Map updating and coastline control with very high resolution satellite images: application to Molise and Puglia coasts (Italy)

The very high-resolution satellite images are a useful tool both for map updating and environmental monitoring. Phenomena, with a detail of 0.5m up to 1m, could be observed. The coastal areas are quite critical and quickly evolving. QuickBird and Ikonos images are likely able to investigate coastal changes within 1m of accuracy. This paper deals with two experiments applied to the coastline control: the first one concerns the study of Molise coasts, while the second is related to the Puglia Region map updating.
