Abstract
Lake Balaton is an important recreational area not only in Hungary but in Central-Europe as well. In the last decades due to increased tourism, industrial and agricultural activity the eutrophication of the lake is subject of serious considerations. The usual chlorophyll-a content measurements for the whole lake are rather expensive and time consuming and do not give enough information for an overall picture of water quality. A good correlation (r > 0.9) has been found between the reflectivities measured by Landsat MSS in the visible bands and the chlorophyll-a values derived from water samples (taken not exactly on the day of imaging) when the meteorological conditions between the date of imaging and sampling, and the sampling site selection were favourable. Based on this correlation the chlorophyll-a map of Lake Balaton is presented for a given date. The infrared bands of Landsat are useful to map the distribution and spreading of macrophytes in shallow waters, as Lake Velencei is. The conclusion is that Landsat data can be used to monitor lake water quality changes, but simultaneous calibration measurements on properly selected sampling sites are necessary.
