The Global Human Settlement Layer (GHSL) is a project funded by the European Commission, Joint Research Centre, which aims at providing scientific methods and systems for reliable and automatic mapping of built-up areas from remote sensing data. In the frame of the GHSL, the opportunities offered by the recent availability of Sentinel-2 data are being explored using a novel image classification method, called Symbolic Machine Learning (SML), for detailed urban land cover mapping. In this paper, a preliminary test was implemented with the purpose of: (i) assessing the applicability of the SML classifier on Sentinel-2 imagery; (ii) evaluating the complementarity of Sentinel-1 and Sentinel-2; and (iii) understanding the added-value of Sentinel-2 with respect to Landsat for improving global high-resolution human settlement mapping. The overall objective is to explore areas of improvement, including the possibility of synergistic use of the different sensors. The results showed that noticeable improvement of the quality of the classification could be gained from the increased spatial detail and from the thematic contents of Sentinel-2 compared to the Landsat derived product as well as from the complementarity between Sentinel-1 and Sentinel-2 images.<\/jats:p>","DOI":"10.3390\/rs8040299","type":"journal-article","created":{"date-parts":[[2016,4,1]],"date-time":"2016-04-01T10:31:20Z","timestamp":1459506680000},"page":"299","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":171,"title":["Assessment of the Added-Value of Sentinel-2 for Detecting Built-up Areas"],"prefix":"10.3390","volume":"8","author":[{"given":"Martino","family":"Pesaresi","sequence":"first","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]},{"given":"Christina","family":"Corbane","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]},{"given":"Andreea","family":"Julea","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]},{"given":"Aneta","family":"Florczyk","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]},{"given":"Vasileios","family":"Syrris","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]},{"given":"Pierre","family":"Soille","sequence":"additional","affiliation":[{"name":"European Commission, Joint Research Center, Institute for Protection and Security of the Citizen, Global Security and Crisis Management Unit, Via Enrico Fermi 2749, I-21027 Ispra, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2016,4,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.isprsjprs.2015.01.001","article-title":"Global land cover mapping using Earth observation satellite data: Recent progresses and challenges","volume":"103","author":"Ban","year":"2015","journal-title":"ISPRS J.
