An Accuracy Model of DEM Terrain Representation Based on Scatterplot Matrices and Regression Analysis

QI Xiaofei;WANG Guangxia;MA Jun;WANG Fuqiang;Institute of Geography Spatial Information,Information Engineering University;61363Troops;78138Troops;  
Visualization is an effective method for analyzing correlation information between multivariate data.We built a multivariate data model statistically through a multivariate regression model based on scatter plot matrices.Next,we developed a formulae including terrain representation error,resolution,relative height,and a concave-convex coefficient and validated it through experimentation The experiments with this proposed formulae show that it is highly effective.
