Research of Massive Data Storage and Transmission for Digital Earth System
摘要
Abstract
A method used in massive data storage and transmission is needed, which is based on quadtree, also digital earth developed independently takes advantage of the method timely. Mostly,designed the database for image and altitude datas,and proposed the network transport based on massive data. The experiment indicates that this method can meet the needs of real-time visualization,also,it brings advantage to ascertain the map areas in sight, which can greatly decrease the number of datas to rend,and improve the performance of the system. At last,the methods played an important role in digital earth system,and it is practical.关键词
