Map Sources

The Atlas maps are composed of several layers of which there are two broad categories: thematic and base layers. Find below a description of each of the map layers. The layer source is included in the metadata.

Thematic Map Layers

Cascadia Subduction Zone

Geodynamics Program, Geological Survey of Canada.

Cascadia Subduction Zone: Tsunami Run-up Potential

Clague, J.J., Yorath, C.J.J., Franklin, R., and Turner, R.J.W. 2006. 'Tsunami hazard zones for southwestern British Columbia.' At risk. Earthquakes and tsunamis on the west coast, Tricouni Press, Vancouver, 200 p..

Tsunami

This map shows a selection of 6 tsunamis and 4 related earthquake events that have impacted Canada and Alaska since 1929. Tsunami events are located in the area of significant impact. Earthquake events are located at their epicentre. Data from: Geological Survey of Canada, United States Geological Survey and British Columbia Ministry of Forests and Range.

Base Map Layers

Atlas of Canada Framework Layers

Base map components are features that provide a geographic context for the thematic data shown on Atlas of Canada maps. These features include rivers, lakes, administrative boundaries, populated places, roads and rail lines. All of the Atlas of Canada base map components are available for immediate free download in five scales and in a number of data exchange formats. The 1:7 500 000 and the 1:1 000 000 scale data are the primary base frameworks used for all Atlas of Canada 6th Edition online maps. You can download Atlas of Canada data from this Web page on GeoGratis.
