|North American Atlas – Bathymetry
What this map layer shows:
Ocean depths for areas
around North America.
The North American Atlas is a cooperative project involving the Atlas
of Canada, which is part of Natural
Resources Canada; Mexico's National Institute of Statistics and Geography
Nacional de Estadística Geografía e Informática – INEGI);
and the National Atlas of the United
Initial North American Atlas efforts have focused on production of
standardized geospatial data sets at 1:10,000,000 scale, such as boundaries,
water features, and transportation networks. These basic data layers
have been integrated so that their relative positions are correct.
The data are intended to provide a continental view useful for studying
issues that cross political boundaries, such as energy use, the generation
of greenhouse gases, water quality, avian migration, and biodiversity.
Wall maps and additional data layers are planned for the future.
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.
The three national atlas programs work collaboratively to produce the
trilingual data and documentation and to make the data sets available
online. The North American
Commission for Environmental Cooperation (CEC) provides coordination
activities, and is adopting the North American Atlas frameworks (fundamental
map layers, such as streams, roads, and boundaries) as an integral piece
of its information management strategy. The CEC is an international organization
created by Canada, Mexico, and the United States of America under the
North American Agreement on Environmental Cooperation (NAAEC). It was
established to address regional environmental concerns, help prevent
potential trade and environmental conflicts, and to promote the effective
enforcement of environmental law. The Agreement complements the environmental
provisions of the North American Free Trade Agreement (NAFTA).
The North American Atlas – Bathymetry data set shows the depth
in meters for ocean areas covered by the extent of the North American
Atlas project. Isobaths (lines of equal depth) are provided for sea
level (coastline, with depth = 1), 200, 500, and 2500 meters. Polygons
bounded by these isobaths represent depth ranges of 0-200, 200-500,
500-2500, and greater than 2500 meters. This data set was compiled
by the Atlas of Canada, INEGI, and the National Atlas of the United
States®. This data set is available for download only;
it cannot be viewed in the National Atlas Map Maker.
The North American Atlas also includes data sets showing glaciers, hydrography,
political boundaries, populated
places, railroads, roads, and sea
