Variazioni spazio-temporali della linea di costa molisana desunte dall’analisi multitemporale di immagini Landsat

In order to do such assessment, Remote sensing tecniques are used with a specific application, which permit to classify changes of coastline through the comparison of several Landsat images in the period 1975-2004. The classified data are analyzed with the aid of a GIS software, thus surfaces in erosion or in accretion are evaluated in the fixed range of time. From the obtained results the coastline moved backward up to 260 m (erosion), in correspendence of the mouth of Biferno River, and more forward in the strech at the south of the harbor of Termoli. The mean rate of the erosion/accretion is also evaluated for any strech of the examined coast. The whole dataset of results is perfectly comparable with literature data coming from independent surveys.
