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
![Page 9: Integrating geospatial services with distributed multimedia resources Maurits van der Vlugt Webmapping Team Manager Social Change Online .](https://reader033.fdocuments.in/reader033/viewer/2022051622/56649e8f5503460f94b93efa/html5/thumbnails/9.jpg)

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)
![Page 10: Integrating geospatial services with distributed multimedia resources Maurits van der Vlugt Webmapping Team Manager Social Change Online .](https://reader033.fdocuments.in/reader033/viewer/2022051622/56649e8f5503460f94b93efa/html5/thumbnails/10.jpg)
