2. Objectives Information on selected Canadian and International geomatics Discovery, Visualisation (Evaluation) and Access initiatives. Importance of distributed discovery and services. Increase linkages between the bibliographic and geomatics communities. Abstract: The library and archival community commonly use and develop cataloguing schemas to store and retrieve analogue and digital publications. A similar system is used in map libraries. The current challenge is how to optimise the retrieval, evaluation and access of geomatics data. Geomatics or geographical data commonly require search parameters in addition to the standard subject, author and date. Additional geospatial parameters include geographic extent and time range. Similarly, special software and knowledge are required to visually assess and access these data sets. Natural Resources of Canada, a Government of Canada Federal Department, produces a large volume of digital geographic data in conjunction with other Federal Departments, levels of Government and International sources. The geomatics concepts of Discover, Visualise and Access are presented in an operational theatre, and research and development context. International or adopted standards and associated current technology are discussed within this framework.

3. Agenda 1. Background 2. Discover geomatics data via CEONet - Re-Useable Components 3. Distributed visualisation - OGC 4. Access - GeoGratis / USGS 5. Chaining services 6. Build further linkages between the bibliographic and geomatics communities

4. 1. Background Spatial data infrastructure programs and their respective national and international initiatives are based on distributed architecture and open standards. Metadata based discovery, web based visualisation and access are well documented and should be referenced when defining requirements and system architecture.

5. 1. Background The library community has developed over many years cataloguing specifications and protocols. Emphasis on geographic content is not of primary importance and spatial extent is typically based on points or place name. The volume of digital geographic data is incomprehensible (1024) from satellite imagery, airphotos, maps and data warehouses. Software tools exist that enable cross walks between these communities.
