Digital regional compilations of the geology of B.C. at 1:250 000scale 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 (http://www.empr.gov.bc.ca/Mining/Geoscience/Pages/default.aspx).  They were also used as the geology base for the MapPlace (http://www.mapplace.ca).

 

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.

 

Release of the recompilation is 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 000scale topographic maps. This differs from the numbering convention used for the National Topographic System maps. NTS sheets contained within this tile are listed below.  Preliminary versions of the tiled data were released in 2003, with updates in 2004.  This new province-wide version, and associated tiled data, supersedes the earlier files.

 

Tile NO8 encompasses NTS 1:250,000 sheets 104C, 104F, 104K, 104L, 104M, 104N, 114I, 114O and 114P.

 

All data sets are in shape file format that should be readily usable by most GIS software. They are presented as either decimal degrees (suffix _ll) or BC Albers (suffix _alb). Tiled data are also available in UTM (suffix _utm) projections. All projections use NAD83 as the datum.  The data sets are intended to be used at 1:250 000 scale and their use at greater scales is not recommended.  

 

NOTE: All GeoFile documents referenced on this page are only available as downloadable documents via this web site. No hardcopy data will be available. A DVD containing all data sets is also available for purchase from Crown Publications. The shape files include .AVL files suitable for symbolization by ArcView 3.x users.  A style sheet (BCDigitalMap.style) for ArcMap 8.x users is also available for download.
