基于点与热度的交通时空数据可视化

摘要

针对现有交通时空数据可视化交互解决方案,在可视分析交通时空数据时无法兼顾通用性和专业性的问题,设计并实现了交通时空数据可视化平台.通过统一的数据表示方法,实现对数据的导入、处理及可视化展示,完成基于交互的任务逻辑设计,实现在兼顾通用性的同时对时空数据提供多样化可视化的分析手段.%According to the problem that the existing interactive data visualization solutions can not take into account generality and speciality in the visual analysis of traffic spatio-temporal data,a visualization platform for traffic spatio-temporal data is designed and implemented.Based on the unified data representation method,the functions are realized as follows:data import,data conversion and visual representation.The design of visualization task logic based on interactive is also completed.The platform improves the versatility and at the same time provides a variety of visualization methods for spatio-temporal data analysis.
