World Leaders in WebMapping Services 2

Or, for the short attention span

Open GIS is cool


Overview

• The vision

• Why standards based?

• How does it work?

• Some examples– MapOrganizer– WebMap Composer


The vision:

• To share, integrate and publish spatial and non-spatial information over the Internet– Vendor and format independent– Utilising web-services– Creating rich information

• Enabling, rather than creating, the links


Tracking a terrorist network

• Parse intelligence reports & news channels

• Locate sightings on a map

• Analyse, create links

• Save & share


Create your own view on the world

• Configure an online application viewer

• Link in Map Services from all over the world

• Customise your own view

• Publish the result as a URL

• Link from your own website

• All in 30 minutes


• Value of the network– Serve once, use many– Use third party Web Services– Value grows exponentially with number of nodes

• Avoid the need to centralise:– Security – Quality Control – Custodianship– Maintenance

Why open standards?


How does it work?

• The OpenGIS Architecture

• OpenGIS Webmapping Specifications

• www.opengis.org

http://www.opengis.org/




The OpenGIS Architecture

• From systems to services• ACORN Services (network addressable

components)– Applications, Catalogs, Operators, Repositories,

Network

• Agreements (“standards”)– Protocols (HTML, XML, GML)– Component interfaces (OGC: WMS, WFS,

Catalogs)


Map Broker

Applications: “WebMap Composer”

Catalog: exploring OpenGIS standard

Operators: broker, renderer, reprojection

Network

OpenGIS services architecture

Data Repositories: WFS, WMS


Two examples

• MapOrganizer– Client tool for Geospatial Fusion Services

• WebMap Composer– Create and publish your own OpenGIS

online application


The MapOrganizer

• Scenario: tracking a terrorist network– Parse intelligence reports & news channels– Locate sightings on a map– Analyse, create links


Task• General assignment

is to review activities of potential concern– Protests– Police/civilian

clashes – Assassinations– Bombings– Rallies

• Display relevant maps from various sources– Web Map Servers (WMS); NIMA/NASA/ESRI, USA

• Integrated storage of spatial and non-spatial objects– Location Organiser Folder (LOF); SCO, Sydney

• Share the results– LOF manager; Ionic, Belgium


WebMap Composer

• “Wizard” approach to Publishing Templates and Views as Web applications

• Create your own view of the world• Using any OGC compliant Web Services• Publish the result as a URL• Link from your own website• All in 30 minutes


Features

• Support for OGC Web Map Servers, Feature Servers, Catalogs

• Web interface to configure views

• Publish/load configurations as XML documents - re-usable in other applications

“PlanConnect”: What planning instruments

pertain to this area? • State Planning maps

(DUAP-ESRI)• Local Council Maps

(Served locally)• Online Documents• Spatial Metadata

registration


Conclusion• Interoperable services are the way to go

– “Serve once, use many”– Save $$$$$ by eliminating duplication of data and

services

• OpenGIS standards available and emerging• Applications are happening• SCO leading in standards development and

providing solutions

“Enabling the links”
