Located at the entrance of Ría de Vigo, Illas Cíes stand out for its asymmetrical profile, with two very different facades. On the western facade, cliffs dominate reaching over 160 m of altitude and 80º slope. The eastern facade is characterized by a smooth topography with slopes that do not reach 75º and heights not exceeding 150 m chaining cliffs, platforms, beaches, sand dunes and beaches of ...

With the aim to become a better characterization of the types of coast have generated various layers of information through a GIS from digital models 2 m resolution, which allowed us to distinguish 5 types of cliffs and beach-dune systems.
The analysis has allowed a precise geomorphological cartography, identifying not only the most extensive landforms but also those minor case of coastal platforms or fossilized sectors by ancient sedimentary deposits. To do this we used a GPS to centimeter accuracy.
