Résumé(disponible en anglais seulement)
The National Mapping Program (NATMAP) is a major geoscience initiative, conceived in 1988 by the Geological Survey of Canada (GSC), aimed at increasing the level of geoscientific mapping in Canada through multiinstitutional and multidisciplinary projects. The methodology used to accomplish this goal includes multiparameter synthesis of geoscience information, and promotion of digital information management and processing standards for geoscientific maps and compilations. The initial NATMAP projects are the Shield Margin (Manitoba and Saskatchewan) and the Slave (Northwest Territories) each having a duration of 5 years. The Shield Margin Project is designed to generate new perspectives of the Flin Flon-Snow Lake Belt and its sub-Paleozoic continuation. The Slave Project will attempt to provide solutions to a number of issues that are essential to improving the understanding of the metallogeny and tectonic history of the Slave Province.
For each project a digital geoscience database will be created containing information from a variety of sources including written and map reference material, raw and derived products from existing GSC/Provincial databases, digital field geology, and the results of analysis and interpretation. Information in many different data structures including text, point, line, polygonal, and raster, will be incorporated. By implementing a digital geoscience database project, participants are able to benefit from rapid distribution of information, computerized map production and revision, computerized analysis, and manipulation of all types of geoscience data. At the end of the projects the digital database will serve as a data archive.
Development of a system and standards for incorporation of digital field data and existing analog geological information into the database for analysis, comparison with other data sets, and subsequent map production is essential for realization of the benefits of a digital geoscience database.
