The North American Atlas - Hydrography data set shows the coastline,
linear hydrographic features, and area hydrographic features in North
America. This data has been revised and re-released in 2006.
This data set was produced using digital files supplied by Natural
Resources Canada, Instituto Nacional de Estadística
Geografía e Informática, and the U.S. Geological Survey.
A joint venture involving the National Atlas programs in Canada
(Natural Resources Canada), Mexico (Instituto Nacional de
Estadística Geografía e Informática), and the
United States (U.S. Geological Survey), as well as the North American
Commission for Environmental Co-operation, has led to the release (June
2004) of several new products: an updated paper map of North America,
and its associated geospatial data sets and their metadata.
These data sets are available online from each of the partner
countries for download. This data has been revised and re-released in 2006.
The North American Atlas data are standardized geospatial data sets
at 1:10,000,000 scale. A variety of basic data layers (e.g. roads,
railroads, populated places, political boundaries, hydrography,
bathymetry, sea ice and glaciers) have been integrated so that their
relative positions are correct. This collection of data sets forms
a base with which other North American thematic data may be
integrated. Any data outside of Canada, Mexico, and the United
States of America included in the North American Atlas data sets is
strictly to complete the context of the data.
