Timely delivery for a country of a size like Mexico can only be achieved in a standardized and cost-effective manner by automatic image classification. This paper describes the operational land cover monitoring system for Mexico. It utilizes national-scale cartographic reference data, all available Landsat satellite imagery, and field inventory data for validation. Seven annual national land cover maps between 1993 and 2008 were produced. The classification scheme defined 9 and 12 classes at two hierarchical levels. Overall accuracies achieved were up to 76%. Tropical and temperate forest was classified with accuracy up to 78% and 82%, respectively. Although specifically designed for the needs of Mexico, the general process is suitable for other participating countries in the REDD+ program to comply with guidelines on standardization and transparency of methods and to assure comparability. However, reporting of change is ill-advised based on the annual land cover products and a combination of annual land cover and change detection algorithms is suggested.<\/jats:p>","DOI":"10.3390\/rs6053923","type":"journal-article","created":{"date-parts":[[2014,4,30]],"date-time":"2014-04-30T13:16:54Z","timestamp":1398863814000},"page":"3923-3943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":76,"title":["MAD-MEX: Automatic Wall-to-Wall Land Cover Monitoring for the Mexican REDD-MRV Program Using All Landsat Data"],"prefix":"10.3390","volume":"6","author":[{"given":"Steffen","family":"Gebhardt","sequence":"first","affiliation":[{"name":"National Commission for the Knowledge and Use of Biodiversity (CONABIO),  Liga Perif\u00e9rico-Insurgentes Sur 4903, Parques del Pedregal, 14010 Tlalpan, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thilo","family":"Wehrmann","sequence":"additional","affiliation":[{"name":"National Commission of Natural Protected Areas (CONANP), Camino al Ajusco 200,  Jardines en la Monta\u00f1a, 14210 Tlalpan, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Ruiz","sequence":"additional","affiliation":[{"name":"National Forestry Commission (CONAFOR), Perif\u00e9rico Poniente 5360, San Juan de Ocot\u00e1n, Zapopan, 45019 Jalisco, Mexico"},{"name":"Representation in Mexico, Food and Agriculture Organization of the United Nations (FAO), Farallon 130, Jardines del Pedregal, 01900 Alvaro Obreg\u00f3n, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro","family":"Maeda","sequence":"additional","affiliation":[{"name":"National Commission for the Knowledge and Use of Biodiversity (CONABIO),  Liga Perif\u00e9rico-Insurgentes Sur 4903, Parques del Pedregal, 14010 Tlalpan, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse","family":"Bishop","sequence":"additional","affiliation":[{"name":"Woods Hole Research Center (WHRC), 149 Woods Hole Road, Falmouth, MA 02540, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Schramm","sequence":"additional","affiliation":[{"name":"Representation in Mexico, Food and Agriculture Organization of the United Nations (FAO), Farallon 130, Jardines del Pedregal, 01900 Alvaro Obreg\u00f3n, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rene","family":"Kopeinig","sequence":"additional","affiliation":[{"name":"United Nations Development Program (UNDP), Representation in Mexico, Montes Urales 440, Lomas de Chapultepec, 11000 Miguel Hidalgo, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"Cartus","sequence":"additional","affiliation":[{"name":"Woods Hole Research Center (WHRC), 149 Woods Hole Road, Falmouth, MA 02540, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Kellndorfer","sequence":"additional","affiliation":[{"name":"Woods Hole Research Center (WHRC), 149 Woods Hole Road, Falmouth, MA 02540, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rainer","family":"Ressl","sequence":"additional","affiliation":[{"name":"National Commission for the Knowledge and Use of Biodiversity (CONABIO),  Liga Perif\u00e9rico-Insurgentes Sur 4903, Parques del Pedregal, 14010 Tlalpan, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucio","family":"Santos","sequence":"additional","affiliation":[{"name":"National Forestry Commission (CONAFOR), Perif\u00e9rico Poniente 5360, San Juan de Ocot\u00e1n, Zapopan, 45019 Jalisco, Mexico"},{"name":"United Nations Development Program (UNDP), Representation in Mexico, Montes Urales 440, Lomas de Chapultepec, 11000 Miguel Hidalgo, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Schmidt","sequence":"additional","affiliation":[{"name":"National Commission for the Knowledge and Use of Biodiversity (CONABIO),  Liga Perif\u00e9rico-Insurgentes Sur 4903, Parques del Pedregal, 14010 Tlalpan, Mexico City, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2014,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"(2009).
