土地资源遥感监测信息服务系统关键技术研究

Key Techniques of Land RS Monitoring Information Service System

本文从土地遥感监测信息的特点入手,研究了土地遥感监测信息服务系统的构建技术。在后台数据组织方面,针对土地遥感监测信息包含多种类型和相互关联的数据源,提出了基于元数据机制的遥感监测信息组织体系;在应用部署上,通过空间数据库引擎和地图网络服务引擎实现后台对空间数据的调用和处理;在客户端功能开发上,实现了基于WebGIS的土地遥感监测信息综合应用与服务。

The land remote sensing （RS） information contains many kinds of associated data. In its application, especially in the internet web services, some handicaps are not easily overcome. For example, the land RS information is difficult to be organized and extracted efficiently. With higher resolution RS data applied in the land monitoring, more difficulties come forth in the information sharing and services. Aiming at the information sharing and services, this paper has studied the characteristics of the land RS information and constructed the architecture of the Land RS Information Sharing and Service System. In the information organization, a metadata mechanism is set up for data storage and management in the background. In the application deployment, the spatial data engine and internet map service platform are used for the spatial data transfer and disposal. In the client function development, some information sharing and services functions are applied based on the metadata mechanism.
