| The National 973 Plans Chinese Land Ecology Carbon Collects/Source Short-term Evolution and Forecast Database,which content and result are very important, In the research process need lots of image data to research, analysis and display.But because of the mass of data there are problems of inconvenient to find, Limited of storage and difficulty of sharing. Serious block on the study.To solve of these problems,one great choice is with the help of computer.Use computer to build image database,it could supply faster and accurate search,avoid the problem of not enough storage space of personal computer,and sharing the data by network.It would help to use the image, improve the efficiency.This study combine the image database,GIS and network,build the resources and the environment data network service system,the datas save in the servers,share and used by the network, to achieve the GIS on the network,so that the user no need save the data in his own computer when he use it,search the data easily,and ues the GIS function.The article first analyze the advantage of WebGIS,bring up a plan which is reasonable and workable,and introduced the detailed process of the database.Finally, test and verify the resources and the environment data network service system, Through practical application, achieved good results,is a successful exploration of Computer technology involved in research work. The main achievements of this thesis are as follows:1. Investigate an actual issue,work out the technique of demand.2. The first time combine the GIS,WEB and environmental Studies, solved the problem of how to use computer technology in the process of environmental Studies.3. Analyzed the Massive Data's storage and load, and point out the Solutions of the increasing of the data in the further. 4. Studied the technology of WebGIS, designed the framework of the resources and the environment data network service system. 5. Built resources and the environment data network service system based on ArcIMS. |
