In June 2004, the Atlas of Canada released
a new set of 1:10 million North
American framework data as part of a unique
partnership with the National Atlas programs in the United
States (USGS)
and Mexico (INEGI).
This 'framework data' includes a number of map layers: populated
places, hydrology (lakes and rivers), transportation (road
and rail), administrative boundaries, bathymetry, glaciers
and sea ice. These data layers are available free-of-charge
from "‘mirror" servers
in each of the three countries and can also be visualized
via standard protocols (Open GIS Consortium (OGC) Web Map
Servers).
Since many current issues (for example, energy, water
and biodiversity) are continental in scope, our partnership
vision is to build a North American Atlas online. |
