The research on realization of relief shading based on slope and aspect

CHEN Yan-li,LI Shao-mei(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
This paper calculated the slope and aspect of grid point using regular grid DEM ,and researched making process of relief shading based on slope and aspect,The research completed relief shading based on slope and aspect by choosing right algorithm of slope and aspect、lighting model and interpolation arithmetic in process.
