Terrain Matching for Three-dimensional Visualization of Two-dimensional GIS Vector Data

Published:
Abstract: A fast terrain matching method for 3D visualization of 2D GIS vector data was proposed. 3D terrain features based on vector information were firstly classified by its characteristic,thcn either feature adjusting or terrain adjusting method was chosen for matching of features and terrain. Feature adjusting method adjusted the position and gesture of features in real-time,terrain adjusting method applied terrain deformation to vector constrained field based on different distance measurement. I}he algorithms also dealt with some special cases such as low resolution of terrain dataset and multi-vector restriction applied to the same area. Experimental results show that our method could meet the requirement of terrain matching effectively for 3D terrain features based on vector data including points,lines and surfaces with high visual quality.
