Digital regional compilations of the geology of B.C. at 1:250 000 scale were made by staff of the BC Geological Survey (BCGS) in 1992-1996 in support of the Mineral Potential Project. These were released as Open Files and digital downloads from the BCGS website. They were also used as the geology base for the MapPlace.

 

However, numerous errors and inconsistencies have been noted with these datasets.  The Digital Geology Map of British Columbia Project was designed to address these problems and, in the process, produce a seamless digital map of the Province with consistent geological tagging.  Updates to the geology have also been made where feasible.  However, some "map boundary" problems remain reflecting differences in original sources. 

 

The recompilation has been based on the same tiles as 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 NN10 encompasses NTS 1:250,000 sheets 93A, 93B, 93C, 93F, 93G, 93H, 93I, 93J, 93K, 93N, 93O and 93P.

 

The datasets released here are a preliminary step towards the final goal.  All line work within the tile is now as seamless as possible, but joins with adjacent tiles have not yet been made.  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.
