Paper Abstract

A special airborne hyperspectral remote sensing flight test for Push Broom Hypersectral Imager (PHI) were executed in Huangpujiang river region of Shanghai in Oct, 2003, and the water sampling and water quality parameters analyzing experiments were carried out almost in-phrase. Linear retrieval models were built with the water quality parameters and field measuring spectral reflectivity, and these models were applied to retrieve the water quality from images. Seven water quality parameters were retrieved from the images, and the classification maps of five of these parameters were made from PHI images of Wusong mouth where the Huangpujiang River entered the Yangtze River, and the concentration of Suspended Sediments concentration and Turbidity degree were also retrieved, comparing with the actual measurement results, the retrieved classifications were reliable with the error less than one type, and the retrieved results of the suspended sediment and turbidity degree were accordance with the actually measured results.
