| 摘 要： | 在对SVG和WebGIS等技术研究的基础上，结合实际应用的需求，提出了一种基于SVG的分布式轻型WebGIS框架模型，设计了主地图与鹰眼图之间图层的映射模型及运行体系，实现了主地图与鹰眼图正向同步与反向同步视图控制算法和分布式动态地图加载算法，并对其进行了详细的阐述和论证，其已经成功地在大庆油田得到了应用。

| Abstract: | Based on the research of WebGIS, SVG and related technologies, combined with practical requirements, a distributed light WebGIS framework based on SVG is proposed; the relationship between main map and eagle eye map and the running architecture is designed, and a kind of forward and back synchronous algorithm between main map and eagle-eye map and a kind of distributed dynamic loading algorithm of map are realized. At present, a light WebGIS platform based on these technologies has successfully been applied to Daqing Oil Field, the bigaest oil field in China. |
