Vermetid gastropods are coastal habitat engineers which build biogenic platforms typical of
intertidal rocky shores of central and south-east of the Mediterranean. These bioconstructions
create a secondary habitat which increases resource availability and space for organisms, locally
transforming the environment and modifying coastal geomorphology.
Biological characteristics and physical structure of these bioconstructions are commonly studied
by field-based sampling. Nevertheless, a lot of time is required to collect data over large areas of
reef, field conditions can impair data collection and direct reef image interpretation may be a
challenge due to their intertidal position.
In this study, a small RPAS is used to describe the macrostructure of two vermetid reefs in
different areas: Capo Gallo (NW Sicily) and Favignana Island (W Sicily).
