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 Map Place (


However, numerous errors and inconsistencies were noted within these data sets. The Digital Geology Map of British Columbia Project was designed to address these problems and, in the process, try to produce a seamless digital map of the Province with consistent geological tagging. Where feasible, updates to the geology have also been incorporated during the editing process. However, some “scratch lines” remain in the data reflecting problems due to unresolved differences in geological designations 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 NM9 encompasses NTS 1:250,000 sheets 92E, 92L, 92M, 102I and 102P.


The datasets released here are a preliminary step towards the final goal.  All linework within the tile is now as seamless as possible, but joins with adjacent tiles have not yet been made.  Final versions will be released late in 2003.  All data sets are in shapefile format that should be readily usable by most GIS software.  They are presented in either decimal degrees or BC Albers projections.  Both use NAD83 as the datum.
