Oceans and seas are crucial components of the climate system and valuable assets for human activities. Natural and anthropogenic forcing are primary drivers of marine pollution, leading to water quality degradation and posing direct threats to ecosystems. In recent decades, in line with the European Marine Strategy Framework Directive (MSFD), researchers, along with public and private institutions, have increasingly focused on developing innovative monitoring strategies for coastal environments to promote sustainable use. In fact, the synoptic-scale variability and dynamic nature of these environments require alternatives to traditional in-situ data sampling approaches. Developed at DIGISKY S.R.L., this thesis aims to illustrate the pivotal role of various remote sensing technologies in supporting coastal monitoring programs, processing satellite and aerial photogrammetric data, and delivering relevant georeferenced products.
