The MapPlace - BCGS Geoscience Map

MapPlace Home

Details: This map, in BC Albers Projection, has all the datasets and expanded geology layers.  The Legend Window to the left of the map is organized into Layer Groups. Look for the expanded geology, mineral occurrence, ARIS and mineral title layers at the bottom of the legend window. Administrative layers are at the top. Topographic layers, including TRIM, are in the middle of the legend window.  Two sets of Level 1 Mineral Resource Assessment layers are available, a shaded version above the geology layers and a solid version below the geology layers. Level 2 MRA for metallic mineral potential is also available.  Map codes were recently rationalized and new updated sedimentary, volcanic, metamorphic, intrusive and ultramafic geology layers were added. Lithologies are displayed and reported by age and rock type.  Geology is compiled at a 1:250K scale.  Compilation scales may be shown with the legend label; scales in brackets, e.g. (<1:1.2M) or (<300K), are the scales, shown in the lower right part of the map, at which the layer is visible.  This map is also available as UTM Projected Maps.

BCGS Geoscience Map


Map Update Features:


January 18, 2010: Draft BCGeologyMap 2010 with QUEST Area Update in digital format (Shape and Manifold files).  This 2010 draft release represents a pilot project to integrate the QUEST compilation into the 2005 edition of the BC Digital Geology Map (Geoscience Map 2005-3).  The new 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 BCGeologyMap: QUEST Area Update is the interpretive result of previous bedrock geology, new mapping, surficial geology, and geophysical and geochemical results.  The draft of the BCGeologyMap is the starting point to streamline integration of past and future geological mapping results into the provincial database.  A future release will include enhanced metadata, cleanup of line work due to projections issues, the integration process methodology, and update on MapPlace.  

December 18, 2009:  QUEST Project Property File Update added: Geoscience BC Report 2009-17 includes a description of the project, a table of the items added with links to the documents, and KML files for the 17 new and 481 updated MINFILE occurrences.  BCGS GeoFile 2009-10 compliments these components with display and links to reports of the new and updated occurrences on the BCGS Geoscience, Exploration Assistant, QUEST, and QUEST-West maps.  The download ZIP file contains extract tables from MINFILE and MapPlace.  The layers are located in the Mineral Inventory Layers group in the maps.

May 26, 2009: Geoscience Map 2009-1 is a digital, one-sheet map of the geology of British Columbia. It is a summary of Geoscience Map 2005-3 at 1:1 500 000 or 1:2 000 000 scale, with simplified units and legend. It can be used as a digital product and printed as a cartographically correct rendition of the geology of British Columbia. This version of the BCGeologyMap is the one best suited for printing as a single sheet.

The layers are linked to reports with Legal Descriptions and PIN Number.  See Metadata on Survey Parcels, with link to Tantalis GATOR System for more information. Reserve sites are linked to Reserves by Year.

March 20, 2005, Added Alberta Bedrock Geology layer (1:1M scale compilation), located in AGS Geology Layers group.  Courtesy of Alberta Geological Survey.

March 19, 2005, Added one-at-a-time Raster display to the BCGS Geology, Exploration Assistant and Mineral Titles maps. This automatically makes all non-selected raster layers not visible when turning on the visibility of a desired raster layer.

Added auto-minimizing layer groups to the BCGS Geology, Exploration Assistant and Mineral Titles maps. This automatically closes open groups that are not visible, leaving visible groups expanded.

March 17, 2005, Added GSC Surficial Geology layer (1:5M) from Surficial materials of Canada, Fulton, R.J.; Geological Survey of Canada, "A" Series Map 1880A, 1995.  Reproduced with the permission of the Minister of Public Works and Government Services Canada, 2005 and courtesy of Natural Resources Canada, Geological Survey of Canada.

March 1, 2005, added 'Bedrock geology - by age and rock class' and 'Terrains' layers with shaded fill to BCGS Geology Layers 2005 group. Useful with 'DEM image hillshade' turned on underneath.

February 10, 2005, added Mineral Titles Online (MTO) tenure layers. Double-click the tenure to link to a report. Updates will be current to previous day.

January 20, 2005, published new Digital Bedrock Geology layers, with new legends, to the Main Maps. The BCGS Geoscience Map features. a new push-button Geology Legend.  The layers that have been added are:

bullet Quaternary Geology
bullet Faults and Contacts
bullet Geology polygons coloured by age and rock class (sedimentary, intrusive etc.)
bullet Geology polygons hatched by rock type (this hatch pattern is transparent and can be superimposed on raster images)
bullet Geology labels based on the lithostratigraphic map unit.
bullet Volcanic, Metamorphic and Sedimentary Rocks by age layers
bullet Basins
bullet Terranes
bullet Geology Legend reports to screen and Excel. Click the Geology button, at the top of the map, to create a geology legend of the screen view.  The legend displays only what is on screen and includes bounding box coordinates and NTS sheet. The 'Bedrock geology - by age and rock class (solid)' layer must be turned on and zoomed in to at least 1:1,500,000 to view the Geology Legend. Note: When printing the Geology Legend to a colour device (PDF or printer) from Internet Explorer, check on Print background color images in Tools, Internet Options, Advanced, Printing.

The cursor flyout also has information on the map unit represented by each polygon plus it gives the poly-id and previous keycode so that geologic errors or revisions can be brought to our attention for specific polygons.  We are looking for feedback on these new layers and would welcome suggestions for improvements etc.

December 16, 2004, Aquifers in British Columbia from Ministry of Water, Land and Air Protection have been added to the BCGS Geology Map. Two layers display above 1:2 million scale, and below 1:2 million scale.  A label layer appears at 1:100,000 scale.  The aquifers are themed by high, medium and low vulnerability. An Aquifer Report table is available using the MapGuide select tool.  The report also links to the Aquifer Classification Database.  For more information on this data theme, visit Aquifers in British Columbia at
