“…However, these activities require ongoing management to mitigate environmental, social and urban impacts. Decision makers can use drones as an assessment tool to improve coastal management decisions (Provost et al , 2019; Lu and Chyi, 2020). UAV technology can also provide access to marine and coastal ecosystems in inaccessible coastal areas (Niculescu et al , 2017), provide early detection of marine ingress blooms (Mcilwaine, Casado and Waine, 2022), monitor erosion in areas of intense tourism activity (Chapapría et al , 2022; García-Romero et al , 2019) and observe the positive sedimentary budgets for beaches (Provost et al , 2019).…”

Purpose Drones have become an important element within hospitality and tourism. The purpose of this study is to identify the corpus of knowledge and create a research agenda that establishes appropriate guidelines for future study of drone application in hospitality and tourism. Design/methodology/approach This work has been undertaken using a mixed-methods approach that combines quantitative and qualitative research and includes a review of the literature related to the study of drone use in hospitality and tourism. Findings The mixed-methods review identified gaps in the research, potential areas of study to enhance the scientific literature and potential uses of drones in tourism and hospitality for researchers, consumers and industry professionals. Originality/value This study makes an original contribution by establishing an integrated framework, which led to a synthesis of the research corpus and provided a holistic conceptualisation of the relationship between tourism and drones. In addition, the research agenda proposed will help boost and consolidate this emerging field of research.

“…Applications of UAV technology can contribute to integrated coastal zone management (ICZM) and achieve the UN sustainable development goals (SDGs) [49]. The dynamic evolution of coastal areas in different areas has been researched by using UAVs [50][51][52][53]. In this study, a combination of different data is used to obtain an interdisciplinary approach.…”

The concentration of the world’s population in coastal areas means an increase in pressure on the environment and coastal ecosystems. The impacts of climate change affect natural biophysical and ecological systems and human health. Research has been developed to create coastal monitoring with Unmanned Aerial Vehicles (UAVs) that allow data to be obtained and methodologies that integrate computer vision algorithms for 3D and image processing techniques for analysis, combined with maritime information. The Valencian oval is located on the Spanish Mediterranean coast and registers significant coastal erosion. It is a densely populated area, with high economic relevance and tourist activity. The main goals of the developed research in this coastal area include creating a methodology of data collection that identifies environmental indicators significant to community health and uses in the coastal areas, to test progression of interventions and to assess coastal erosion detection and monitoring. The final objective is to aid in decision-making and coastal management. Sediment characterization was obtained, and continuous maritime information was collected. The dynamic evolution of coastal areas was researched by using UAVs on the Spanish Mediterranean coast. This technique is suitable for measuring medium to small coastal changes. Flight planning was carried out using the grid mode and adapted to areas in order to obtain a homogeneous pixel size and precision. This monitoring program takes advantage of technological development with very low economic costs and is a good tool for making decisions that must be based on scientific information. With the monitoring work, an annual erosion between 12 and 6 m was detected. The monitoring program has evidenced the shoreline trend as a result of the impact of rigid structures, mainly ports and groins, in promoting down-drift erosion processes in the area.

“…Also, the contribution of Ground Control Points (GCPs) to such a survey is fundamental, because they increase the accuracy of the UAV imagery to centimeter level (Fallati et al, 2020;Lu et al, 2020). At least 5 to 10 GCPs, depending to the extension of the banquette, were used for each mission of this study.…”

Coastal environments and in particular beaches are valuable natural assets, offering a wide array of ecosystem services and economic benefits. In this study UAV technology with RTK-GPS is used in order to map in detail, the beach morphological characteristics, aiming to the impact of the presence of Posidonia οceanica beach-cast deposits. The principal aim of this research is to evaluate the relation between the banquettes and the sediments, as well as the banquette's significance concerning the beach protection. Particularly, the distinctive goals are: a) to identify the differences in volume, shape and area covered by the banquettes, and b) to analyze the relationship between banquette deposition and the changes of the sedimentary budget. The presence of the fine-grained sediments and the calculation of the sediment budget enclosed in the total volume of the banquette (692.57±8.3m3 (Mission 2)) will re-evaluate their role concerning the coastline protection.
