Research On The Hunan Forest Land Soil Testing And Formula Base Platform

Hunan forest land soil testing and formula base platform make full use of existing technology and infrastructure,based on the forest resource data management system,forest measurement formula for soil foundation data verification system,forest measurement formula for soil information query system provides the data,integrate all kinds of data,to realize the mountain land,forest resources,plant diseases and insect pests prevention and control,adaptive tree and scientific forestation,for all levels of forestry production,management and decision-making services provide basis for decision making.This paper deeply analyzes the key role of the geographic information system technology in Hunan forest land soil testing and formula base platform.The paper analyzes the status quo of GIS technology in forestry application from the aspects of forestry GIS characteristics,GIS spatial model and forestry GIS spatial index algorithm.By Forestry GIS as a whole research on and analysis of the specific measured in Hunan forestland soil testing platform on the application of key technologies,from the design and Realization of the platform of the important function launches the elaboration,the following three aspects is a platform to achieve the achievement of research and development is to solve the practical problems of key techniques,is of great significance to guide the practical production of forestry.(1)the data are highly integrated and shared,and the application system is seamless integration.In order to ensure the data accurate and consistent,the data of each subject system does not have a contradiction,must carry out data integration.The distribution system of the forest land is used to distribute the data of the forest,and the dynamic adjustment method is used to integrate the forestry special data.Each feature system does not repeat the production data,not only to maintain their own special data and share each other,to solve the problem of the data of the different forestry application system.(2)real time online update of forest spatial data.Users of the province's forestry sector at all levels through the network client on the graphics data online update.Selected need to update the class,through the elements of the tools for line segmentation,segmentation,merging operation,online editing graphic data,and stored in real-time to Shengting data center database.To ensure that the forest distribution and other important resource data centralized storage,centralized management,real-time update.(3)the rapid collection and update data in the field of the.Data acquisition and input of the PDA is carried out by the,and the information of the attribute information is updated by the acquisition results.Hunan forest land soil testing and formula base platform based on the advantages of PDA platform,the development of mobile clients,the efficiency of the work outside the industry to collect data greatly improve the level of accuracy has reached an unprecedented level.Hunan forest land soil testing and formula base platform based on the integrated use of Oracle and ArcSDE,ArcGIS based technology,co-ordinate the integration of forest resource data management system,forest measurement formula for soil foundation data verification system,forest measurement formula for soil information query system etc.,and ultimately achieve the data is highly integrated and fully shared,fast graphics collection,map quick rectification,the province's graphical online updates and other important goals.
