Unmanned aircraft systems (UASs) offer a viable and economical alternative to a conventional sensor and platform for acquiring high spatial and high temporal resolution data with high operational flexibility. Coastal wetlands are among some of the most challenging and complex ecosystems for land cover prediction and mapping tasks because land cover targets often show high intra-class and low inter-class variances. In recent years, several deep convolutional neural network (CNN) architectures have been proposed for pixel-wise image labeling, commonly called semantic image segmentation. In this paper, some of the more recent deep CNN architectures proposed for semantic image segmentation are reviewed, and each model\u2019s training efficiency and classification performance are evaluated by training it on a limited labeled image set. Training samples are provided using the hyper-spatial resolution UAS imagery over a wetland area and the required ground truth images are prepared by manual image labeling. Experimental results demonstrate that deep CNNs have a great potential for accurate land cover prediction task using UAS hyper-spatial resolution images. Some simple deep learning architectures perform comparable or even better than complex and very deep architectures with remarkably fewer training epochs. This performance is especially valuable when limited training samples are available, which is a common case in most RS applications.<\/jats:p>","DOI":"10.3390\/rs12060959","type":"journal-article","created":{"date-parts":[[2020,3,18]],"date-time":"2020-03-18T08:13:27Z","timestamp":1584519207000},"page":"959","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":84,"title":["Review and Evaluation of Deep Learning Architectures for Efficient Land Cover Mapping with UAS Hyper-Spatial Imagery: A Case Study Over a Wetland"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1427-6265","authenticated-orcid":false,"given":"Mohammad","family":"Pashaei","sequence":"first","affiliation":[{"name":"Department of Computing Sciences, Texas A&amp;M University-Corpus Christi, Corpus Christi, TX 78412, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9718-7518","authenticated-orcid":false,"given":"Hamid","family":"Kamangir","sequence":"additional","affiliation":[{"name":"Department of Computing Sciences, Texas A&amp;M University-Corpus Christi, Corpus Christi, TX 78412, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7996-0594","authenticated-orcid":false,"given":"Michael J.","family":"Starek","sequence":"additional","affiliation":[{"name":"Department of Computing Sciences, Texas A&amp;M University-Corpus Christi, Corpus Christi, TX 78412, USA"},{"name":"Conrad Blucher Institute for Surveying and Science, Texas A&amp;M University-Corpus Christi, Corpus Christi, TX 78412, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2954-2378","authenticated-orcid":false,"given":"Philippe","family":"Tissot","sequence":"additional","affiliation":[{"name":"Conrad Blucher Institute for Surveying and Science, Texas A&amp;M University-Corpus Christi, Corpus Christi, TX 78412, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Boon, M., Greenfield, R., and Tesfamichael, S.
