CONSTRUCTION OF THE VISUALZATION MODEL BY LANDSCAPE COGNITION USING THE 3-DIMENSIONAL SHADE PICTURE(Information Systems Technology)

Abstract

This paper is made into the object of analysis on the coastal fishing villages in which the sea, a town, and a mountain are realized in one, and has complicated geographical feature. A visible space is set up based on "3D geographical feature model using the GIS data by DEM (Degital Elevation Model)", and "a spread of light which applied the inverse-square damping which is approximation to man's visual recognition." The usefulness of the shade picture reflecting the 3-dimensional space information acquired by that is considered.
