Abstract
This paper deals with development of decision making tool for mapping of water quality Parameters of Hussainsagar lake of Hyderabad District, Telangana. Mapping was done using satellite data combined with measurement of selected sample points. Water quality data was collected for both pre-monsoon and postmonsoon seasons. The water quality parameters included, TS, DS, SS, pH, COD, BOD, DO, Chloride and TH. Using radiance data of pre-monsoon images and in situ measurement data of water quality parameters correlation were developed and selected most appropriate band combinations. With the help of these multiple water quality parameters obtained through laboratory analysis of water quality and preparation of digital cartographic maps depicting the water quality over the entire study area for both the seasons respectively.
