With the advent of flex fuel cars in 2003 the sugarcane area almost doubled over the last decade in the South-Central region of Brazil. Using remote sensing images, the sugarcane cultivation area was annually monitored and mapped between 2003 and 2012, a period of major sugarcane expansion. The objective of this work was to assess the thematic mapping accuracy of sugarcane, in the crop year 2010\/2011, with the novel approach of developing a web platform that integrates different spatial and temporal image resolutions to assist interpreters in classifying a large number of points selected by stratified random sampling. A field campaign confirmed the suitability of the web platform to generate the reference data set. An overall accuracy of 98% with an area estimation error of \u22120.5% was achieved for the sugarcane map of 2010\/11. The accuracy assessment indicated that the map is of excellent quality, offering very accurate sugarcane area estimation for the purpose of agricultural statistics. Moreover, the web platform showed to be very effective in the construction of the reference dataset.<\/jats:p>","DOI":"10.3390\/rs4103201","type":"journal-article","created":{"date-parts":[[2012,10,22]],"date-time":"2012-10-22T05:32:03Z","timestamp":1350883923000},"page":"3201-3214","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["A Web Platform Development to Perform Thematic Accuracy Assessment of Sugarcane Mapping in South-Central Brazil"],"prefix":"10.3390","volume":"4","author":[{"given":"Marcos","family":"Adami","sequence":"first","affiliation":[{"name":"Remote Sensing Division (DSR), National Institute for Space Research (INPE), Av. dos Astronautas, 1758, S\u00e3o Jos\u00e9 dos Campos-SP, 12227-010, Brazil"}]},{"given":"Marcio Pupin","family":"Mello","sequence":"additional","affiliation":[{"name":"Remote Sensing Division (DSR), National Institute for Space Research (INPE), Av. dos Astronautas, 1758, S\u00e3o Jos\u00e9 dos Campos-SP, 12227-010, Brazil"}]},{"given":"Daniel Alves","family":"Aguiar","sequence":"additional","affiliation":[{"name":"Remote Sensing Division (DSR), National Institute for Space Research (INPE), Av. dos Astronautas, 1758, S\u00e3o Jos\u00e9 dos Campos-SP, 12227-010, Brazil"}]},{"given":"Bernardo Friedrich Theodor","family":"Rudorff","sequence":"additional","affiliation":[{"name":"Remote Sensing Division (DSR), National Institute for Space Research (INPE), Av. dos Astronautas, 1758, S\u00e3o Jos\u00e9 dos Campos-SP, 12227-010, Brazil"}]},{"given":"Arley Ferreira de","family":"Souza","sequence":"additional","affiliation":[{"name":"Remote Sensing Division (DSR), National Institute for Space Research (INPE), Av. dos Astronautas, 1758, S\u00e3o Jos\u00e9 dos Campos-SP, 12227-010, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2012,10,19]]},"reference":[{"key":"ref_1","unstructured":"FAO (Food and Agriculture Organization of the United Nation) Available online: http:\/\/faostat.fao.org (accessed on 9 April 2012)."},{"key":"ref_2","unstructured":"IBGE (Instituto Brasileiro de Geografia e Estat\u00edstica) Available online: http:\/\/www.sidra.ibge.gov.br (accessed on 20 January 2012)."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"808","DOI":"10.1126\/science.1137013","article-title":"Ethanol for a sustainable energy future","volume":"315","author":"Goldemberg","year":"2007","journal-title":"Science"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"655","DOI":"10.1016\/j.energy.2008.11.001","article-title":"Can Brazil replace 5% of the 2025 gasoline world demand with ethanol?","volume":"34","author":"Leite","year":"2009","journal-title":"Energy"},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"582","DOI":"10.1016\/j.biombioe.2007.12.006","article-title":"Green house gases emissions in the production and use of ethanol from sugarcane in Brazil: The 2005\/2006 averages and a prediction for 2020","volume":"32","author":"Macedo","year":"2008","journal-title":"Biomass Bioener"},{"key":"ref_6","doi-asserted-by":"crossref","first-page":"961","DOI":"10.1021\/es802681k","article-title":"Biofuels, land use change, and greenhouse gas emissions: Some unexplored variables","volume":"43","author":"Kim","year":"2009","journal-title":"Environ.
