The study on critical technique and applying solution of smart terminal spatial information processing

Spatial information processing is one of the important research contents in information technology. It is the major direction to combine geo-information technique and mobile communication technique in the spatial information processing. In this paper, we have thoroughly analyzed supporting techniques of mobile smart terminal spatial information processing system based on the spatial information's characters such as real-time, mass, distributing, complexity, variety, and so on, established a frame of smart terminal spatial information processing system, which is included by data layer, middle layer and presentation layer. Also we have investigated an organization scheme for mobile map document in intelligent terminal and carried out the system's systematic function design. Using Visual Studio 2005 as developing environment and ArcGIS Server 9.3 as spatial information service platform, managing space data based on ArcSDE and SQL Server 2005 and supporting by ArcGIS Mobile secondary development module, we have developed smart terminal spatial information prototype system supported with multi-consumer control. The system can implement spatial information collecting, storing, editing, visualizing, and bi-directional simultaneous with server, and so on.
