Abstract The study evaluates the Earth Resources Technology Satellite One (ERTS-1; i.e., LANDSAT-1) multispectral scanner (MSS) as a means of estimating lacustrine trophic state. Numerical classificatory methods are employed to ascertain the trophic character of 100 lakes in Minnesota, Wisconsin, Michigan, and New York. Principal components analysis is used to derive a multivariate trophic state index (PCl) using the trophic indicators chlorophyll a, conductivity, inverse of Secchi depth, total phosphorus, an algal assay yield, and total organic nitrogen. A binary masking technique is used to extract lake-related MSS data from digital tapes (CCTs). MSS color ratio models are developed which give good estimates of Secchi depth and fair estimates of chlorophyll a levels. Trophic state, as defined by lake position on the first principal component axis (PCl), is predicted using MSS color ratio regression models.
