Abstract

With the rapid development of Earth observation technologies, raster data has become the main Geographic Information System (GIS) data source. GIS should be able to manage and process huge raster data sets. In this paper, the problem of 3-dimensional visualization of huge DEM data sets and its corresponding images data sets in GIS was addressed. A real-time delamination method based on raster characteristics of DEM and image data has been developed. A simple geometry algorithm was used to implement dynamic Level of Division (LOD) delamination of DEM and image data and to realize real-time 3-dimensional visualization of huge DEM and image data set based on RDBMS management. © Springer-Verlag 2002.
