This release is the final tile of the digital regional compilation of the Geology of B.C. at 1:250 000 scale. Previous tiles were released as a series of GeoFiles during 2003 and made available as free downloads from the BCGS website (http://www.empr.gov.bc.ca/geoscience/Pages/default.aspx). They are also available as the geological base in the MapPlace.
This present compilation for the Queen Charlotte Islands/Haida Gwaii is adapted from recent studies undertaken by the Geological Survey of Canada that resulted in a compilation map by Haggart (2004). Tile numbering is similar to that used for the Cordilleran GIS Map Library (Journeay and Williams, 1995) which conforms to the International Map of the World standard used for indexing 1:1,000,000-scale topographic maps. This differs from the numbering convention used for the National Topographic System maps.
Tile NN8/9 encompasses NTS 1:250,000 sheets 102O (part), 103B, 103C, 103F, 103G (West half), 103J (West half) and 103K.
As with the previously released tiles, all data sets are in shapefile format that should be readily usable by most GIS software. They are presented in decimal degrees, BC Albers or UTM projections. All use NAD83 as the datum. They are available for download from:
Final versions of the data have been released on CD-ROM January, 2005.
