North American Land Change Monitoring System

NALCMS is a joint initiative between Natural Resources Canada/Canada Centre for Remote Sensing (NRCan/CCRS), 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 of Mexico (Comisión Nacional Forestal—Conafor), supported by the Commission for Environmental Cooperation (CEC). Since NALCMS began in 2006, specialists from these government agencies have worked together to devise, through a collective effort, a harmonized multi-scale land cover monitoring framework that can be applied across North America with high accuracy, meeting each country’s specific requirements.

The objective of NALCMS is to devise, through a collective effort, a harmonized multi-scale land cover monitoring framework, which can be applied across North America. A series of both 250m and 30m landcover products have been produced since 2001. The latest product is a 30-meter spatial resolution 2010 landcover for North America. Created from a composite of images assembled from satellite observations (Landsat), this product was created through a tri-national collaborative effort that harmonized land cover classification systems from Canada, Mexico and the United States into 19 land cover classes, providing a uniform view of the continent at a consistent scale. This and other landcover products can be viewed and downloaded from www.cec.org.
