| Résumé | (disponible en anglais seulement)
In order to produce a consistent and accurate land cover time series at continental or global scales from satellite observations, an efficient monitoring
approach is required. International collaboration is an effective means to use expertise and combine resources to perform large area mapping and to develop and evaluate methods for land cover monitoring across different ecosystems. In this article,
such an international effort among organizations from Canada, Mexico and the United States aimed at creating a harmonized North American Land Change Monitoring System (NALCMS) is described. The article provides the NALCMS project overview,
objectives, and its current status followed by a presentation of the recently produced North American Land Cover 2005 map at 250m spatial resolution. Details on the satellite data processing methodology and land cover mapping approach used to
produce this map are also discussed. Furthermore, the article evaluates map accuracy based on a comparison with visually interpreted geospatial data and other national reference products. The continental accuracy assessment of the North American
Land Cover yields a 68% agreement with the primary label, and 82.2% with the primary or alternate label used to account for the effect of mixed pixels. |
| Sommaire | (Résumé en langage clair et simple, non publié)
L'article donne un aperçu du projet NALCMS, de ses objectifs et de son état actuel, suivi de la présentation de la base de données North
American Land Cover 2005 récemment produite à une résolution spatiale de 250 m. Des détails sur la méthodologie de traitement des données satellitaires et l'approche de cartographie de la couverture terrestre utilisée pour produire la base de
données sont également abordés. |
