“…The proposed UAS protocol summarizes the parameters that affect the collection of reliable high-resolution images in the marine environment and can be used in a wide range of oceanographic applications. The parameters of the protocol have been grouped considering existing protocols for aerial photography [21,22], UAS limitations in marine applications [20] and personal experience in flight planning using UAS, in three main categories: (i) Morphology of the area, (ii) Environmental conditions, (iii) Flight parameters. Although the limitations of UAS data acquisition over the sea have been reported in many applications [22,24], it is the first time that a dedicated protocol for UAS data acquisition in coastal areas is presented.…”

“…However, the collection of reliable information in a coastal and marine environment is challenging due to several limitations related to weather conditions (e.g., wind speed, precipitation probability), oceanographic parameters (e.g., turbidity levels) and sea state conditions (e.g., wavy sea surface). These limitations that are prevailing in the area during a UAS flight affect the quality of the produced geoinformation (e.g., orthophoto-maps) [20]. Thus, the identification and categorization of the UAS limitations are essential for the collection of quality aerial data in marine applications using aerial systems.…”

Aerial surveys in coastal areas using Unmanned Aerial Vehicles (UAVs) present many limitations. 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.

Recently, remote sensing using survey-grade UAVs has been gaining tremendous momentum in applications for the coastal hydro-environment. UAV-based remote sensing provides high spatial and temporal resolutions and flexible operational availability compared to other means, such as satellite imagery or point-based in situ measurements. As strict requirements and government regulations are imposed for every UAV survey, detailed survey planning is essential to ensure safe operations and seamless coordination with other activities. This study established a comprehensive framework for the planning of efficient UAV deployments in coastal areas, which was based on recent on-site survey experiences with a portable unmanned aerial vehicle (pUAV) that was carrying a heavyweight spectral sensor. The framework was classified into three main categories: (i) pre-survey considerations (i.e., administrative preparation and UAV airframe details); (ii) execution strategies (i.e., parameters and contingency planning); and (iii) environmental effects (i.e., weather and marine conditions). The implementation and verification of the framework were performed using a UAV–airborne spectral sensing exercise for water quality monitoring in Singapore. The encountered challenges and the mitigation practices that were developed from the actual field experiences were integrated into the framework to advance the ease of UAV deployment for coastal monitoring and improve the acquisition process of high-quality remote sensing images.
