Geo-mapping Frontiers: Updated information on the regions covered by Operations Baker, Bathurst, Keewatin, Northern Keewatin, Thelon and Wager; Nunavut and Northwest Territories: Landsat

Abstract

The Geo-mapping Frontiers project was initiated to improve geoscience knowledge in the least understood parts of Canada's north. Open File 7434 is part of a series of open files, 7434 to 7448, produced during the Geo-mapping Frontiers project. The series contains legacy geology data and remote predictive mapping information for a large part of eastern mainland Nunavut, collected over 2 years. The derived data products from this work are presented in 15 separate thematic packages to keep the downloads to a manageable size, between 1 and 4 GB. ArcGIS users (version 9.3 and above) can download OF 7434 and any of the georeferenced raster data in the rest of the series. Users not interested in geodatabases will find data in shape files in Open Files 7434 and 7435, or in georeferenced raster data in the rest of the series. This series of publications represents a compilation of available data sets for four regions, and their surrounding areas, that encompass a large part of eastern mainland Nunavut. Several interpretive Remote Predictive Mapping (RPM) layers are included. The data sets include airborne geophysics, LANDSAT 7 imagery, lake sediment analyses, as well as legacy mapping and sample data from the Geological Survey of Canada (GSC) archives. This series is the first of a group of reports for the Geo-mapping Frontiers project, and is intended to provide a basis of knowledge for the entire region.
