Research And Development Of Geohazards Online Information Platform In Guizhou Province Based On ADF

Guizhou Province frequent geological disasters, resulting in a large number ofcasualties and property loss, and the lack of unified and efficient geological disastersdatabase system and a set of geological disasters spatial data display, editing,information inquiry, statistics, focusing on demonstration area thematic showone of thegeological hazard online information platform, and this high-quality data managementand a more in-depth work carried out is essential.The paper‘s the overall goal is establishing the online information platform ofgeological disasters in Guizhou Province, the main platform a map of Mainland disasterspatial data browsing,editing,query, statistics, subsystem management and maintenance.To achieve the rich geological disaster spatial data and attribute data integratedmanagement, enhanced by the integrated management of the relevant thematic dataContact enhance information management and use of geological disasters in GuizhouProvince. In this paper, the main tasks are as follows:(1) using and research some the ArcGIS10platform for all type of desktop APPs,spatial data engine SDE for Oracle10g,development and publishing platform ArcGISServer10. Deal with all kinds of spatial data sets through ArcSDE imported into theOracle database, the last corresponding spatial data services based on ArcGIS Serverrelease.(2) the use of desktop tools Oracle PLSQL and property forms part of thenon-spatial database in Microsoft Visual Studio2010development is called.(3) using ArcGIS Server10platform the ADF(Application Develope Framework)development model, design and implement a of Guizhou Province geological disasterscomprehensive two-dimensional subsystem development. Coding focuses on the theADF development mode, two types of Ajax-based partial refresh, property databaseback-end data services and map server platform invoke the background spatial data, remote sensing data slice services publishing and call platform for a variety of data calland management.(4) processing system deployment and publishing, as well as system maintenance,including error handling, parallel, the ArcSDE background maximum number ofconnections management.
