  1. View far, think local or How to create an on-line service of administrative boundaries? Katalin Tóth Institute of Geodesy, Cartography and Remote Sensing (FÖMI) Hungary 7th EC-GIS workshop, Potsdam

  2. Why administrative boundaries? Systematisation of data Directs vs. Indirect positioning Core part of the NSDI IST related activities 7th EC-GIS workshop, Potsdam

  3. On-line service of ABD Key requirements • Reliability • Accessibility • Interoperability 7th EC-GIS workshop, Potsdam

  4. Data reliability Find best answers and solutions for the following points: • Official data sources and data owners • Administrative hierarchy of the subject of the service • Legal background • Data availability (content , format, delivery methods) Definition of the method for converting data into information • Rules for generalisation • Technical specifications (input, output) 7th EC-GIS workshop, Potsdam

  5. Interoperability Dimension of interoperability (van Oogen, Salgé) • Data Interoperability • System interoperability • Organisation interoperability 7th EC-GIS workshop, Potsdam

  6. Data model • Object of the service: ATUs, completed by attributes • Spatial schema follows the geometrical and topological description • Metadata about data origin, accuracy and update • Service originates from primary data sources • Distributed databases with unique search facilities 7th EC-GIS workshop, Potsdam

  7. System architecture Architecture of the international ABD service 7th EC-GIS workshop, Potsdam

  8. Browsing unit XML/VML based Axiomap 1.2 7th EC-GIS workshop, Potsdam

  9. Hungarian pilot service Dataflow 7th EC-GIS workshop, Potsdam

  10. Conclusion View far… think local • Set ambitious clearly pronounced objectives: reliability, accessibility, interoperability • Align available resources, find the most efficient way of their usage • Create new products • Rely on others’ experience 7th EC-GIS workshop, Potsdam
