摘　　要：为解决海量遥感影像数据的快速浏览、显示问题,基于ArcEngine开发模块,应用海量数据的组织与管理技术,开发嵌入式GIS应用系统——地理信息产品综合浏览系统。通过对影像数据和DEM分层分块建立多分辨金字塔模型组织数据,利用几何纠正、重采样等整合数据,控制实时调入的数据量,实现了海量数据实时浏览,查询,DOM与DEM、DLG数据的叠加与三维可视化等主要功能,具有显著的理论价值及社会应用前景。For a rapid browse and display of mass remote sensing data, a GIS system for integrated browsing, which is an embedded GIS System, has been developed based on ArcEngine Module and using the technology of mass data organization and management. In order to control the amount of transferred data in real time, some measures must be taken. For instance, a multi-resolution pyramid model data is built based on the image and DEM block. The data are integrated by the geometric correction and resampling. Therefore, the real-time mass data browsing, querying, the overlaying of DOM, DEM and DLC~ and three-dimensional data visualization are achieved. The study is of significance to the theoretical study and applications.
