历史船舶流量及轨迹分析数据

基于历史船舶轨迹数据，查看区域范围内不同时间段的船舶轨迹，分析船舶流量的变化趋势和规律，为港口管理、航道规划、航线规划等提供参考依据。1.数据获取：通过我司船载AIS接收器和东海保障局合作获取实时和历史的AIS数据。
2.数据处理：对收集到的数据进行清洗和预处理。根据错误点监测规则、停留点监测规则以及冗余点检测规则，执行数据处理操作，包括去除重复数据和处理数据缺失，获取points轨迹数据。
3.轨迹数据可视化：AIS数据点的可视化，将所得的时间序列点在二维坐标进行标注，绘制船舶的轨迹散点图。轨迹散点图可直观展示船舶的行驶路径、运动趋势、分析散点的分布密度和分布区域为港口管理和航道规划等提供依据。

Based on historical ship trajectory data, this dataset enables viewing ship trajectories within a specified regional scope across different time periods, analyzing the changing trends and regular patterns of ship traffic flow, and providing reference bases for port management, waterway planning, route planning and other relevant applications.
1. Data Acquisition: Real-time and historical AIS data is acquired through the cooperation between our company's shipborne AIS receivers and the East China Sea Guarantee Bureau.
2. Data Processing: Clean and preprocess the collected data. Execute data processing operations in accordance with the error point monitoring rules, stay point monitoring rules and redundant point detection rules, including removing duplicate data and handling missing data, so as to obtain trajectory point data (referred to as "points" in this dataset).
3. Trajectory Data Visualization: Visualize the AIS data points, mark the obtained time-series points on a two-dimensional coordinate system, and draw the ship trajectory scatter plot. The trajectory scatter plot can intuitively display the ship's sailing path and movement trends, and support the analysis of the distribution density and distribution area of the scatter points, thereby providing a reliable basis for port management, waterway planning and other related work.
