Remote sensing is helpful to identify vegetation change in semi-arid wetlands and to assess wetland degradation. Remote sensing-based monitoring requires identification of the spectral characteristics of soils and vegetation and their correspondence with the vegetation cover and soil conditions. We studied the spectral characteristics of soils and vegetation of saline wetlands in Monegros, NE Spain, through field and satellite images. Radiometric and complementary field measurements in two field surveys in 2007 and 2008 were collected in selected sites deemed as representative of different soil moisture, soil color, type of vegetation, and density. Despite the high local variability, we identified good relationships between field spectral data and Quickbird images. A methodology was established for mapping the fraction of vegetation cover in Monegros and other semi-arid areas. Estimating vegetation cover in arid wetlands is conditioned by the soil background and by the occurrence of dry and senescent vegetation accompanying the green component of perennial salt-tolerant plants. Normalized Difference Vegetation Index (NDVI) was appropriate to map the distribution of the vegetation cover if the green and yellow-green parts of the plants are considered.<\/jats:p>","DOI":"10.3390\/rs8070590","type":"journal-article","created":{"date-parts":[[2016,7,13]],"date-time":"2016-07-13T09:48:45Z","timestamp":1468403325000},"page":"590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Analysis and Mapping of the Spectral Characteristics of Fractional Green Cover in Saline Wetlands (NE Spain) Using Field and Remote Sensing Data"],"prefix":"10.3390","volume":"8","author":[{"given":"Manuela","family":"Dom\u00ednguez-Beisiegel","sequence":"first","affiliation":[{"name":"Agrifood Research &amp; Technology Center of Aragon (CITA), EEAD-CSIC Associated Unit, Ave. Monta\u00f1ana 930, 50059 Zaragoza, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7467-4812","authenticated-orcid":false,"given":"Carmen","family":"Casta\u00f1eda","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental de Aula Dei, EEAD-CSIC, Ave. Monta\u00f1ana 1005, 50059 Zaragoza, Spain"}]},{"given":"Bernard","family":"Mougenot","sequence":"additional","affiliation":[{"name":"Centre d\u2019Etudes Spatiales de la Biosph\u00e8re, (CESBIO), Universit\u00e9 de Toulouse, CNES\/CNRS\/IRD\/UPS, 18 Av.
