Need for cwc2 –Multi-agency requirement for a generic WMS aware component capable of eliminating the complexity of a web mapping component and WMS support from application developers –Application developers, who may or may not be WMS aware, can easily embed cwc2 into their local application Can concentrate on their domain specific application development (i.e. leave the mapping to cwc2)

cwc2 Functionality –WMS aware configurable component for use by CGDI partners and stakeholders –Supports WMS Web Map Context Documents Stateless Catalog Discovery CGDI Services –Gazetteer –Postal Code –NTS Lookup Integration of non-WMS product footprints –Development of API for interactivity and service –Open source technology

–Output applications GeoBase Toporama GeoConnections Discovery Portal –Service Discovery GeoGratis (TBD) Agriculture Canada (5 applications) Environment Canada (CISE) CWC2 Application Examples

Future Work –API for remote invocation –Investigation of remote integration of cwc2 into various application development environments –Training module and materials –Will become public domain technology (‘chameleon’)
