基于COM的GIS海量影像数据管理系统

GIS Huge Image Data Management System Based on COM

目前地理信息系统大多是基于相互独立和封闭的平台的开发,不同的数据格式和操作使系统间的数据交换和共享的实现十分困难 ,并阻碍了地理信息系统的发展。COM技术的采用正好解决了这一问题,它可以将数据和操作集成起来,实现系统的无缝集成。随着地理信息系统的发展,遥感影像数据的使用越来越广泛,由于它的数据量大、数据类型多等原因,需要建立一个海量影像数据管理系统才能满足应用要求。 针对这种情况,该文提出了基于COM的GIS海量影像数据管理解决方案,并给出了应用实例。

Current GIS is mostly based on the close development platform of reciprocal independence, whose different data format and operation not only causes the realization of exchanging and sharing of the data much difficulty, but also blocks the development of GIS. However, the application of COM technology could fitly settle that problem, and its integration of the data and operation can realize the seamless integration of system. With development of GIS, the employing of the image data is more and more widely, but because of the image datas tremendousness and various formats, a huge image management system should be founded to adapt to it. As for that situation, this paper brings forward a solvable project that called GIS huge image data management system based on COM, and presents one instance.
