The Research And Development Of Hydrogeological Information System Of Xinzhou City Based On WebGIS

Water resources are closely related to human life,the hydrogeological conditions in China are complex,the information quantity is numerous and jumbled,using the network and geographic information technology to develop the hydrogeological information system,so as to provide support tools for the management of hydrogeological data and information,to realize the dynamic updating of the hydrogeological map and the hydrogeological information,and share the hydrogeological information in different regions at real-time,improve the efficiency of hydrogeological work,in order to guide the rational development of water resources.This research mainly uses the Visual Studio 2013 and Arc GIS Sever 10.2 as development platform,based on Arc SDE 10.2 and SQL Server 2008 database platform,using B / S structure,using the Java Script programming language,combined with HTML,CSS,AJAX,DOM,Dojo,j Query web development technology and the ADO.Net technique,through the server API to access the Arc GIS sever,resources provided by Arc GIS sever release to the web,to develope Xinzhou City hydrogeological information system based on the data of Web GIS Xinzhou City hydrogeological.The main research results are as follows:(1)The overall design of the system is completed.Through the survey and analysis,choose system development platform and development environment,design the security of the system.And select three layer network architecture,with resource layer,application service layer and representation layer.(2)The design of the system database.The system database includes the spatial database constructed by Arc SDE 10.2 and the attribute database established by Server SQL 2008,and the connection between the two kinds of database is established to realize the unified management of spatial data and attribute data.(3)The development and implementation of the system.Based on the data of Xinzhou City hydrogeological,and using network technology and geographic information technology,the function such as presentation of information,drawing graph,map output and printing,information query,database crud,monitoring data of dynamic update,and map distance to measure the area and buffer area analysis,statistical analysis,stack analysis device analysis function in web user management,map and hydrological geological thematic map browsing are realized.
