In general, the approach relies on a change detection analysis applied on pre- and post-event images. This change detection analysis usually is carried out by comparing the values of specific spectral indices such as: NBR (normalised burn ratio), BAI (burn area index), MIRBI (mid-infrared burn index). However, some potential sources of error arise, particularly when near-real-time automated approaches are adopted. An automated approach is mandatory when the burnt area monitoring should operate systematically on a given area of large size (country). Potential sources of errors include but are not limited to clouds on the pre- or post-event images, clouds or topographic shadows, agricultural practices, image pixel size, level of damage, etc. Some authors have already noted differences between global databases of burnt areas based on satellite images. Sources of errors could be related to the spatial resolution of the images used, the land-cover mask adopted to avoid false alarms, and the quality of the cloud and shadow masks. This paper aims to compare different burnt areas datasets (EFFIS, ESACCI, Copernicus, FIRMS, etc.) with the objective to analyse their differences. The comparison is restricted to the Italian territory. Furthermore, the paper aims to identify the degree of approximation of these satellite-based datasets by relying on ground survey data as ground truth. To do so, ground survey data provided by CUFA (Comando Unit\u00e0 Forestali, Ambientali e Agroalimentari Carabinieri) and CFVA (Corpo Forestale e Vigilanza Ambientale Sardegna) were used. The results confirm the existence of significant differences between the datasets. The subsequent comparison with the ground surveys, which was conducted while also taking into account their own approximations, allowed us to identify the accuracy of the satellite-based datasets.<\/jats:p>","DOI":"10.3390\/rs16010042","type":"journal-article","created":{"date-parts":[[2023,12,21]],"date-time":"2023-12-21T10:53:52Z","timestamp":1703156032000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Progress and Limitations in the Satellite-Based Estimate of Burnt Areas"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6108-9764","authenticated-orcid":false,"given":"Giovanni","family":"Laneve","sequence":"first","affiliation":[{"name":"Scuola di Ingegneria Aerospaziale, Sapienza University of Rome, 00138 Rome, Italy"}]},{"given":"Marco","family":"Di Fonzo","sequence":"additional","affiliation":[{"name":"Comando Unit\u00e0 Forestali Ambientali e Agroalimentari Carabinieri, 00184 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9946-1303","authenticated-orcid":false,"given":"Valerio","family":"Pampanoni","sequence":"additional","affiliation":[{"name":"Scuola di Ingegneria Aerospaziale, Sapienza University of Rome, 00138 Rome, Italy"}]},{"given":"Ramon","family":"Bueno Morles","sequence":"additional","affiliation":[{"name":"Scuola di Ingegneria Aerospaziale, Sapienza University of Rome, 00138 Rome, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"116","DOI":"10.1071\/WF07049","article-title":"Fire intensity, fire severity and burn severity: A brief review and suggested usage","volume":"18","author":"Keeley","year":"2009","journal-title":"Int.
