Creating an Online Service for Administrative Boundaries: Insights from the 7th EC-GIS Workshop

This presentation outlines the critical steps in developing an online service for administrative boundaries (ABD) showcased at the 7th EC-GIS Workshop in Potsdam. It emphasizes the importance of reliable, accessible, and interoperable systems in the National Spatial Data Infrastructure (NSDI). Key components discussed include data reliability, administrative hierarchy, legal frameworks, data availability, and technical specifications. The role of interoperability at various levels is highlighted, alongside a case study of a Hungarian pilot service, aiming to inspire ambitious goals and efficient resource usage in creating effective ABD services.

  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
