In this paper, a method of assessing water quality from satellite data is introduced. The composite pollution index (CPI) was calculated from measured chemical oxygen demand (COD) and nutrient concentration. The relationships between CPI and 240 band combinations of SeaWiFS water-leaving radiance were analyzed and the optimal band combination for estimating(More)

The positioning precision of the coding point center of image and the stability of the rotation pose of the image group are directly related to the accuracy and stability of the 3D coordinates of the subsequent space points. In this paper, a method of global positioning and global matching of the camera rotation posture is proposed. First we propose an(More)
