New technologies for the detection
of natural and anthropic features
in coastal areas

Some results of the sub project GE.RI.N (Natural Resources Management) conducted in the Marine Protected
Area of Egadi Islands (Western Sicily) are presented. Coastal and seafloor morphology has been investigated
integrating different data sources and using remote sensing data acquired by the Ministry of Environment during
the MAMPIRA Project. This approach allowed us to recognize the real extent and distribution of several rocky
outcrops emerging from the sandy bottom, south of Favignana Island (known as “I Pali”), and the anthropogenic
features generated by the effects of traps, trawling and anchor on the Posidonia oceanica meadow that,
within the Egadi Archipelago, is the largest in the Mediterranean Sea [1] (www.ampisoleegadi.it). Unpublished
and detailed characterization of the seafloor and assessment of human impacts are the main results of the present
study, which demonstrate how remote sensing technologies have a great potential and relevant management
implication for Marine Protected Areas and the preservation of emerged and submerged environment
