![]() Technology and interdisciplinarity will be therefore critical for the development of a holistic approach to understand our changing environments and design appropriate management measures accordingly.Ĭoastal zones are the interface between the terrestrial and marine environments and together with nearshore ones are affected by multiple physical processes that originate in both the terrestrial (i.e., fluvial) and marine (i.e., waves and tides) environments. Our review indicates that the realization of seamless DTMs appears to be the basic condition to operate a comprehensive integration of marine and terrestrial data sets, so far exhaustively achieved in very few case studies. ![]() Although efforts towards an innovative integration of geo-environmental data from above to underwater are still in their infancy, we have identified seven topics for which this integration could be of tremendous benefit for environmental research: (1) geomorphological mapping (2) Late-Quaternary changes of coastal landscapes (3) geoarchaeology (4) geoheritage and geodiversity (5) geohazards (6) marine and landscape ecology and (7) coastal planning and management. Undoubtedly new methods and techniques of offshore investigation adopted over the last 50 years and the latest advances in computer vision have played a crucial role in allowing a seamless combination of terrestrial and marine data. In addition, geoscientists are used to working on land or at sea independently, making the integration even more challenging. However, this practice is hardly implemented because of the high (or even prohibitive) survey costs required for submerged areas and the frequent low accessibility of shallow areas. ![]() A comprehensive understanding of environmental changes taking place in coastal regions relies on accurate integration of both terrestrial and submerged geo-environmental datasets.
