Environmental Monitoring of Lake Distos in Central Evia, Greece Using Multitemporal and Multisensor Remote Rensing Data

摘要

Lake Distos is situated Central Evia, Greece near to the Aliveri city. An ancient city was has been built at the shore of the lake. During the sixties a big part of the lake has been drained. As a result the lake's extent varies during the year. It covers a small area during the summer period and floods a quite big area during the winter. The objective of this study was to process multitemporal and multisensor satellite data in order to monitor the changes of the lake extent and the environmental consequences. In order to detect those changes we used multitemporal and multisensor satellite images. The former image that we used is a Landsat 1 MSS subscene acquired on July 1975. The newer image is an Envisat SAR image acquired on October 2003. We also used Landsat TM and ETM images covering the period from 1977 to 2003. The general conclusion is that we can use satellite data from different sensors for the lake extent mapping and the environmental monitoring.
