North American Land Change Monitoring System (NALCMS) Collection

Metadata Updated: August 2, 2018

The North American Land Change Monitoring System (NALCMS) is a trilateral effort between Canada, the United States, and Mexico, and is produced by the Canada Centre for Remote Sensing (CCRS), the U.S. Geological Survey (USGS), the National Institute of Statistics and Geography (Instituto Nacional de Estadistica y Geografia, INEGI), the National Commission for the Knowledge and Use of the Biodiversity (Comisión Nacional Para el Conocimiento y Uso de la Biodiversidad, CONABIO) and the National Forestry Commission (Comisión Nacional Forestal, CONAFOR). The collaboration is facilitated by the Commission for Environmental Cooperation, an international organization created by the Canada, Mexico, and United States governments under the North American Agreement on Environmental Cooperation to promote environmental collaboration between the three countries. The general objective of NALCMS is to devise, through collective effort, a harmonized multi-scale land cover monitoring approach which ensures high accuracy and consistency in monitoring land cover changes at the North American scale and which meets each country’s specific requirements. The initial data set used to generate land cover information over North America was produced by the Canada Centre for Remote Sensing from observations acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS/Terra). All seven land spectral bands were processed from Level 1 granules into top-of-atmosphere reflectance covering North America at a 250-meter spatial and 10-day temporal resolution. In order to generate a seamless and consistent land cover map of North America, national maps were generated for Canada by the CCRS; for Mexico by INEGI, CONABIO, and CONAFOR; and for the United States by the USGS. Each country used specific training data and land cover mapping methodologies to create national data sets, which were combined to create land cover for North America. The three countries worked together to produce a definitive list of land cover classifications for the NALCMS 2005 data set; the same classifications were used for the NALCMS 2010 data set. The NALCMS 2005 – 2010 Change product was created by combining NALCMS 2005 and NALCMS 2010.
