| In the dual context of coastal hazard intensification and the growing number of stakes exposed to these hazards, coastal observatories are in demand to provide a structured framework dedicated to long-term monitoring. This article describes the drone-based photogrammetry monitoring performed since 2006 on Porsmilin Beach (Brittany, France) in the framework of the DYNALIT (Littoral and Coastline Dynamics) observatory, focusing on data quality and the consistency of long-term time series under the influence of multiple technological evolutions: Unmanned Aerial Vehicles (UAV) platforms with the arrival of electric multirotor drones, processing tools with the development of structure-from-motion (SfM) photogrammetry, and operational modes of survey. A study... |

| JERICO, the European research infrastructure of coastal observatories (JERICORI) is an ocean observing system of systems, designed to provide high-quality data that are supporting knowledge development on the complex and often coupled physical, chemical and biological processes characterizing the coastal waters of Europe. JERICO-RI integrates several observing platform types i.e. fixed buoys, piles, moorings, drifters, Ferrybox, gliders, HF radars, coastal cable observatories and the associated technologies dedicated to the observation and monitoring of the European coastal seas. The RI is to serve both the implementation of European marine policies and the elucidation of contemporary and future key scientific questions. It therefore includes observations... |

| Under natural and anthropogenic pressure, the coastal regions are evolving rapidly (population growth, erosion, modification of services, etc.), and some of these changes increase their vulnerability. Monitoring the evolution of the coastal regions has thus become essential to understand how they respond to the various pressures and to define how their resilience could be increased. Among other outcomes, such monitoring should provide continuous, high-resolution data on the spatial and temporal evolution of the coastal areas, especially the shoreline zone. One appropriate way to acquire long, continuous, time series of data is to set up a permanent observatory in the zone to be monitored. This paper aims to provide recommendations and a methodological... |
