MAPPING OF SECCHI DISK TRANSPARENCY DISTRIBUTIONS IN LAKE KASUMIGAURA AND OTHER LAKES WITH LANDSAT-3 MSS DATA

Application of Landsat imagery to regional-scale assessments of lake clarity.

A procedure that uses Landsat imagery to estimate Secchi disk transparency (SDT) of lakes was developed and applied to approximately 500 lakes with surface areas > 10 ha in the seven-county metropolitan area of Minneapolis and St. Paul, MN, USA, to assess spatial patterns and temporal trends in lake clarity. Thirteen Landsat MSS and TM images over the period 1973-1998 were used for the analysis...

Snowcover Mapping by Machine Processing of Skylab and Landsat Mss Data

SKYLAB and LANDSAT MSS data were analyzed using computer-aided analysis techniques (CAAT) developed at LARS. Results indicated that the middle infrared wavelength bands of the SKYLAB S-192 scanner would allow effective discrimination between snowcover and water-droplet clouds, whereas the limited spectral response of the LANDSAT-1 or 2 scanners do not allow such spectral discrimination. In the ...
