Adaptive rendering system of large scale 3D-terrain data for streaming services

초록

The development of satellite image technologies and the expansion of internet infrastructure have encouraged various satellite image services in the web environment However, most of these services are still based on the low-resolution satellite images and Digital Elevation Model data. In this paper, we propose the adaptive rendering system which renders high-spatial resolution satellite images for proficient streaming services in the web. And we have implemented some modules for our proposed approaches. A raw data processing module divides high-capacity satellite images and DEM data systematically to build the basic data and 3-dimensional topographic rendering module receives its data via the streaming module and minimizes data for real time rendering. Our proposed techniques have been applied to the real satellite images of Mt Bukhan and have shown to efficiently solve graphical issues in real time processing of large geographical area. ©2013 International Information Institute.
