Abstract
Italian coasts are subjected to morphological modifications that in the last
decades have, in many cases, been the cause of considerable coast-line
withdrawal. A detailed cognizance on dynamics and relative consequences on
territory and environment is necessary to plan actions for limiting these events
and their impacts. Reconstruction of temporal shoreline changes can be realized
using historical and recent maps, remote sensed images and topographic survey
results. Because of the heterogeneity of these data, their different levels of
accuracy must be considered. In this paper one of the most emblematic Italian
shorelines affected by erosion, the Domitian shoreline located in Northern
Campania Region (South Italy), is considered. GIS environment is used to
compare ancient and recent maps as well as remote sensed images. Cartographic
layers include IGMI (Istituto Geografico Militare Italiano) products from 1876 to
1984, on a scale 1:25.000 or 1:50.000. Others are an aerial photo (1:10.000)
produced in 1998 and an IKONOS panchromatic image acquired in 2005.
Taking into account the heterogeneity of these documentations, to realise
comparisons of their contents, all layers are related to the same cartographic
datum (Gauss-Boaga Roma40), so a reconstruction of the coastal evolution from
1876 to 2005 is obtained.
Keywords: coastal erosion, GIS, historical maps, high resolution remote sensed
images, accuracy.
