Abstract
This paper presents a new automatic system for fast generation of multiscale colour 2D and 3D satellite images and for online dynamic visualization of the 2D and 3D information of the areas of interest. Mediumresolution satellite images such as Landsat 7 and high-resolution satellite images such as Ikonos or QuickBird are the main data sources for the multi-scale 2D and 3D images. Since Landsat imagery has a global coverage and the Ikonos and QuickBird images can be acquired quickly for the areas of interest, the generation and online visualization of global colour 2D and 3D satellite images at different scales is possible. Ground objects from mountain ranges, such as Rocky Mountains, to individual family houses and trees can be dynamically visualized and analyzed in 2D and 3D through the Internet. The system presents a great potential for fast and effective visualizing, monitoring, and analyzing disaster situations in 2D and 3D within a short time period, which can provide decision makers with important information for emergency response and disaster management. The concept of the 3D satellite image generation and online dynamic visualization are presented in this paper. Some examples on the potential of using online 3D for disaster management are given.
