Or, for the short attention span
Open GIS is cool
World Leaders in WebMapping Services 3
Overview
• The vision
• Why standards based?
• How does it work?
• Some examples– MapOrganizer– WebMap Composer
World Leaders in WebMapping Services 4
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
World Leaders in WebMapping Services 5
Tracking a terrorist network
• Parse intelligence reports & news channels
• Locate sightings on a map
• Analyse, create links
• Save & share
World Leaders in WebMapping Services 6
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?
World Leaders in WebMapping Services 8
How does it work?
• The OpenGIS Architecture
• OpenGIS Webmapping Specifications
• www.opengis.org
World Leaders in WebMapping Services 9
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
World Leaders in WebMapping Services 13
Two examples
• MapOrganizer– Client tool for Geospatial Fusion Services
• WebMap Composer– Create and publish your own OpenGIS
online application
World Leaders in WebMapping Services 14
The MapOrganizer
• Scenario: tracking a terrorist network– Parse intelligence reports & news channels– Locate sightings on a map– Analyse, create links
