Abstract
Using the limnological data of Lake Kasumigaura on July 29, 1976 as ground truth data, several numerical analyses are progressed on the LANDSAT MAP CCT which are transformed from the original LANDSAT MSS CCT.
Secchi disc transparency and chlorophill-a density maps which estimated around the whole lake water area are made by several prediction equations based on the multiple and single regression equations between observation data and LANDSAT MAP CCT data. These maps are possible to overlay on topographic maps and two digital color classification maps were made by a direct photoprinter from the same CCT.
Above mentioned numerical analyses and digital color maps are effective in the eutrophication map making based on some water quality indices (Secchi disc transparency etc.) to understand the areal pattern of the lake eutrophication phenomena.
