基于Geotools的矢量数据自适应渲染技术研究

Research on the Adaptive Rendering Technology of Vector Data Based on Geotools

随着WebGIS技术在各行业的快速应用,针对矢量数据在前端地图表达和服务发布过程中效率较低的问题,借助Geotools类库以及风格化图层描述语言,通过矢量数据的读取与属性解析,基于标准样式库的自适应匹配、风格化图层描述文件生成与动态渲染等过程,实现了地图图层的自适应匹配渲染和个性化配图,从而大幅度提高了地图配图与渲染的效率,可为矢量数据快速渲染和可视化表达提供新的技术手段。

The WebGIS technology have been rapidly used in all kinds of fields and is still in the development stage,aiming at the low efficiency of vector data in the process of front-end map expression and service publishing,with the help of Geotools class library and stylized layer description language,through the vector data reading and attribute analysis,adaptive matching based on standard style library,stylized layer description file generation and dynamic rendering,the paper achieved that adaptive matching rendering and personalized map matching of map layers,which greatly improves the efficiency of map matching and rendering,and provided a new technical means for rapid rendering and visualization of vector data.
