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
- Bathymetry
- This map layer shows the depth in metres of oceans surrounding Canada by means of hypsometric tints, (different colours for each depth range). Bathymetry data were derived from The GEBCO Digital Atlas, published by the British Oceanographic Data Centre on behalf of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and the International Hydrographic Organization (IHO).

- Relief
- This map layer shows relief (land elevation in metres), in Canada relative to mean sea level by means of hypsometric tints, (different colours for each elevation range). Elevation data were derived from the Relief map, published in the 5th edition of The National Atlas of Canada.

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.
