  6. 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)

  7. 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

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

  9. 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’)
