Canadian Geospatial Data Infrastructure Pilot (CGDI)

The main objective of the CGDI Interoperability Pilot (IP) project was to test the feasibility of using open standards-based technology to improve the management and dissemination of CGDI data. In particular, this project demonstrated that technology from multiple vendors based on the Open Geospatial Consortium’s Web Feature Service (WFS) standard could interoperate to provide access to the most current and authoritative data; thereby maintaining currency, avoiding versioning and minimizing duplication of the data.

A secondary objective was to develop a collaborative technical network with CGDI partners to advance the overall development of the CGDI

Live demonstration of emerging CGDI data access and notification service standards (Francais ici)

GeoConnections hosted a Web-based teleconference on November 30, 2007. The Web conference demonstrated the recent success of the CGDI Interoperability project (CGDI IP) which included participation from provincial and federal participants in cooperation with the Open Geospatial Consortium and GeoConnections.

The live demonstration showed the benefits of access to a CGDI distributed network of federal, provincial and territorial data servers (14 in total) and highlighted:

  1. access to place names, roads and municipal boundary data from a distributed network of federal, provincial & territorial servers (14 in total)
  2. direct updates of data in provincial servers
  3. a demonstration of an emergency response scenario


Emerging standards demonstrated include: Web Feature Service, Geography Markup Language, OWS Context and GeoRSS.

Update: A second demonstration was given for an Australian/New Zealand audience.

Démonstration en direct des nouvelles normes d'accès aux données de l'ICDG et des services de notification

GéoConnexions présentera une téléconférence en ligne le 30 novembre 2007, entre midi et 14 h 30 (HE). Cette conférence en ligne permettra de présenter le récent succès du projet d'interopérabilité de l'ICDG qui incluait la participation des gouvernements fédéral et provinciaux en collaboration avec l'Open Geospatial Consortium ainsi que GéoConnexions.

La démonstration en direct soulignera l'accès à un réseau distribué de serveurs fédéraux, provinciaux et territoriaux de l'ICDG (14 en tout) et reprendra les principaux points suivants:

  1. l'accès aux données concernant les noms géographiques, les routes et les limites municipales à partir d'un réseau distribué de serveurs fédéraux, provinciaux et territoriaux (14 en tout)
  2. les mises à jour immédiates des données dans les serveurs provinciaux
  3. la démonstration d'un scénario d'intervention d'urgence

Les nouvelles normes présentées porteront sur le service de caractéristiques Web, le Geography Markup Language (langage de balisage géographique), le OWS Context et le GeoRSS.
