The Design And Development Of Chinese Provincial Economic Data Web Services Platform

In recent years, as Web technology development and GIS technology continues to mature, will GIS powerful spatial analysis function and Web technology with the birth of the development of GIS WebGIS has become the hotspot in the process, it can solve traditional problems such as GIS information is not Shared and its application field, also more and more widely. At present, China's rapid economic development, the provinces are using its geographical advantages developing regional economy, people on China's economy research has not only stay in the economic data, geographic information elements into the economic research on the Internet, and can realize information interaction and sharing has become a trend. Therefore, according to the research on economic data WebGIS data sharing service platform for the design and development of the research development and application of WebGIS practical significance.This research data sharing system is combined Chinese economic data used to provide a data sharing network service platform, throughout the development and design, fully understand the process of WebGIS in various fields of applications, through the analyses and compares the WebGIS several developing mode, choose the most suitable for data sharing platform development use B/S development mode, and then in learning the Chinese economic data analysis, based on the characteristics of data sharing platform thoroughly discusses about data management and release all the technique, Such as GIS technology, Web technology, database technology, Sliverlight technology, etc. Comparison of several mainstream at home and abroad, the application of WebGIS development platform, key research ESRI company ArcGIS Server application platform, according to the characteristics of data sharing platform put forward the presentation layer, the application layer, data layer by layer 3 frame, will ArcSDE and SQL-Server2005 management spatial data and economic data.The results show that, using ArcSDE and SQL-Sever2005 economic management and the spatial database, using Sliverlight development client and application of B/S structure model based on three layers of the Chinese provincial Sever ArcGIS regional economic network Shared services platform, can effective spatial data into economic data study, improve accuracy and timeliness of the data, accord with current people to study economic development combines the geographical elements required, also can realize the data sharing.
