The Research Of Recommended Fertilization In XiChang Based On WebGIS

WebGIS namely web geographic information system, it is Internet technology and GIS, the combination of the geographical data and GIS function to the network service (WebService) ways in which various issued on the network platform users through ordinary browsers can use geographic data and map service. With the deepening of Internet influence, the widespread application of GIS technology, people have already can't satisfy traditional WebGIS performance effect and interactivity of system development, and the simplicity and system scalability also eliminating higher requirements. Set B/S and C/S in the integration of RIA (single apply, Rich Internet Internet Application system) was born, it brought in to Internet Application of revolutionary change WebGIS can also give a lot of new development opportunities. Silverlight is the current development of the technology of mainstream RIA. This paper based on the above technology, combined with REST style architecture to distribute network geographic information service to simplify the process of user obtaining operating resources, completing the feedingstuff industry.xichang became WebGIS system of soil fertilizer.Establish feedingstuff industry.xichang became WebGIS system, soil fertilizer fertilization work not only solves the comprehensive management difficult to attribute data transmission, formula problems such as universal difficult scheme, while improving the fertilization level and production efficiency. To accelerate traditional agriculture to modern information agriculture transition, promote the progress of cultivated land nutrient management technology, which is of great realistic meaning and broad application prospects, the concrete content includes:(1) establish the feedingstuff industry.xichang became soil testing system spatial database fertilizer.Analyzed the department of agriculture "soil testing and fertilizer technical specifications (try out)", combined with the rice, the department of agriculture will provide feedingstuff industry.xichang became corn and wheat formula, according to the database design standard scheme, scientific and reasonable designed and built attribute database. Combined with the digital 1:50,000 feedingstuff industry.xichang became after 1:50,000 soil chart and administrative city zoning, using third-party CASE tool construction project data, eventually converting UML model, spatial database for the feedingstuff industry.xichang became the construction of WebGIS system fertilizer laid a data base.(2) through the normal sexual distribution examination and Kringing interpolation technology to soil sampling data points feedingstuff industry.xichang became, and combining the analysis and inspection of the department of agriculture will provide feedingstuff industry.xichang became soil testing and formula scheme, made feedingstuff industry.xichang became wheat, corn and rice formula thematic maps, trace element content diagram, completed the xichang soil fertilizers FangChengTu project. Finally the ArcGIS Server 10 will project data for map service, use released REST style system structure simplified WebGIS system development resources orientation, reduces the time and economic investment.(3) established the feedingstuff industry.xichang became WebGIS system fertilizer.Research for the feedingstuff industry.xichang became based on fertilizer model, adopt Microsoft had Blend development design client, ArcGIS Server 10 release ArcSDE for map services, Microsoft SQL Server Express for spatial data engine,2008 REST the API to realize by client and ArcGIS Server Web service interaction, and reasonable use caching technology promotion data access efficiency, finally established the feedingstuff industry.xichang became WebGIS system, fertilizer reached effective promotion experiment results, promote the progress of cultivated land nutrient management technology, fertilizer soil testing and feedingstuff industry.xichang became the decision-making and implementation project to provide support, accelerate the traditional agriculture to modern agricultural transition effects, and also verify the REST of Silverlight and based on WebGIS has wide application prospects.
