Paper Abstract

GIS system takes on such new features as massive data increasing and spatial data model based on object-orient thought, which is a challenge to current storage architectures and data organization modes. Massive GIS requires high performance, cross-platform data sharing, excellent scalability and integral storage, searching of the massive spatial data. Aiming at these demands, this article discusses, analyzes the shortage of present storage modes and sequentially a new kind storage theory--Object-Based Storage (OBS) is introduced. we describe object-based storage in detail, stressing how it improves performance, data sharing, security and realize integrative storage, organization mode of data. Based on OBS, this article puts forward a new kind of storage model of GIS spatial data, which breaks through traditional organization and management modes of spatial data based on database or file system. The model implements data storage and management directly based on spatial object model from storage layer to user layer. Comparing with storage model, we conclude that GIS spatial data storage model based on OBS can meet well the demands of data storage and management of massive GIS.
