BC Digital geology

The Survey maintains and delivers province-wide digital coverage of British Columbia's bedrock geology. 

BC digital geology

The British Columbia Geological Survey offers province-wide integrated digital coverage of bedrock geology, including all details from compilation of field mapping at scales from 1:50,000 to 1:250,000. The BC bedrock geology continuously integrates new regional compilation.

The BC bedrock geology is standardized with consistent stratigraphic code, age and lithology to enable computations. Customized bedrock geological maps and legend can be explored and data downloaded as KML with spatial and non-spatial queries via MapPlace 2, the Survey’s geospatial web services.

The current version of BC bedrock geology is ‘2018-04-05’. Details on updates are provided in the read me notes below. The BC digital geology is available for download under the British Columbia Open Government Licence. The package in the latest data release contains: digital geology in GeoPackage or Esri shapefile format; QGIS or Esri style file for bedrock unit colours, Truetype font for BCGS stratigraphic age symbols, and an image file to illustrate the recommended colour theme for the bedrock polygons.

Open File 2015-02:     British Columbia Digital Geology

Y. Cui, D. Miller, G. Nixon and J. Nelson

British Columbia Digital Geology is the data source used to create the digital Geological Map of British Columbia.  The latest release is based on a framework data model, which consists of attributed geological contacts and faults as linework, and outcrops or centroids as points attributed with bedrock information. It also contains: tables for geological units and colours; ESRI layer files containing  bedrock colour symbols; and a map of British Columbia illustrating the suggested colour theme for the bedrock polygons.

British Columbia Digital Geology provides province-wide coverage of bedrock geology, consisting of integrated geological maps. The British Columbia Geological Survey releases updates as new data are integrated into the corporate database. Data within the current BC Digital Geology may include information that has not yet been released as GeoFile, OpenFile or Geoscience maps.

The data package includes a lookup table for geological units and colours (RGB); a number of ESRI layer files with the recommended bedrock colour symbols, compatible to various versions of ArcGIS (designated by suffix_a##_# in file names); and a map of British Columbia illustrating the suggested colour theme for bedrock polygons.

Y. Cui, F. Katay, J.L. Nelson, T. Han, P.J. Desjardins, and L. Sinclair

Open File 2013-04 is the data source used to create the digital BC Geological Map, which is provided by the British Columbia Geological Survey to clients in mineral exploration, mining, land-use planning, and other areas.

This release consists of integrated datasets including: geological contacts that delineate bedrock units and structures as linear features associated with descriptions or attributions; and bedrock as polygons formed from the geological contacts and attributed with descriptions of the geological units. It also contains: tables for geological units and colours (RGB); and ESRI layer files containing the bedrock colour symbols, compatible to various versions of ArcGIS (designated by suffix _a##_# in file names); and a map of British Columbia illustrating the suggested colour theme for the bedrock polygons.

BC Digital Geology 2010 with QUEST Update

This data release incorporated the QUEST area map compilation into the 2005 edition of the BC Digital Geology (GeoFile 2005-1). The QUEST digital files are from Geoscience Map 2010-1, Bedrock Geology of the QUEST map area, central British Columbia (also Geoscience BC Report 2010-5, Geological Survey of Canada Open File 6476). The QUEST map compilation is the interpretive result of previous bedrock geology, new mapping, surficial geology, and geophysical and geochemical results.

Geoscience Map 2009-01:     Geological Map of British Columbia

P. Erdmer and Y. Cui

Geoscience Map 2009-1 is a print-ready, one-sheet geological map of British Columbia. It summarizes the bedrock geology at scales of 1:2,000,000 and 1:1,500,000. This map was compiled from geological maps by the British Columbia Geological Survey, Geological Survey of Canada, and university and industry geologists.

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.

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 1:1,000,000 scale topographic maps. This differs from the numbering convention used for the National Topographic System maps. Preliminary versions of the tiled data were released in 2003, with updates in 2004. This new province-wide version, and associated tiled data, supersede the earlier files.

GeoFile 2005-01:     Digital Geology Map of British Columbia - Whole Province

N.W.D. Massey, D.G. MacIntyre, P.J. Desjardins and R.T. Cooney

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.

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 1:1,000 000 scale topographic maps. This differs from the numbering convention used for the National Topographic System maps.   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.

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.

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.
