摘要
现有图例生成方法依靠人工编辑生成静态图例,无法根据地图视口内容的变化而动态改变,给图层丰富、样式复杂的地图交互带来了不便。针对上述问题,提出一种基于地图制图脚本的交互式动态图例生成方法,通过解析脚本,筛选内容、生成图例等步骤,根据地图视口内容自动生成图例。
Legend can't change its content as the user drags or scales the digital map. It may reduce the convenience of reading digital map with rich layers and complicated styles. To solve this problem, we proposed an automatic creating method of interactive legend based on cartographic script. After parsing the script and filtering the content, we are able to create a legend related with the content of the real-time map view automatically.
