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

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


ISO/GML Feature Model


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
