Summary

This dataset shows land cover change across North America between 2005 and 2010 at a spatial resolution of 250 meters. It captures transitions between the nineteen Level II land cover classes defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of the United Nations.

Description

This dataset shows land cover change across North America between 2005 and 2010 at a spatial resolution of 250 meters. It captures transitions between the nineteen Level II land cover classes defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of the United Nations.

The dataset was produced as part of the North American Land Change Monitoring System (NALCMS), a trilateral effort between Natural Resources Canada, the United States Geological Survey, and three Mexican organizations: the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía), the National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad), and the National Forestry Commission of Mexico (Comisión Nacional Forestal). The collaboration is facilitated by the Commission for Environmental Cooperation (CEC), an international organization created by the governments of Canada, Mexico, and the United States under the North American Agreement on Environmental Cooperation to promote environmental collaboration between the three countries.

Land Cover Change Values

Each pixel value in this dataset encodes a class transition: the first one or two digits represent the land cover class in 2005, while the last two digits represent the land cover class in 2010.

For example:

105: Class 1 to 5 ("Temperate or sub-polar needleleaf forest" to "Temperate or sub-polar broadleaf deciduous forest")

814: Class 8 to 14 ("Temperate or sub-polar shrubland" to "Wetland")

1716: Class 17 to 16 ("Urban and built-up" to "Barren land")

A dataset on general losses and gains is also available for users interested in landscape changes to forest, shrubland, grassland, wetland, cropland, barren lands, urban areas, water, and snow and ice. Data showing 2015–2020 changes between the twelve Level I land cover classes is also available upon request.

Geographic Coverage

This dataset covers Canada, Alaska, the conterminous United States, and Mexico.

Data Sources and Licensing

Land cover transitions were assessed from the 2005 Land Cover of North America at 250 meters and the 2010 Land Cover of North America at 250 meters, both derived from monthly composites of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery over North America. This dataset is produced by the Commission for Environmental Cooperation (CEC), derived from national land cover maps provided by Natural Resources Canada, the National Commission for the Knowledge and Use of Biodiversity, the National Institute of Statistics and Geography, the National Forestry Commission, and the United States Geological Survey.

Title North American Land Change, 2005-2010 (MODIS, 250m)
Abstract (Description) 
This map demonstrates land cover change between 2005 and 2010 in North America at a spatial resolution of 250 meters.

The dataset shows the 2005-2010 changes between the nineteen Level II land cover classes, which were defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of United Nations.

The land cover change data is part of a series of maps produced by the North American Land Change Monitoring System (NALCMS). NALCMS is a collaborative initiative between Canada, Mexico, and the United States to monitor land cover and its change over time. The NALCMS product displayed in this map represents land cover change based on monthly composites of 2005 and 2010 Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery. The NALCMS is a joint project between Natural Resources Canada/Canada Centre for Remote Sensing (NRCan/CCRS); the United States Geological Survey (USGS); and three Mexican organizations: Insituto Nacional de Estadística y Geografía – INEGI; Comisión Nacional para el Conocimiento y Uso de la Biodiversidad – CONABIO); and Comisión Nacional Forestal – CONAFOR. The project is facilitated by the Commission for Environmental Cooperation (CEC).

Title Cambios de la cobertura del suelo de América del Norte, 2005-2010 (MODIS, 250m)
Abstract (Description) 
Este mapa muestra los cambios en la cobertura del suelo de América del Norte entre 2005 y 2010, con una resolución espacial de 250 metros.

El conjunto de datos presenta los cambios registrados de 2005 a 2010 en 19 clases de cobertura del suelo de nivel II, definidas conforme a la norma del Sistema de Clasificación de la Cobertura de la Tierra (Land Cover Classification System, LCCS), de la Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO).

