【摘要】 针对网约车轨迹数据,设计和实现了基于Web的轨迹数据可视化系统。首先介绍了系统的整体框架,采用B/S架构,基于MVC模式,结合ECharts组件实现轨迹数据的可视化。然后从数据清洗、数据格式转换、数据压缩等方面描述了系统对原始数据的预处理工作。最后分别概述了直接可视化、聚集可视化和特征提取可视化的实现方法及结果分析。更多还原

【Abstract】 Based on the taxi trajectory data, a web-based trajectory data visualization system was designed and implemented. Firstly, the overall framework of the system was introduced. The B/S structure was used to realize the visualization of the trajectory data based on the MVC pattern and the ECharts component. Then, the preprocessing of the original data was described from the aspects of data cleaning, data format conversion, and data compression. Finally, the implementation methods and results analysis of direct depiction, summarization and pattern extraction are summarized.更多还原
