Figure 9 for transparency, chlorophyll-a, 
UV extinction and oxygen saturation, 
respectively. 
5. CONCLUSION 
As a result of this study, the following 
conclusions were obtained for water 
qualities of Lake Balaton. 
1) Transparency pattern extended along 
south shore of the lake. 
2) Chlorophyll-a, UV extinction and 
oxygen saturation patterns generally 
extended from the river mouth of 
Zala to north-east direction. 
Furthermore, for water quality moni 
toring using LANDSAT MSS data, the 
following conclusions are obtained. 
1) The strongest correlation was 
obserbed between MSS data and 
transparency among those fourteen 
items. 
2) Instead, no correlations were 
observed for suspended solid 
concentrations, water temperature 
and ratios of acid soluble 
magnesium and phosphorus. 
3) Mean values of 3x3 pixels window can 
be considered to be the most 
desirable signature. 
4) Although there are some reports 
about water quality monitoring using 
band to band ratios, e.g. band4 / 
band5, no special effect was 
recognized in this study.
