摘要
分析了多源GIS数据融合现状,探讨了WebGIS中异构空间数据源的集成问题,提出了一个以XML和GML为统一的数据表示格式,以SVG形式交互显示矢量地图的WebGIS体系结构。该体系结构既充分利用了现有网络和数据资源,具有良好的可扩展性。
The present research on share of multi-sources GIS data is analyzed, the integration of heterogeneous spatial data sources in WebGIS is discussed, and then an XML-based WebGIS architecture is proposed, in which XML and GML are used as the uniform data presentation format and vector maps are displayed interactively in SVG. This architecture makes full use of the existing lnternet and data resources, and is well extensible.
