Agenda
Agenda

  • 3:30 Context, Purpose and Outcomes

  • 3:45 Demonstration

  • 4:10 Q&A - Discussion

  • 4:30 End Session


1 context purpose and outcomes
1- Context, Purpose and Outcomes

  • What is WFS?

  • Purpose

  • Audience

  • Dependent Projects

  • Participants

  • Outcomes


What is wfs web feature server
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



Who is planning to use wfs
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


Where can i get one
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)


The canri framework
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)


But canri already has wms web map server
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)


Canri wfs involvement
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


Wfs pilot project participants
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


Purpose of this pilot
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.


Technical requirements
Technical Requirements

  • Link multi source water quality data

  • Heterogeneous

  • Using open standards (WFS)

  • Integrated Internet delivery of reports, maps & downloads


Two components
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

Outcomes
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
