Because this classification is frequently required to be completed within a specific time frame, performance is also essential. In this work, we propose a new method that creates synthetic images by extracting satellite data at the pixel level, processing all available bands, as well as their data distributed over time considering images from multiple dates. With this approach, data from images of Sentinel-2 are used by a deep convolutional network system, which will extract the necessary information to discern between different types of crops over a year after being trained with data from previous years. Following the proposed methodology, it is possible to classify crops and distinguish between several crop classes while also being computationally low-cost. A software system that implements this method has been used in an area of Extremadura (Spain) as a complementary monitoring tool for the subsidies supported by the Common Agricultural Policy of the European Union.<\/jats:p>","DOI":"10.3390\/rs13173378","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T23:25:50Z","timestamp":1629933950000},"page":"3378","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Crop Classification of Satellite Imagery Using Synthetic Multitemporal and Multispectral Images in Convolutional Neural Networks"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4116-6483","authenticated-orcid":false,"given":"Guillermo","family":"Siesto","sequence":"first","affiliation":[{"name":"Quercus Software Engineering Group, Universidad de Extremadura, 10003 C\u00e1ceres, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8639-3690","authenticated-orcid":false,"given":"Marcos","family":"Fern\u00e1ndez-Sellers","sequence":"additional","affiliation":[{"name":"Quercus Software Engineering Group, Universidad de Extremadura, 10003 C\u00e1ceres, Spain"}]},{"given":"Adolfo","family":"Lozano-Tello","sequence":"additional","affiliation":[{"name":"Quercus Software Engineering Group, Universidad de Extremadura, 10003 C\u00e1ceres, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"ref_1","unstructured":"European Union Commission (2021, February 23).
