Abstract
Lefkas Island is situated in the Ionian Sea, Greece. The Ionian Sea presents a very big seismicity and the landslides phenomena are very often. As a result many landslides have been recorded on Lefkas Island during the last twenty-five years. Also the island suffers from summer forest fires and large rural areas have been burnt. In this paper a combined use of multitemporal and multisensor Remote Sensing data and GIS techniques for the environmental monitoring of Lefkas Island is presented. Multisensor and multitemporal satellite data were used for landslide detection and burnt area detection. The satellite data used cover the period from 1977 to 2003. More especially we have used: A Landsat MSS scene of 1977, A Lndsat TM scene of 1986, A Landsat TM scene of 1989, A Landsat TM scene of 2000, A Landsat ETM scene of 2000, An Aster Vnir scene of 2000, An Aster Vnir scene of 2003. All the images have been orthorectified and resampled to 30m pixel size. Then using different band ratios we have managed to locate the burnt areas and the areas damaged by landslides. All the results have been verified by in situ measurements using a GPS receiver. The classification results from the satellite data, the in situ measurements and all the necessary maps (topographic geological etc.) have been integrated in a GIS database.
