Research On Space Geographic Information Systems-Based ArcGIS

With the advent of the information age, the space is forming based on three S (GPS (global positioning system), GIS (geographic information system), remote sensing (RS) and communications technology integration of spatial information of the earth.What we do space information system is based on the concrete embodiment of "digital earth" theory, remote sensing, gis, and global positioning system, broadband network, and the virtual simulation technology, such as construction of multitemporal, multi-scale, multi-resolution, seriation multi-source data of spatial information platform, the fusion of the political, economic, social, cultural, scientific aspects of information resources, hebei province and its related phenomenon of true unity and recreate the digital information resources, the highly integrated and sublimation.System using C/S and B/S structure of mixed mode, the server storage attribute data by ORACLE database management, the client data transmission to request through the network, server, database system, the corresponding results of data generated again returned to the client data.System using ArcObjects components and Microsoft.net VS development platform of 2003, with c # for programming language, for secondary development. The function definitions of GIS, using standard component interface standards of COM interface, and development tools and languages. Based on user needs according to the application for secondary development, can use all sorts of developing language (VB, Dephi, VC etc), even in a different function plugin using different language development. System design is a new application development framework model, system framework through simple custom integrate them into an organic whole.The system adopts the Oracle + ArcSDE used for data storage, Arc/results-related areas as a thing of data platform, the incoming data COM interface, ArcObjects adopts a system application development, realize the database interface, and later call and application system development.
