  1. Web Feature Server (WFS) Pilot Project Project Results and Demonstration Jonathan Doig - NSW Department of Land and Water Conservation Maurits van der Vlugt - Sinclair Knight Merz

  2. Agenda • 3:30 Context, Purpose and Outcomes • 3:45 Demonstration • 4:10 Q&A - Discussion • 4:30 End Session

  3. 1- Context, Purpose and Outcomes • What is WFS? • Purpose • Audience • Dependent Projects • Participants • Outcomes

  4. What is WFS (Web Feature Server) ? • Open GIS Interface Specification • Specification released Sept. 2002 • Enabling Technology for • Direct access to Geographic Features in remote, distributed Datasets • Standard format - vendor independent

  5. Access vector data through SCOTS Software

  6. Who is planning to use WFS? • Australia and NZ jurisdictions (ANZLIC/ASDI Standing Committee) • Endorsed OpenGIS as enabling technology for ASDI • NSW Natural Resource Agencies • CANRI

  7. Where can I get one? • Known scheduled/announced releases • ESRI ArcIMS • MapInfo: MapXtreme/Encounter • Intergraph Geomedia product family • Social Change Online WFS Lite, Webmap Composer • FreeFS (http://geoserver.sourceforge.net/html/index.php) • Full list on OGC website (www.opengis.org)

  8. The CANRI Framework • Vision: “To fully realise the strategic value of natural resource information to support overall Government objectives to achieve sustainable management of NSW natural resources” • Providing • Coordination • Communication • Enabling • Data (publish, find, bind) • Systems (technology, vendor independent) • Information Products • Standards (open)

  9. But CANRI already has WMS (Web MAP Server)! • WMS is standard for ‘rendered images’: • Viewing and minimal query (“scratch & sniff”) • WFS allows access to ‘raw data’: • Geographic objects (points, lines, polygons) • Attribute Data Query (e.g. observations) • filter • download • thematic mapping • graphs and tables • Transactional access (add, edit, delete)

  10. CANRI WFS involvement • Requirement • Reporting on Environmental Indicators • SoE (local, State, Commonwealth, Global) • Catchment Blueprints (NAP, NHT) • Sponsor of OGC’s Open Web Services Testbed (OWS 1.1) • WFS Pilot for Water Quality

  11. WFS Pilot Project - Participants • Agencies • DLWC - Data supply & coordination • EPA - SWMCC Data exchange & reporting • MDBC - Observer • Contractors • Sinclair Knight Merz - Project Management • Navigate - ESRI WFS data serving • Social Change Online - WFS data serving & viewing application

  12. Purpose of this Pilot Demonstrate two critical points: 1. The technicalfeasibility of WFS-based interoperable access to cross-government natural resource data stores using the CANRI framework 2. The feasibility of using this technical capability to present the data to users in a simple, useful and meaningful viewing application.

  13. Technical Requirements • Link multi source water quality data • Heterogeneous • Using open standards (WFS) • Integrated Internet delivery of reports, maps & downloads

  14. Two Components • Data serving • Two different WFS serving platforms (ESRI; SCOL) • Standards Based Commercial Off The Shelf (SCOTS) • Viewing Application - Customisation • Query Multiple Databases (Keysites & IDMS) • Display indicators (map, report) • Download selected data

  15. Architecture Network WFS Pilotapplication server Viewer (Browser) Towns, Rivers, States (GA - WMS) Keysites (ArcIMS - WFS) Catchment Boundaries (DLWC - WMS) IDMS (WFS- Lite)

  16. Outcomes • Server Installations & Application • ESRI server @ Navigate partially OK • ESRI WFS experimental (pre-Beta-release) • Not fully OGC compliant • Does not yet process attribute/spatial queries • SCO server (“WFS lite”) • Application Prototype developed • Demonstration - click for live demo or see snapshots on following slides

  20. Next Steps… CANRI Provisional funding for WFS implementation in Natural Resources Reporting - Water Quality Need to resolve Interoperability issues CANRI Board / NRIMS Systems Working Group to decide

  21. Next Steps… Australian OGC Interoperability Pilot Build ASDI reference implementation Services (WMS, WFS) Catalogs Clients Showcase in real world scenario Demonstration late 2003 /early 2004
