Athens, May 2003 Spatial Data Infrastructure (SDI)

Athens, May 2003 Spatial Data Infrastructure includes all technological, political and institutional measures making sure, that methods, data, technologies, standards, financial and human resources needed for capture and use of geoinformation are available according to business and economical requirements.

Athens, May 2003 Spatial Data Infrastructure Initial situation in Germany: Decision on Use of Geoinformation adopted by German Parliament in 2001 Federal activities IMAGI Cooperation Federal and State authorities Solutions at state level Metadata, Geodata portals, Pilot projects NRW: MICUS- Market studies, GEOBASIS-NRW, GDI-NRW Policy Document of AdV (10/2001) Strategies and action for establishment of an SDI for Germany Decision of the Standing Conference of the Ministers and Senators of the Interior (IMK; 01/2002)

Athens, May 2003 Spatial Data Infrastructure (2) Components Aim: Acquisition, evaluation and use of GI for customers and users in public administrative bodies, for commercial and non-commercial areas, in research and for the citizen Geodata Basis  Reference Data  Thematic Data  Metadata Geoinformation Network Services and Standards

Athens, May 2003 Integration of Topographic and Cadastre Mapping

Athens, May 2003 „...GIS are becoming very useful tools for handling information on the current land use as well as for monitoring changes in land use. Thus such information systems should combine data from different sources, including topographic maps and satellite images.“ UNECE: Social and Economic Benefits of Good Land Administration, September 1998

Athens, May 2003 Paradigm Shift Economicalness  Much of the information redundant in register and map  Multiple acquisition and maintenance of information Customer Requirements  Users expect geoinformation usable in a flexible manner and integrated service delivery Nation-wide Uniformity of Datasets  Increasing importance (also in a European context)  Decision of the German Bundestag on the use of GI  Harmonisation at state borders

Athens, May 2003 Since 1997: Concept of AdV for Modelling of Geoinformation of the Official Surveying and Mapping“ Cornerstones Integrated maintenance of graphic data and descriptive data Constant object view Data maintenance without redundancies User profile according to data protection legislation Focus on customers Economicalness of the concept Integration of Cadastre Map and Register (ALK and ALB) Harmonisation of Cadastre and Topographic Mapping (ALKIS - ATKIS)

Athens, May 2003 Target System Uniform geospatial base datasets for Germany Only one data model for Spatial Reference System  AFIS Real Estate Cadastre  ALKIS Topography  ATKIS 3A - base schema, one 3A - application schema NAS = standard-based data exchange format Co-ordinated data capture, maintenance and supply/delivery Geospatial Base Data Information Management (GIM) Implementation (stage-wise realisation)

Athens, May 2003 Harmonisation of Object Catalogues Only one hierarchical structure for ALKIS, ATKIS and AFIShierarchical structure Identical object view for: Land / current land use Buildings and structural facilities Topography Topographic names Determinings in acc. with public law Administrative units Objects for presentation 89 common objects in ALKIS and ATKIS 21 special ATKIS-objects 44 special ALKIS-objects 6 special AFIS-objects

Athens, May 2003 Public-Private Partnership in Land Administration

Athens, May 2003 Transfer of Government Functions to Private Sector Change of land ownership structures Development of land markets Institutional and economic structures Statutory tasks combined with services for the market Synergetic effects by involvement of the private sector Streamlining of institutional arrangements for land administration Establishment of Business Models

Athens, May 2003 Emerging Markets Technical Cooperation Land Registration Services Real Estate Markets Valuation Private-Public Partnership Chance: Delivery of quality land management services to the public as common goal

Athens, May 2003 Case Study Lower Saxony

Athens, May 2003 Decision of the Lower Saxon Parliament: December 2002 Use of Geoinformation in Lower Saxony –Importance of geoinformation –Thorough strategy for state, regions and municipalities –Development of geoinformation and SDI –Transfer to business –Easier access to geodata

Athens, May 2003 The New Legal Basis: Lower Saxon Law On Official Surveying (NVermG)

Athens, May 2003 Reasons for Revision of the Law Information Efficiency Public Access to Data Monopoly-Sharing Georeference Transparency Deregulation

Base Function Maintenance in spatial information systems Legal Function § 2 GBO § 11 BodSchätzG Guarantee for Requirement for state administration to take over geodetic reference and content of data Necessity to identify real estate and its boundaries Updating and corrections compulsory Athens, May 2003

Athens, May 2003 ALKIS - Concept for Migration NI (1) Measures II Addition of new classes of buildings Addition of new classes of land use Capture of areas of soil valuation Requirements: 1) Determining of the geodata to be maintained in the future  Geobasis-NI 2) Enlargement of the object catalogue OBAK- LiegKat NI 3) Delivery of new software

Athens, May 2003 ALKIS - Concept for Migration NI (2) Measures addition of building objects addition of current land use Data capture according to priorities:  Priority 2: capture not compulsory but desirable according to available capacities  Priority 1: capture compulsory for migration to ALKIS

Athens, May 2003 geoMDK ® Metadata

Athens, May 2003 geoMDK ® Future Development W3C - Standards (XML, …) ISO – oriented data maintenance (ISO 19115) Communication/Data exchange based on OGC-standards (Catalog Service, …)

Athens, May 2003 Cadastre Challenges:  Metadata for cadastre acc. to ISO  Integration of cadastre information into topographic mapping, e.g. generalisation of buildings  Customer needs for spatial planning  INSPIRE principles for European Spatial Data Infrastructure  MODELLING OF CADASTRE ACCORDING TO FUTURE SDI NEEDS!

Athens, May 2003 Cadastre and SDI:  Cadastre data form integral part of national SDI, although dealing with regional issues.  Integration of information deducted from cadastre into topographic mapping requires the same standards (data architecture, exchange formats) for enabling interoperability.  Cadastre needs to be involved into SDI matters from the earliest possible stage on.
