CANRI / AURISA Workshop24 May 2002 New OpenGIS technology and its use in the CANRI framework
Future • OGC Web Services • Web Feature Server (WFS) • Data Framework • Local-e Spatial
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
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
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
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
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
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
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
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)
Local-e Geo-Spatial Services • LGSA -Networking The Nation • Phase 1: completed • Phase 2: Online
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
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
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
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
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
Use Case 4 – LGSA map manager • Hears about RTA roadmap service • Adds it to available map services list (“catalog”) for councils to use
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
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)
Benefits • Independence from software providers • Re-use of existing (data-) resources • Flexibility of upgrading individual components • Enable growth path • Save money and resources
