Abstract
There has been a great development in Wireless GIS (WGIS) new century. Spatial data transferring and storage in GIS is developed from wired to wireless network. This paper first briefly introduces the technologies and strategies of spatial data transferring and storing in distributed Wireless GIS. Second, the schemes of spatial data transferring modes in wireless GIS for improving the network transfer rates is introduced emphatically, and the distributed transferring process technology of GIS spatial data are also discussed. Based on these, we present the storage strategies in wireless database, and introduce mobile computing conception and three-tiers wireless replication database. Here, we emphasizes on dynamic replication strategies and methods in wireless environment. Finally, we compare several of data storage strategies in WGIS databases and the dynamic multi-tiers replication strategy is proposed for wireless database storage.
