  1. Hans Rudolf Gnägi Switzerland NSDI Switzerland • Organizational and fundamental aspects • Foundation: o Swiss super federalism, 26 Kantons (since 1291, 1848) o RAV , revision of official surveying (1983 – 1993) o Model Driven Architecture (INTERLIS) (1985 – 1991) o Competence Center (1994) o KOGIS coordination group for federal GI * (1.1.2001) • Standards: o SN612010 Data security (SN = Swiss Norm) o SN612020 Datareference model DXF (Drawing eXchange File) o SN612030 INTERLIS 1, SN612031 INTERLIS 2 o SN612040 Addresses of buildings o SN612050 Metadata (profile of ISO19115) o SIA 405, 2013, 2014 Utilities (SIA Swiss Engineers & Architec.) o ISO191xx application (xx = 03,07,09,10,11,15,17,18) o OGC principles for access to distributed data * new: NGN National platform geo-standards (Geo-Normen)

  2. NSDI Switzerland • Organizationaland fundamental aspects • Legal framework: o ZGB (ZivilGesetzBuch), Swiss civil code o BRB (BundesRatsBeschluss) Federal Government Executuve Order on L+T (LandesTopographie) federal office of topography) o VAV (Verordnung amtliche Vermessung), order for the official surveying o TVAV (Technische VAV), technical order for off. Surv. o BRB on KOGIS (coordination group for Gi on fdl. level) - Funding: o official survey, KOGIS: federal; o standards: mixed * * new: NGN National platform geo-standards (Geo-Normen)

  3. NSDI Switzerland • Organizationaland fundamental aspects • Roles and responsibilities: o L+T: maps 1:25’000, 1:50’000, 1:100’000 etc + vector data digitized from maps o V+D (VermessungsDirektion) directorate of official surveying: cadastral data o KOGIS: coordinate geo-data of all federal agencies o SNV/SVVK (Swiss Standards assoc. / Swiss association of surveying engineers): national and internat. standards o SIA: utilities • Intellectual property rights and pricing: heterogeneous, o aim KOGIS: basic data & maps 1:25’000, 1:50’000, 1:100’000 are available for free • Educational aspects: New needs MDA

  4. NSDI: Switzerland • Content • Core data: maps (digital), vectors from maps (buildings,…) cadastral (8 topics: points, land cover, parcels, adm.bd.) • Other data: Geostat, located addresses geo-post, utilities (water, gas, waste water, electricity, telecom) roads (strada DB) • Semantic interoperability: Yes with INTERLIS 1 and ITF * • Data documentation: Yes with object catalogs and INTERLIS 1 * * New with UML(+) and INTERLIS 2 (OO replaces object relational) and XML/GML

  5. NSDI SwitzerlandAV93-layers according federal law (1.1.1993) 8 Information Layers: Control points Land cover Single objects Heights Local names Ownership Pipelines >5bar Administrative subdivisions

  6. NSDI Switzerland • Access to information • General System-neutral (INTERLIS-based) – GIS-based (C-Plan, …) fully public – inter-governamental • Discovery services communal: Zurich (Geo-Shop, sn/ig), St.Moritz (gb/fp) canton: Basel (Geo-Shop, sn/fp), Aargau (gb/fp), Zug (gb/ig) federal: SIK/GIS catalog (DOS/fp) * • Data access and geoprocessing services Geoshop = select,order and get data in different formats by e-commerce methods (still system-neutral!) * New (fall 2002): KOGIS metadata-server profiling ISO19115 (Geo-Shop, sn/fp). SIK = Swiss Informatics Conference

  7. NSDI Switzerland • User expectations and benefit – objectives of the infrastructure • Driving applications o official surveying o cities and cantons on the Internet o utilities o national metadata server of KOGIS o organization of national platform of geo-norms • eGovernment, eEurope o “guichet virtuel” just starts Swiss federal e-government o e-geo = GI part organized by KOGIS (fall 2002) • Exploitation of public information o is actually possible on communal and cantonal level o will be possible on federal level

  8. NSDI Switzerland Highlights • Swiss Federal Geodata Strategy • Signed by the Federal Government and published in July, 2001 (see www.kogis.ch) • One of the main issues: NSDI is of equal importance as traffic, and telecommunication infrastructures for Switzerland! Introduction

  9. NSDI Switzerland Highlights • The ISO approach applied in Switzerland Experienced benefits of the model-driven approach: • Data transfer without information loss • computer-based data checking/validation • free schema extensibility through topic inheritance while remaining compatible • polymorphic read (automated reading of extended models) • presentation (portrayal) services based on conceptual graphic description capabilities • shareable symbology libraries • incremental update ... and more!
