The Snow Disaster Monitoring And Early Warning System In Pastoral Area Of Qinghai Province Based On MATLAB And Java

There is another usage of spatial data is to build a GIS system to achieve target function.In a way,building and using WebGIS is more convenient for users to use spatial data by connecting to different network terminals,and it is easier to handle these data.Although there are a lot of models about snow disaster monitoring and early warning,and scholars have constructed many WebGIS in different areas.There are some problems such as insufficient application of the research model,simple system function,and low system reuse and so on.Therefore,it is necessary to build a better system basing on these models.We can use these models to guide the producing activity,improve the data calculation ability of Web system,and reduce manual handling.In this study,we attempted to use MATLAB to realize the Logistic linear regression model of snow disaster risk estimation and the BP-ANN model of livestock mortality estimation in a snow disaster monitoring system based on J2 EE,Goserver,Openlayers,PostgreSQL and other technologies to achieve the implementation of browsing,importing,exporting,information maintenance and the multiparameter operation of raster data,and summarized the process of instantiating a research model as an integrated module,and the way of storage for raster data.This paper will also describe the specific process of this research such as the status of WebGIS application of snow disaster monitoring and early warning,the research ideas,methods and techniques,the overall design of system,the detailed design of each module,the design of database,the integration of the research model,the storage of raster data,the inadequacy of topology structure,and the design of system structure,storage and code.The raster data online calculation has been realized by MATLAB and Java,which the monitoring model of snow disaster was applied in WebGIS,and the result of application is satisfying.This research contained a complete process of system design and development,and basically actualized the main functions of the initial design of system.
