Abstract
In order to solve the problem that traditional Geographic Information System(GIS) can not run well offline, this paper uses native storage and proposes a scheme called quad tree file system, which is based on quad tree index, and it prevents the storage from the shortcoming using windows file system. The main function includes inserting, reading, querying and deleting, it encrypts the data using simple method, which improves the data security. Experimental results show that the scheme is better than Windows file system for storing native data.
