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

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

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
