Abstract

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 seventies 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 2 MSS subscene acquired on July 1975. The newer image is an Envisat SAR image acquired on July 2003. We also used six Landsat TM and ETM images covering the period from 1975 to 2003. All the images covering the area of study have been geometrically corrected taking into account more than 100 ground control points distributed in whole images. The resembling method for warping the data was nearest neighborhood interpolation and the new pixel size for all the images was 30 meters. The general conclusion is that we can use satellite data from different sensors for the lake extent mapping and the environmental monitoring.
