Abstract:
This data set consists of 12 separate images that are clear-sky composites of
generalized land-surface cover in North America during 2006. There is one image
for each month of 2006; together these images capture seasonal land-cover changes.
The Canada Centre for Remote Sensing, Earth Sciences Sector of Natural Resources
Canada produced these images fromdata obtained with the Moderate Resolution
Imaging Spectroradiometer (MODIS) instrument aboard the Terra satellite. This
satellite, part of NASA’s Earth Observing System, passes over the entire Earth's
surface every 1 to 2 days. Each of the images in this series is a composite,
assembled from ten days worth of satellite observations, to create a mostly cloud-
free view. The MODIS top-of-atmosphere reflectance data was resampled to 2.5
kilometers per pixel from the original spatial resolution of 250 or 500 meters per
pixel, and was converted to TIF format to provide easily accessible images showing
generalized land cover for North America. To highlight differences in land cover,
a false-color composite is used: ice and snow appear in pink, dense vegetation in
orange, sparser vegetation in green, and water in dark blue.
Purpose:
The North American Atlas data are intended for geographic display and analysis at
the national and continental level. These data should be displayed and analyzed at
scales appropriate for 1:10,000,000-scale data. No responsibility is assumed by
the Commission for Environmental Cooperation in the use of these data.
Supplemental_Information:
This data set consists of twelve monthly images and associated world files, in a
single zip file. The files use a consistent naming convention: na##.tif for the
TIF images, and na##.tifw for the world files, where ## is the numeric indicator
for the month. For example, na09.tif is the image for September, 2006.

America, at 250meter spatial resolution and monthly temporal resolution,are

Top-of-atmosphere reflectance data provides information about the energy reflected
from the surface of the Earth, as measured at the satellite location at the top of
the atmosphere. Corrections to adjust for scattering and other atmospheric effects
have not been applied to these data.

The Commission for Environmental Cooperation (CEC) is an internationalorganization
created by Canada, Mexico, and the United States of America under the North
American Agreement on Environmental Cooperation (NAAEC). The CEC 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 theenvironmental provisions of the North American
Free Trade Agreement (NAFTA). Further information on the CEC is available from

Data_Quality_Information:
Logical_Consistency_Report:
No tests for logical consistency have been performed on this data set.
Completeness_Report:
Data completeness reflects the content of the original MODIS data. These images have
been resampled from the original data and therefore represent a generalized picture
of seasonal land cover change in North America.
