Discover, Visualize, and Access Geomatics Data and Services; Current Concepts and Technology Cameron Wilson Government of Canada, Natural Resources Canada, Canada Centre for Remote Sensing, Ottawa, Ontario, Canada The library and archival community commonly use and develop cataloguing schemas to store and retrieve analog and digital publications. A similar system is used in map libraries. The current challenge is how to optimize 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, Visualize 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.
