摘要
采用空间数据库技术、Web技术、系统开发语言(JAVA语言)、Visual C++语言、遥感技术与WebGIS技术相结合的技术解决方案和方法,以空间信息的完全共享为出发点,从用户的需求、空间数据的特点和信息服务等3个紧密联系的层面及其相关的技术支撑方面,探索WebGIS环境下草地资源空间数据的共享、分析及其专题应用,可以为各种Web用户提供方便、有效的图文查询,使其便捷地访问分布式的异构空间数据库,并为各终端用户提供均质、集成和无缝链接的时空数据服务。预研究表明,运用上述技术组合构建草地生态系统的虚拟多维空间的方案切实可行,能够为业界提供一个方便、快捷的信息查询和空间分析共享平台,对实现我国数字草地具有重要意义。
By using the solutions that combines the database technology, Web technology, Java Language, Visual C+ + Language, Remote Sensing with WebGIS technology according to information sharing absolutely, to explore the grassland resources sharing, analyzing and map application in the environment of WebGIS considering the need of clients, the characteristics of grassland resources and the information serving, etc. the system can provide convenient and effective map-text inquiry , and the mean, integrated and seamless interlinked serves for the Internet clients to visit the distributed isomerous spatial database con- veniently. The result of the studies showed that it is reasonable that the virtual multidimensional space of grassland ecosystem is constructed by using of the above technical combination. Consequently, a sharing platform will be provided for the grassland industry by the system which can be inquired conveniently and analyzed concisely, and it will be most significant for China to construct the digital grassland.
