To prevent a wildfire progression and minimize its impact, Fuel Management Zones (FMZs) have been stipulated, by law, around buildings, settlements, along national roads, and other infrastructures. FMZs require monitoring of the vegetation condition to promptly proceed with the maintenance and cleaning of these zones. To improve FMZ monitoring, this paper proposes the use of satellite images, such as the Sentinel-1 and Sentinel-2, along with vegetation indices and extracted temporal characteristics (max, min, mean and standard deviation) associated with the vegetation within and outside the FMZs and to determine if they were treated. These characteristics feed machine-learning algorithms, such as XGBoost, Support Vector Machines, K-nearest neighbors and Random Forest. The results show that it is possible to detect an intervention in an FMZ with high accuracy, namely with an F1-score ranging from 90% up to 94% and a Kappa ranging from 0.80 up to 0.89.<\/jats:p>","DOI":"10.3390\/ijgi9090533","type":"journal-article","created":{"date-parts":[[2020,9,7]],"date-time":"2020-09-07T09:18:16Z","timestamp":1599470296000},"page":"533","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Assessment of Interventions in Fuel Management Zones Using Remote Sensing"],"prefix":"10.3390","volume":"9","author":[{"given":"Ricardo","family":"Afonso","sequence":"first","affiliation":[{"name":"Departamento de Inform\u00e1tica da Faculdade de Ci\u00eancias e Tecnologia and NOVA LINCS, Universidade Nova de Lisboa, Largo da Torre, 2825-149 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1411-3711","authenticated-orcid":false,"given":"Andr\u00e9","family":"Neves","sequence":"additional","affiliation":[{"name":"Departamento de Inform\u00e1tica da Faculdade de Ci\u00eancias e Tecnologia and NOVA LINCS, Universidade Nova de Lisboa, Largo da Torre, 2825-149 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Viegas Dam\u00e1sio","sequence":"additional","affiliation":[{"name":"Departamento de Inform\u00e1tica da Faculdade de Ci\u00eancias e Tecnologia and NOVA LINCS, Universidade Nova de Lisboa, Largo da Torre, 2825-149 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o","family":"Moura Pires","sequence":"additional","affiliation":[{"name":"Departamento de Inform\u00e1tica da Faculdade de Ci\u00eancias e Tecnologia and NOVA LINCS, Universidade Nova de Lisboa, Largo da Torre, 2825-149 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Birra","sequence":"additional","affiliation":[{"name":"Departamento de Inform\u00e1tica da Faculdade de Ci\u00eancias e Tecnologia and NOVA LINCS, Universidade Nova de Lisboa, Largo da Torre, 2825-149 Caparica, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3249-6229","authenticated-orcid":false,"given":"Maribel Yasmina","family":"Santos","sequence":"additional","affiliation":[{"name":"ALGORITMI Research Centre, University of Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,7]]},"reference":[{"key":"ref_1","unstructured":"Instituto da Conserva\u00e7\u00e3o da Natureza e das Florestas (2019). 8\u00b0 Relat\u00f3rio Provis\u00f3rio de Inc\u00eandios Rurais.
