针对当前动态分段方法缺乏时间维的问题,在典型的标准动态分段基础上增加时间维线性特征,形成时空动态分段方法,并使用该方法在ArcGIS中对交通事件进行了可视化表达。
There appears to be a lack of temporal feature representation in classic dynamic segmentation.In order to meet the needs of representation of linear object with spatiotemporal feature,spatiotemporal dynamic segmentation method is proposed by adding temporal feature to classic dynamic segmentation.The author finally represents a traffic incident process by using spatiotemporal dynamic segmentation in ArcGIS.
