In this study, in order to carry out the vegetation evaluation, the conventional inverse problem methods weren't used from the remotely sensed image, but the vegetation environment model of forward direction processing with three-dimensional computer graphics (3D CG) was developed and is utilized for the complicated vegetation area. First, the measurement model of the vegetation region in the remotely sensed image was proposed, and the virtual space in vegetation area which placed the tree by 3D CG was made. Next, the vegetation region measurement model and the 3D CG virtual space in the vegetation area were linked, and measurement simulation for the remote sensing in the vegetation region was developed. Finally, the problem of vegetation evaluation by present remote sensing was examined as an analysis of developed measurement simulation.
