  1. CANRI / AURISA Workshop24 May 2002 New OpenGIS technology and its use in the CANRI framework

  2. Future • OGC Web Services • Web Feature Server (WFS) • Data Framework • Local-e Spatial

  3. OGC Open Web Services • OGC Interoperability Test-beds • Addressed practical and theoretical issues • Web Feature Server • “Sensor Web” Use Case • GML for observations • Catalogue architectures

  4. Web Feature Server • Multiple vendors • Exercised with real clients • SCO’s Web Map Composer supporting full “dialog” in interactive GUI: • List available feature types • Retrieve GML schema (and base schemas) • Create Query • Invoke WFS • Map Results

  5. TD database Data service XML – material/thermodynamic properties Modelling service XML (results) WFS use GIS Data Service (WFS) GML (geometry) Control Application SVG(graphics) Portrayal & Graphics service

  6. OWS Measurements, Sensors GML application schemas Drillholes, Geology objects, Geophysics GML basic Features, Geometry Values, Observations Imports xlink XMML XML MarineXML Navigation Charts Marine Science XML Schema WetXML ? Water Quality GBIF ? Biodiversity re-use components from more general languages

  7. SensorWeb • Goal: collect real-time data from remotely deployed sensors, using web-services technology • 3 specification documents: • Sensor Collection Service • OGC Web Service providing information about, and from, a sensor or network of sensors • SensorML • XML language to describe a sensor instance • Observations and Measurements • GML components to serialise measurement data • Typed values, collections and arrays

  8. ISO/GML Feature Model

  9. Catalogue architectures • Multiple catalogues required to meet use cases identified • Theory done on catalogue and service description information models • Harmonised around industry standard (ebXML Registry Information Model) • Powerful hierarchical classifications • To be exercised

  10. CANRI Data Framework • CANRI Project 2001-2002 • Provide an overall structure for natural resources management datasets • Endorsed by the key NSW natural resource management agencies

  11. Data Framework: Planned Outcomes • Classification system for data served via CANRI • Taxonomy of natural resources terms for use in the CANRI catalogue • Enhanced CANRI homepage and map data selection tool • Thesaurus mapped to global de facto standard (GEMET)

  12. Local-e Geo-Spatial Services • LGSA -Networking The Nation • Phase 1: completed • Phase 2: Online

  13. The Vision • Local-e will provide a service for councils in NSW to create and view interactive maps online. • Created by combining shared spatial data and electronic services. • Maps will provide connection to online services

  14. LGSA Webservices: Expandable Base sites - modular “Building Blocks” approach Geo-spatial SPE Portal Standards E-procurement Phase 4: OSD services Phase 3: Bulk upgrades Phase 2: Individual upgrades Phase 1: Base sites

  15. Use Case 1 – Websford Farmer • Assess the applicability of the latest salinity management developments • Surf to Websford Site • Click ‘Salinity Map’ • Type in address to find parcel • View map of Salinity risk, crop health, cadastral boundaries • Asses risk & take measures

  16. Use Case 2 – Websford Citizen • Book public rugby field • Websford council site  “Sports facilities” • Show public sites on city map, nearest to his home • Click on symbol, link to booking service • Check availability, book, e-payment

  17. Use Case 3 – Websford Web Content Manager • Create Salinity Mapview • Upload Crop health mapdata to LGSA hosting site • Select Map template • Populate mapview with Salinity risk map, crop health, parcels, topographic map. • Publish as URL, and link from website

  18. Use Case 4 – LGSA map manager • Hears about RTA roadmap service • Adds it to available map services list (“catalog”) for councils to use

  19. Functional Requirements • Viewing client • End users/councils: low-bandwidth browser based “Thin Client” • LGSA Maintenance: less restrictions • Standards • Distributed, vendor independent  Open Standards • OpenGIS/ISO standards best suited

  20. Data Requirements • Upload compatible with popular formats • Access to 3rd party data sources • Base data • Topographic Map (1:25000 – 1:50000) • Cadastral Map • Contours (e.g. catchment analysis) • Infrastructure (roads and transport) • Application Specific Data (as available)

  21. Benefits • Independence from software providers • Re-use of existing (data-) resources • Flexibility of upgrading individual components • Enable growth path • Save money and resources
