The BC Butterfly Atlas uses the same grid of 10 km x 10 km atlas squares as are being used by the BC Breeding Bird Atlas. The grid square boundaries follow the Universal Transverse Mercator (UTM) coordinate system grid for BC.
Atlas Region Maps
Maps (in JPG format) showing the boundaries and atlas square ID codes of the atlas squares in each atlas region can be downloaded here (use top drop-down menu). Once downloaded, click on the map to zoom in and out on individual squares.
Topographic Maps of Atlas Squares
Maps (in PDF format) of individual atlas squares can be selected and downloaded here. Atlas square ID codes (available from the Atlas region maps) are needed to select and download these maps. Enter the ID code of the desired atlas square map into bottom box.
You will need to have Adobe Acrobat installed on your computer to view and print these PDF maps. The maps have been created to print best on a legal size sheet (8.5″ x 14″) with a landscape orientation.
Interactive Atlas Square Map
A zoomable interactive map of the atlas squares covering the whole province can be found on the BC Breeding Bird Atlas website here. Zoom to your area of interest using the menu on the left-hand side of the map. Use the Layers menu on the right-hand side of the map to add layers showing the atlas squares, blocks, and regions.
Spatial Data Files of Atlas Squares, Blocks, and Regions
Both Google Earth (.kml) files and ESRI shapefiles (.shp) of the atlas squares, blocks, and regions are also available for download:
You must have Google Earth installed on your computer to view the .kml files. Once the files are downloaded and unzipped, click on the individual .kml files to load them into Google Earth. Use of the ESRI shapefiles requires access to a suitable GIS software package such as ArcView (3.x) or ArcGIS (8.x, 9.x, 10.x).
