Overview

• CGDI Concepts/Vision
• Development network
• Application overview

CGDI vision
CGDI will enable geospatial applications with
online data and services
e.g. Sustainable Development Transportation
Planning Climate Change Monitoring Disaster
Response Site Assessment Infrastructure
Portal ...
e.g. Features Coverages Projects, Studies,
Activities Events, Situations ...
e.g. Discovery Gazetteer Visualization
Location-based ...
Consumers will be able to access many kinds of
geospatial capabilities
.

Development network

• CGDI development network
• Pre-operational environment for
  interoperability testing of emerging
  Web-addressible network services
• Extend CGDI service interoperability beyond
  discovery
• Field-testing of CGDI architecture
  specificationsimplementations
• Mature services contribute to the operational
  CGDI
• Environment for developing CGDI-enabled
  applications
• Benefit to vendors marketing, showcase
• Benefit to new service/application providers
• infrastructure in action, without full
  operational commitment
• Driven by information community requirements,
  use cases
• Direct tie into GeoConnections infrastructure-buil
  ding programs
• Leverage related initatives OGC testbeds, pilot
  projects WGISS test facility etc.

Current situation - standards

• CGDI recommended services and related
  specifications
• Geodata discovery service (OGC Catalogue
  service, Z39.50 profile)
• Web Map Service (OGC WMS)
• Web Feature Service (OGC WFS)
• Geographic Markup Language (OGC GML)
• ISO content standard for geospatial metadata (ISO
  19115 DIS)

CGDI enabled Application - overview

• Demonstration of CGDI services, geobase and
  thematic data in action
• Driven by science-community fire validation
  scenario
• use of Landsat 7 browse Webmapping service to
  validate potential burn area polygons generated
  by AVHRR processing
• assessment of burn area region based on land
  cover and classification
• Joint development with Canadian Forest Service
• Interoperable with Global Observation of Forest
  Cover / CEOS testbed
