3 Urgent EU-wide tasks (sustainable development) require the availability of core cadastral data throughout Europe Cost recovery issues, state budgets and new tasks (Europe, SDI) may require the co-ordination of institutional arrangements for real estate cadastre (updating and maintenance) Challenges of new markets require customer orientation and value-added services based on cadastre Metadata should be compulsory International standards for geodata and exchange formats should be applied to cadastre Access to data needs to be harmonised Slide of presentation from Granada/Spain 2002

4 1. Surveying, Mapping and Cadastre in Germany 2. AAA-Concept of AdV 3. Real Estate Cadastre and ALKIS 4. Data and Service Delivery 5. Conclusions

5 Surveying and Mapping in Germany Real Estate Cadastre Geotopography Uniform Spatial Reference Geographical Information Systems

6 Maintenance of: AdV Customer Centres Coordinating bodies Supra-regional users, focal points Linked to Europe Same fees and measuring standards Customer centres for products of the German official surveying and mapping Satellite Positioning Service of the German State Survey Building coordinates and polygons of the German Real Estate Cadastre Geodata of the German State Survey Lower Saxony North Rhine- Westphalia Federal Office for Geodesy and Cartography

7 AdV Fees And Charges Guidelines Applicable for Simple, useroriented and flexible fees and charges Cost transparency State-overlapping use of geospatial datasets (reference data, topographic data, real estate data) ---- SDI and INSPIRE requirements included Based on equivalence principle Uniform recommendations for fees --- Offline mode (advisory services, data delivery) --- Online mode (search and download services,...) --- Uniform fees for standardised products --- Licensing of data use and follow-up products based on geospatial base data --- States should adopt fees and charges. Easy to understand and accept by citizens Easy to handle for employees

12 Land Register - Inventory Serial number of immovable property Cadastral district, sub-district, parcel identifier Location, area, land use (description) Rights, co-ownership acc. to 3 (3) GBO Sections 1-3 Owner, serial number in inventory Encumbrances, restrictions and limitations (servitudes, hereditary building rights, living rights, limitations to the right of disposal.. Order of standing of rights Rights in rem (mortgages, land charges, annuity land charges) Geospatial Base Data Uniform geodetic reference system - position, height, gravity - Substantial structural facilities without buildings and dwellings Land use and special vegetation Territorial responsibilities Terrain contour lines Land parcels Information on ownership Buildings and dwellings Public restrictions, encumbrances or other features (soil valuation)

16 Spatial Data Infrastructure Geodata + Services + Network + Metadata + Geodata providers + Geodata users = SDI Norms & Standards Agreements on use and access

17 Organisation of GDI-NI and link to GDI-DE

18 Data and Service Delivery Information/On Demand - Official information, Standard presentations Via Information System Real Estate Cadastre (ASL), Information System AFIS Supply with digital datasets - Vector data for further processing and use in thematic information systems (evaluation, change-only updates) ALKIS NAS, NBA-method Geo Services/Value Adding Chains Standardised Web Services (WMS, WFS) - Binding application profiles (GDI-DE, GDI-NI) - Customer-oriented, access for third persons as needed No AAA-migration back NBA V e r f a h r e n XML GML XML GML XML GML NAS

19 Data Delivery We support: various file formats (tif, shape,...) Different grid systems Physical data carriers DVD, hard disk Online-Data delivery FTP-Download, Services (WMS, WFS,...) for internal and external use

20 Database Application server (UMN, XtraServer) Web Services Rules of depiction are defined in map files (UMN-MapServer) and in SLD-(XML-)files for the XtraServer. Web-server The Webserver transmits data to clients such as a web browser. Web Map Service (WMS) Web Feature Service (WFS) Norms & Standards (ISO, OGC, W3C) Get Map Get Feature Info Get Feature Describe Feature Type

21 Cadastre information in gif, jpeg, png formats Cadastre: ALKIS-WMS Scales 1:1000 (optimal), 0 1:2000 (complete data), 1:2000 1:5000 (without parcel information) 3 Layers: ALKIS, soil valuation, restrictions according to public law and other determinings 3 Styles: coloured, grey, yellow (transparent) GetFeatureInfo including owners Colour Grey Yellow (transparent)

22 Standardised Web Services WebMapService (WMS) WMS (future WMS 1.3) Configuration of symbols with StyledLayerDescriptor (SLD)/ Symbology Encoding (SE) WebFeatureService (WFS) WFS 1.1 (future WFS 2.0) For all AAA-object types Geometry: Simple Feature and NAS-conform WebMapServices: BasisDLM-WMS (WebAtlas.de) DLM50-WMS (WebAtlas.de) AFIS-WMS ALKIS-WMS Current stage of implementation WebFeatureServices: BasisDLM-WFS DLM50-WFS AFIS-WFS ALKIS-WFS

27 Conclusions Integrating approach towards geodata is necessary Exploitation of geodata requires standardised data and services for the public and close collaboration with the private sector - PPP. Integrated planning and the implementation of plans need integrated geospatial datasets spatial data infrastructures (SDI). INSPIRE conformity of data is a must! Data delivery according to customers needs There is a clear role for the surveying profession in this field!
