This study reviewed 112 studies on fusing optical and radar data, which offer unique spectral and structural information, for land cover and use assessments. Contrary to our expectations, only 50 studies specifically addressed land use, and five assessed land use changes, while the majority addressed land cover. The advantages of fusion for land use analysis were assessed in 32 studies, and a large majority (28 studies) concluded that fusion improved results compared to using single data sources. Study sites were small, frequently 300\u20133000 km                                                      2                                  or individual plots, with a lack of comparison of results and accuracies across sites. Although a variety of fusion techniques were used, pre-classification fusion followed by pixel-level inputs in traditional classification algorithms (e.g., Gaussian maximum likelihood classification) was common, but often without a concrete rationale on the applicability of the method to the land use theme being studied. Progress in this field of research requires the development of robust techniques of fusion to map the intricacies of land uses and changes therein and systematic procedures to assess the benefits of fusion over larger spatial scales.<\/jats:p>","DOI":"10.3390\/rs8010070","type":"journal-article","created":{"date-parts":[[2016,1,18]],"date-time":"2016-01-18T10:58:33Z","timestamp":1453114713000},"page":"70","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":566,"title":["A Review of the Application of Optical and Radar Remote Sensing Data Fusion to Land Use Mapping and Monitoring"],"prefix":"10.3390","volume":"8","author":[{"given":"Neha","family":"Joshi","sequence":"first","affiliation":[{"name":"Department of GeoSciences and Natural Resource Management, University of Copenhagen, Copenhagen 1165, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Baumann","sequence":"additional","affiliation":[{"name":"Geography Department, Humboldt-University Berlin, Unter den Linden 6, Berlin 10099, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Ehammer","sequence":"additional","affiliation":[{"name":"Department of GeoSciences and Natural Resource Management, University of Copenhagen, Copenhagen 1165, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3067-4527","authenticated-orcid":false,"given":"Rasmus","family":"Fensholt","sequence":"additional","affiliation":[{"name":"Department of GeoSciences and Natural Resource Management, University of Copenhagen, Copenhagen 1165, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth","family":"Grogan","sequence":"additional","affiliation":[{"name":"Department of GeoSciences and Natural Resource Management, University of Copenhagen, Copenhagen 1165, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Hostert","sequence":"additional","affiliation":[{"name":"Geography Department, Humboldt-University Berlin, Unter den Linden 6, Berlin 10099, Germany"},{"name":"Integrative Research Institute on Transformations of Human-Environment Systems (IRI THESys), Humboldt-University Berlin, Unter den Linden 6, Berlin 10099, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Jepsen","sequence":"additional","affiliation":[{"name":"Department of GeoSciences and Natural Resource Management, University of Copenhagen, Copenhagen 1165, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Kuemmerle","sequence":"additional","affiliation":[{"name":"Geography Department, Humboldt-University Berlin, Unter den Linden 6, Berlin 10099, Germany"},{"name":"Integrative Research Institute on Transformations of Human-Environment Systems (IRI THESys), Humboldt-University Berlin, Unter den Linden 6, Berlin 10099, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1047-9794","authenticated-orcid":false,"given":"Patrick","family":"Meyfroidt","sequence":"additional","affiliation":[{"name":"F.R.S.-FNRS, Brussels 1000, Belgium"},{"name":"Earth and Life Institute (ELI), Universit\u00e9 Catholique de Louvain, Louvain-La-Neuve 1348, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5690-4055","authenticated-orcid":false,"given":"Edward","family":"Mitchard","sequence":"additional","affiliation":[{"name":"School of GeoSciences, University of Edinburgh, Edinburgh EH9 3FF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4327-4349","authenticated-orcid":false,"given":"Johannes","family":"Reiche","sequence":"additional","affiliation":[{"name":"Laboratory of Geo-Information Science and Remote Sensing, Wageningen University, Droevendaalsesteeg 3, Wageningen 6708 PB, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1802-0128","authenticated-orcid":false,"given":"Casey","family":"Ryan","sequence":"additional","affiliation":[{"name":"School of GeoSciences, University of Edinburgh, Edinburgh EH9 3FF, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bj\u00f6rn","family":"Waske","sequence":"additional","affiliation":[{"name":"Institute of Geographical Sciences, Freie Universit\u00e4t Berlin, Malteserstr. 74 - 100, Berlin 12249, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"20666","DOI":"10.1073\/pnas.0704119104","article-title":"The emergence of land change science for global environmental change and sustainability","volume":"104","author":"Turner","year":"2007","journal-title":"Proc.
