Montreal –The North American Land Change Monitoring System (NALCMS), a trinational initiative coordinated by the Commission for Environmental Cooperation (CEC), today released new mapping data depicting land cover change across North America from 2010 to 2015 at a 30-metre spatial resolution, demonstrating key landscape transitions across our continent.
These maps tell a story of changes in the North American environment. Here are three examples of natural and human phenomena that depict the varying ways in which these data help us better understand landscape changes from a broader perspective:
These maps, created from a composite of images assembled from satellite observations (Landsat), are the result of a collaborative effort that harmonized land cover classification systems from Canada, Mexico and the United States into 19 classes, providing a seamless view of the continent at a consistent scale. Users can download the change data and view class transitions between 2010 and 2015 on a pixel-basis throughout the continent.
This geospatial dataset offers invaluable support to international organizations, nongovernmental conservation organizations, land managers, scientific researchers and others, allowing them a better understanding of the dynamics and continental-scale patterns of North America’s land cover and a tool for conducting both regional and local-level analyses.

North American Land Change Monitoring System
NALCMS is a joint initiative among Natural Resources Canada (NRCan)’s Canada Centre for Mapping and Earth Observation (CCMEO), the United States Geological Survey (USGS), and three Mexican organizations: the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía—INEGI), the National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad—Conabio), and the National Forestry Commission (Comisión Nacional Forestal—Conafor), and supported by the Commission for Environmental Cooperation (CEC). http://www.cec.org/nalcms.
The North American Environmental Atlas
The NALCMS is part of the CEC’s North American Environmental Atlas, bringing together maps, data and interactive map layers to allow for continental and regional perspectives on environmental issues that cross boundaries
