It is very important to monitor such wetlands to inform management on the status of these fragile ecosystems. This study aims to examine the applicability of TerraSAR-X quadruple polarimetric (quad-pol) synthetic aperture radar (PolSAR) data for classifying wetland vegetation in the Everglades. We processed  quad-pol data using the Hong &amp; Wdowinski four-component decomposition, which accounts for double bounce scattering in the cross-polarization signal. The calculated decomposition images consist of four scattering mechanisms (single, co- and cross-pol double, and volume scattering). We applied an object-oriented image analysis approach to classify vegetation types with the decomposition results. We also used a high-resolution multispectral optical RapidEye image to compare statistics and classification results with Synthetic Aperture Radar (SAR) observations. The calculated classification accuracy was higher than 85%, suggesting that the TerraSAR-X quad-pol SAR signal had a high potential for distinguishing different vegetation types. Scattering components from SAR acquisition were particularly advantageous for classifying mangroves along tidal channels. We conclude that the typical scattering behaviors from model-based decomposition are useful for discriminating among different wetland vegetation types.<\/jats:p>","DOI":"10.3390\/rs70708563","type":"journal-article","created":{"date-parts":[[2015,7,8]],"date-time":"2015-07-08T10:10:02Z","timestamp":1436350202000},"page":"8563-8585","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Evaluation of Polarimetric SAR Decomposition for Classifying Wetland Vegetation Types"],"prefix":"10.3390","volume":"7","author":[{"given":"Sang-Hoon","family":"Hong","sequence":"first","affiliation":[{"name":"Division of Polar Ocean Environment, Korea Polar Research Institute, 26 Songdomiraero, Yeonsugu, Incheon 406-840, Korea"},{"name":"Department of Marine Geosciences, University of Miami, 4600 Rickenbacker Causeway, Miami, FL 33149, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyun-Ok","family":"Kim","sequence":"additional","affiliation":[{"name":"Satellite Information Application Center, Korea Aerospace Research Institute, 169-84 Gwahakro, Yuseonggu, Daejeon 305-333, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shimon","family":"Wdowinski","sequence":"additional","affiliation":[{"name":"Department of Marine Geosciences, University of Miami, 4600 Rickenbacker Causeway, Miami, FL 33149, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emanuelle","family":"Feliciano","sequence":"additional","affiliation":[{"name":"Department of Marine Geosciences, University of Miami, 4600 Rickenbacker Causeway, Miami, FL 33149, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,7,7]]},"reference":[{"key":"ref_1","unstructured":"Center for International Forestry Research (CIFOR) (2012).
