Visual Effect Enhancement in Computer-Aided Hill-Shading

  • Analyzing the basic principle of automatic hill-shading and methods for enhancing the 3D expression of relief in traditional hill-shading,exposure and slope are considered to be important factors to the 3D expression of hill-shading.A proper change to gradient or grayness according to slope and exposure can be helpful to improve visual effect of hill-shading map.Two methods are introduced to modify gradient and grayness in computer-aided hill-shading.Practices prove that these methods are effective.
