Performance Analysis of an Altimetric Data Processing Methodology Applied to Three-dimensional Terrain Visualization

Abstract

Three-dimensional terrain visualization on computerized environment is usually associated to real time response capabilities. The predominant factor for an adequate performance for this kind of application, when considering desktop computers or portables, is the video board efficiency for drawing activities. In these applications, the process through which the cartographic data are prepared becomes a preponderant feature. This article presents a performance analysis based on the results obtained by an altimetric data pre-processing methodology in order to make possible its use on terrain visualization applications.
