Aerophotogrammetry along a coast can be useful for:
- studying the evolution of the shore line;
- planning coastal defense projects and works;
- analyzing how harbours and other structures act for sand’s movement;
- defining nourishment;
- checking the granulometry of a beach;
- studying geomorphology and coastal habitats;
- evaluating the contribution of sediments from main rivers and minor streams, and how shoreline currents move them once out in the sea.
A dynamic environment, such as the coast, however, needs a lot of data acquired time over time.
For a long time and even after significant events and storms.
Drones and photogrammetric techniques support these studies with flights and surveys at predetermined time steps, on pre-programmed flight missions and with rather sustainable costs.
