A New Storage Design of Distributed Geographic Information

Abstract:

In order to solve the storage problem of mass graphic data in web, an improved hierarchy of graphic objects is used in this paper. By building up layer object, the system can manage the data for different levels of abstraction. It is different from Object-Oriented Data Base (OODB) which used a relational table as an object to manage data. Uniform operations for the same terrain are offered. Using Object-based Storage Device (OSD) is advantaged at data transmission. The method of storing layer object in OSD is given in the paper. Empirical results show that the mechanism is well-suited to fetch detail data in web.
