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

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

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 AFIS
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

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 FunctionMaintenance 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

Migration
Athens, May 2003
- Structured names/addresses in ALB
- Consistency of ALK and ALB
- Control Point Database: (Deletion of double numberings and multiple coordinates)
- Check of OBAK-conformity with LKP 540
- Check of area coverage in ALK
- Elimination of local control-point-systems/ Introduction of LS 100 coordinates
Measures I
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

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.
