摘要
地理空间数据共享与互操作模式是数字地球的关键技术,是国家空间信息建设以及空间数据利用的前提。本文在分析了GIS数据集成、互操作以及GML研究现状的基础上,研究了GIS数据集成和互操作的系统框架;提出了基于GML空间数据交换和基于SVG的信息可视化模型。
Geography spatial data sharing and their interoperation model are the key technology of digital earth.They are also the precondition of national spatial information construction and spatial data utilization.Data integration and interoperation as well as GML present research status are discussed in this paper.The system framework of GIS data integration and interoperation is researched.The GML-based spatial data exchange model and SVG-based information visual model are proposed.
