It is transparent, intended as human understandable as far as the employed criteria, and both knowledge and data-driven. It exploits remote sensing experts\u2019 interpretations to define the contributing factors from which partial evidence of the environmental status are computed by processing multispectral images. Furthermore, it computes an environmental status indicator (ESI) map by aggregating the partial evidence degrees through a learning mechanism, exploiting volunteered geographic information (VGI). The approach is capable of capturing the specificities of local context, as well as to cope with the subjectivity of experts\u2019 interpretations. The proposal is applied to map the status of standing water areas (i.e., water bodies and rivers and human-driven or natural hazard flooding) using multispectral optical images by ESA Sentinel-2 sources. VGI comprises georeferenced observations created both in situ by agronomists using a mobile application and by photointerpreters interacting with a geographic information system (GIS) using several information layers. Results of the validation experiments were performed in three areas of Northern Italy characterized by distinct ecosystems. The proposal showed better performances than traditional methods based on single spectral indexes.<\/jats:p>","DOI":"10.3390\/rs12030495","type":"journal-article","created":{"date-parts":[[2020,2,5]],"date-time":"2020-02-05T03:18:48Z","timestamp":1580872728000},"page":"495","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Knowledge and Data-Driven Mapping of Environmental Status Indicators from Remote Sensing and VGI"],"prefix":"10.3390","volume":"12","author":[{"given":"Alessia","family":"Goffi","sequence":"first","affiliation":[{"name":"IREA CNR, 20133 Milano, Italy"},{"name":"Terraria s.r.l., 20125 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6775-753X","authenticated-orcid":false,"given":"Gloria","family":"Bordogna","sequence":"additional","affiliation":[{"name":"IREA CNR, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5619-4305","authenticated-orcid":false,"given":"Daniela","family":"Stroppiana","sequence":"additional","affiliation":[{"name":"IREA CNR, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2156-4166","authenticated-orcid":false,"given":"Mirco","family":"Boschetti","sequence":"additional","affiliation":[{"name":"IREA CNR, 20133 Milano, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5477-3194","authenticated-orcid":false,"given":"Pietro Alessandro","family":"Brivio","sequence":"additional","affiliation":[{"name":"IREA CNR, 20133 Milano, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bordogna, G., Frigerio, L., Kliment, T., Brivio, P.A., Hossard, L., Manfron, G., and Sterlacchini, S.
