 amending Regulation (EU) No 1089/2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services Guidelines for Cadastral Parcels UML Data Model

19 3. Cadastre in INSPIRE Requirements for cadastral parcels To be INSPIRE compliant following issues have to be addressed: Provide metadata elements Implement discovery and view services Transform source data into INSPIRE conformant data sets Use the mandatory elements (ID, geometry, label, cadastral reference) Provide download service (WFS or predefined data sets) Only cadastral parcels are required, no owner information Cadastral processes in the national systems will not change

20 3. Cadastre in INSPIRE INSPIRE Roadmap

21 4. The German approach The digital age- Framework for the implementation of ALKIS GI standards GI specifications AAA implementation started in 2005 SDI Germany INfrastructure for SPatial InfoRmation in Europe INSPIRE

22 4. The German approach Interoperability of reference data ALK Automated Real Estate Map ALB Automated Real Estate Register Quite a lot of redundant information AFIS-ALKIS-ATKIS Application Schema ATKIS Offical Topographic and Cartographic Information System Geodetic Reference Points

23 4. The German approach Unified Modelling Language (UML) Parcels, Location, Geodetic Points Houses Buildings, Facilities and other Facts Land Use Relief, DTM Owner, Property Rights Legal Classification, Administration Areas User Profile Migration Objects The AAA application schema is documented by using a conceptual schema language. Such a language have a well defined graphical notation (such as UML for class diagrams) but also a machine-readable format.

24 4. The German approach Adoption of international GI Standards For a maximum level of interoperability the AAA application schema is consequently based on ISO standards Rules for application schema NAS (XML-Schema) (GML) profile Level 1 Feature Catalogue (HTML, RTF) Feature Catalogue (XML) AAA application schema Feature catalogue Geometry, CRS Metadata Conceptual schema language(uml)

25 4. The German approach Modelling of thematic data within the SDI AAA core schema as basis for any thematic information system AAA thematic schema Cadastre (ALKIS) 3D information Real Esate prices Rural development AdV basic schema (modelling principles, profiles of GI standards ) Town planing National Geodata Base Standardised Data exchance interface (XML) Thematic exchange interfaces (XML)

26 4. The German approach Collection of new data based on cadastre Current activities: Digitalization of Soil Classification Legal obligation Users: Finance authorities Rural development

27 4. The German approach Current activities: Registration of land use information Data Sources Cadastre map, DOP Field units Topography (ATKIS) Scale 1:1 000

28 4. The German approach 3D-Model of Buildings as geographic core data in Germany LoD0 LoD1 LoD2 LoD3 LoD4 finished some states (e.g. Bavaria): finished feasibility studies running to be done by private surveyors others: until 2013

29 4. The German approach New in Germany: 3D buildings (exported to GoogleEarth)

30 4. The German approach SDI provides a lot of thematic data that often need cadastral information to support various use cases such as sustainable development daily sunshine period geothermal temperature in 1000m depth

31 5. Conclusions SDI and INSPIRE will not change the basic function of cadastre; property protection is one important pillar in our society In the digital age cadastral parcels maintain and enhance their role as basic information for a lot of use cases (multi purpose cadastre) SDI and INSPIRE will change the data transfer processes With standardized data formats and services an easy access to cadastral information is possible Information about the data (actuality, resolution etc.) will help the user to analyse the data (check the fitness for purpose) Interoperable cadastral data (cross countries) will be possible with INSPIRE But: still some issues to be solved (pricing, licencing )
