Study on Feasibility of Computer Graphic Use in Landscape Assessment of Hilly Land

The purpose of this study was to examine the feasibility of introducing computer graphics (CG) at each of three levels of landscape assessment, and the issues arising from its introduction. This was based on the idea that it is important to carry out landscape assessments as an analysis of a series of three levels-the regional level, to analyze the spatial structure of the region; the district level, to analyze the elevation, and spot level, to analyze the design of the site. The results showed that application of CG was extremely effective on all three levels. At the regional level, CG was valuable as a visual analytical method to examine the visibility of various elements; at the district level, it was extremely effective as a way to identify the effect on the view of changes of perspective; at the spot level, it was possible to carry out a landscape simulation, which served as a tool for examining measures to preserve the landscape, taking into consideration the growth of trees and shrubs and properties of forests
