中文摘要: 为解决海量GIS地图信息显示分辨率高、处理难度大等问题, 研究了集群并行显示、WMS服务、GIS渲染显示等技术, 提出了以计算机集群并行计算为基础构建集群并行GIS拼接显示系统, 采用WMS并行获取GIS数据信息、地图投影变换处理数据、OpenGL并行纹理渲染, 进而实现GIS数据的超高分辨显示. 实验结果表明, 提出的集群并行GIS拼接显示系统可极大地提高地图显示分辨率、为海量GIS地图的超高分辨显示提供了可行的解决方案.
Abstract:To overcome difficulties in processing and implement the ultra-high resolution GIS map information display, technologies such as cluster parallel processing, WMS services, GIS rendering etc are researched in this paper. A cluster-based GIS tiled display system is presented. Parallel WMS access technology is used to get GIS data, projection transformation is discussed to process map data. And OpenGL texture rendering method is researched to parallel display. Thus, ultra-high resolution GIS data is displayed on the tiled screen. The experimental results show that the cluster-based GIS tiled display system presented is feasible and can greatly improve the display resolution of map.
