Abstract

A method has been developed to derive both height and motion from satellite images using a purely geometrical technique. This is a combination of using stereo to measure height by viewing cloud from two view point and using several images in time to measure motion of clouds. The method requires that the cloud be viewed from two or more different perspectives with at least two of the views being at different times. With the new method time coincidence is a disadvantage, and higher accuracy is obtained when all views are at different times. For height verification, improvements have been made in the cloud height by shadow method. Accuracies of better than 1 km height and 0.5 m/sec are typical of the results.
