However, the need for detailed and accurate information in a marine environment has made UAVs very popular. The aim of this paper is to present a protocol which summarizes the parameters that affect the reliability of the data acquisition process over the marine environment using Unmanned Aerial Systems (UAS). The proposed UAS Data Acquisition Protocol consists of three main categories: (i) Morphology of the study area, (ii) Environmental conditions, (iii) Flight parameters. These categories include the parameters prevailing in the study area during a UAV mission and affect the quality of marine data. Furthermore, a UAS toolbox, which combines forecast weather data values with predefined thresholds and calculates the optimal flight window times in a day, was developed. The UAS toolbox was tested in two case studies with data acquisition over a coastal study area. The first UAS survey was operated under optimal conditions while the second was realized under non-optimal conditions. The acquired images and the produced orthophoto maps from both surveys present significant differences in quality. Moreover, a comparison between the classified maps of the case studies showed the underestimation of some habitats in the area at the non-optimal survey day. The UAS toolbox is expected to contribute to proper flight planning in marine applications. The UAS protocol can provide valuable information for mapping, monitoring, and management of the coastal and marine environment, which can be used globally in research and a variety of marine applications.<\/jats:p>","DOI":"10.3390\/rs11161913","type":"journal-article","created":{"date-parts":[[2019,8,19]],"date-time":"2019-08-19T10:10:14Z","timestamp":1566209414000},"page":"1913","source":"Crossref","is-referenced-by-count":36,"title":["A Protocol for Aerial Survey in Coastal Areas Using UAS"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-9864-8790","authenticated-orcid":false,"given":"Michaela","family":"Doukari","sequence":"first","affiliation":[{"name":"Department of Marine Sciences, University of the Aegean, 81100 Lesbos, Greece"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-1805-3528","authenticated-orcid":false,"given":"Marios","family":"Batsaris","sequence":"additional","affiliation":[{"name":"Department of Geography, University of the Aegean, 81100 Lesbos, Greece"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6464-2008","authenticated-orcid":false,"given":"Apostolos","family":"Papakonstantinou","sequence":"additional","affiliation":[{"name":"Department of Marine Sciences, University of the Aegean, 81100 Lesbos, Greece"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-1916-1600","authenticated-orcid":false,"given":"Konstantinos","family":"Topouzelis","sequence":"additional","affiliation":[{"name":"Department of Marine Sciences, University of the Aegean, 81100 Lesbos, Greece"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Hedley, J.D., Roelfsema, C.M., Chollett, I., Harborne, A.R., Heron, S.F., Weeks, S.J., Skirving, W.J., Strong, A.E., Eakin, C.M., and Christensen, T.R.L.