El mapa de cambios en la cobertura del suelo forma parte de una serie cartográfica elaborada en el marco del Sistema de Monitoreo del Cambio en la Cobertura del Suelo de América del Norte (NALCMS, por sus siglas en inglés), iniciativa conjunta de Canadá, Estados Unidos y México para monitorear la cubierta física de la superficie y sus cambios con el tiempo. El producto del NALCMS mostrado en este mapa representa la cobertura del suelo con base en compuestos mensuales de imágenes con una resolución espacial de 250 m obtenidas en 2005 y 2010 por el sensor MODIS (espectrorradiómetro de formación de imágenes de resolución media, conocido por sus siglas en inglés). El NALCMS es un proyecto conjunto del Centro Canadiense de Teledetección (Canada Centre for Remote Sensing, CCRS), del ministerio de Recursos Naturales de Canadá; el Servicio de Estudios Geológicos de Estados Unidos (US Geological Survey, USGS), y tres organismos mexicanos: el Instituto Nacional de Estadística y Geografía (Inegi), la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Conabio) y la Comisión Nacional Forestal (Conafor), facilitado por la Comisión para la Cooperación Ambiental (CCA).

Title Changements à la couverture terrestre de l’Amérique du Nord, 2005-2010 (MODIS, 250 m)
Abstract (Description) 
Cette carte illustre les changements de la couverture terrestre en Amérique du Nord de 2005 à 2010, avec une résolution spatiale de 250 mètres.

Le jeu de données montre les changements observés de 2005 à 2010 entre les 19 classes de couverture de niveau II définies à l’aide de la norme du Système de classification de l’occupation du sol mise au point par l’Organisation des Nations Unies pour l’alimentation et l’agriculture (FAO).

Ces données sur les changements de la couverture terrestres font partie d’une série de cartes établie à l’aide du Système nord-américain de surveillance des changements dans la couverture terrestre (NALCMS, selon le sigle anglais), un projet concerté du Canada, du Mexique et des États-Unis destiné à surveiller cette couverture et les changements qu’elle subit au fil du temps. Les données ont été élaborées à partir d’images satellites composites recueillies mensuellement, en 2005 et 2010, par un spectroradiomètre imageur à résolution moyenne (MODIS). Coordonné par la Commission de coopération environnementale (CCE), le NALCMS est le fruit d’une collaboration entre le Centre canadien de télédétection (CCT) de Ressources naturelles Canada, l‘United States Geological Survey (USGS, Service géologique des États‑Unis) et trois organisations mexicaines, à savoir l’Instituto Nacional de Estadística y Geografía (Inegi, Institut national de statistiques et de géographie), la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Conabio, Commission nationale sur la connaissance et l’utilisation de la biodiversité) et la Comisión Nacional Forestal (Conafor, Commission nationale des forêts).

Supplemental information 
Information on the change in land cover across North America provided by this dataset is valuable for a range of audiences, including international organizations such as the United Nations Environment Programme, nongovernmental conservation organizations, land managers, and scientific researchers. The continental scale land cover data generated under NALCMS can be used to address issues such as climate change, carbon sequestration, biodiversity loss, and changes in ecosystem structure and function, by helping users to better understand the dynamics and continental-scale patterns of North America’s changing environment.

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 Natural Resources Canada, Instituto Nacional de Estadística y Geografía, the U.S. Geological Survey, or the Commission for Environmental Cooperation in the use of these data.

Lineage statement 
This data set shows areas where the land cover classification changed between 2005 and 2010. The 2005-2010 Land Cover Change of North America at 250 meters dataset was produced as part of the North American Land Change Monitoring System (NALCMS), a trilateral effort between Natural Resources Canada, the United States Geological Survey, and three Mexican organizations including the National Institute of Statistics and Geography (Instituto Nacional de Estadística y Geografía), National Commission for the Knowledge and Use of the Biodiversity (Comisión Nacional Para el Conocimiento y Uso de la Biodiversidad), and the National Forestry Commission of Mexico (Comisión Nacional Forestal). 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.  

This data set was created from the 2005 Land Cover of North America at 250 meters and the 2010 Land Cover of North America at 250 meters.

This Land Cover change map shows class transitions from 2005 to 2010 over Canada, Alaska, the conterminous United States and Mexico. Changes have been assessed from Land Cover maps at 250 meters resolution derived from MODIS Imagery over North America.
