|North American Land Cover Characteristics – 1
What this map layer shows:
Twenty-five broad classes of land cover, such as urban areas, forests,
and croplands, at a resolution of one kilometer.
Land cover characteristics data describe the nature of the land surface
at a particular location. The staff at the U.S.
Geological Survey (USGS), National
Center for Earth Resources Observation and Science (EROS),
in cooperation with the University
and the European
Commission's Joint Research Centre compile land cover
data as part of the Global
Land Cover Characterization Program (GLCC).
This effort is part of the National
Aeronautics and Space Administration Earth System Science Pathfinder
Program. The land cover information
is drawn from Advanced
Very High Resolution Radiometer (AVHRR) data
and results in a 1-km resolution global land cover characteristics
database that is used for a wide range of environmental research
and modeling applications, including watershed management, environmental
inventories, and land management.
The North American Land Cover Characteristics – 1 Kilometer
Resolution map layer is an image showing the types of land cover
found in North America, excluding Hawaii, the eastern part of
Greenland, southern Mexico, and Central America. There are 25
classes of land cover, including urban and built-up land, cropland
and pasture, shrubland, grassland, deciduous and evergreen forest,
water, wetlands, and tundra. This map layer was compiled by EROS.
The National Atlas also includes a 200 meter resolution image
showing more detailed Conterminous United
States Land Cover,
with classification based on a modified
Anderson classification scheme.
