P2P and Agent Service Based On-Line 3DGIS

摘要

Currently, the 3DGIS on the web can not meet the requirement of many applications because of the low network bandwidth, the large amount data involved, and the need of high speed of data transportation. To resolve the problems, in this paper, the on-line 3DGIS based on P2P agent distributed computing environment is proposed. We designed the tile-based 3D terrain and the mechanism of the distribution and management of 3DGIS data on P2P agent environment. We also proposed data searching and transmission algorithms for on-line 3DGIS. Finally, the data security mechanism of on-line 3DGIS is presented.
