抄録

Image analysis using airborn MSS data was made to investigate actual conditions of each mixel and calculate vegetation cover ratio in each mixel. The MSS data with 1.9m resolution used for the analysis was obtained in urban areas in the afternoon on a summer clear sky day. Spatial distribution, frequency and spectral characteristics of mixels were clarified, and correlation between the value of vegetation index and the vegetation cover ratio in a pixel was investigated. On the basis of above results, we proposed a method to calculate vegetation cover ratio, and verified the competency of the method against the other method with no consideration about mixel.
