Based On Google Earth Liaoning Province Climate Resource Information Query System Design And Implementation

Our country has much more Natural resources than other countries, particularly the Climate resources. It's concerns the Major issues that our country's social and national economy developing sustainable. It's found that the development of technology our country's climate resources need to further improve throughinvestigate and study.The study of the climate resources information system gradually become key factor for exploit the climate resource development in our country. Climate resources information system is a expert information system.GIS as a High-tech as a set of datebase, space topology information, and the computer graphics, storage and processing space information, has already became the technical support for the expert information system.Google Earth(GE) use of the technology of WebGIS B/S frame structure, according to geography places provide various kinds of RS image date make use of Internet. Make GE lead into the query system of Liaoning climate information. Based on GE platform, Combined with the professional knowledge of climate resource field, realize the professional system of function of query climate resource information. Through provide the RS images of GE full use data, shows climate resource related information more image, improved the efficiency of greatly. Also has certain reference value For climate resource information performance method innovation.System access GE through the client local server , The user acquire RS image data through GE, deposit system user management database. Deployment database on the local server, deployment GE software and client program on the client. In order to keep system combined with GE official server, the system not only connected with local server but also keep connected with world wide web.According to the analysis for requirements and the function of system, system mainly realizes four function modules:Maps browse module: call the COMAPI make the system to achieve the GE browse and search operation, and obtain the RS Image data which users needs, It's the basis function module for system implementing.Data conversion module: shows fundamental geographic information At GE earth area, And realized the function of SHP conversion to KML format in the system. Climate resource information query module: Realize the function of integration and inquires for climate resource information.Climate resource information analysis module: realize the function of statistical analysis for climate resource information.The paper make prospect for the after work, combinated the model of climate resource with geographic information system. Provide a better platform on inquires the climate resource information for the following the public persons, scientific research workers and managers, and has certain practical value.
