全球船舶历史船位查询数据

查询全球任一船舶3年内的历史轨迹数据，结合海图显示，包括列表和船舶轨迹。岸端管理人员可以了解所管理的船舶的历史动向，也可帮助用户了解关注的船舶的历史动向1、数据收集：收集全球船舶的动态数据，包括船舶的位置、速度、航向、时间等信息。数据来自于船舶自动识别系统(AIS)及卫星报位设备。
2、数据预处理：岸端服务器对收集到的数据进行清洗和预处理，包括去除重复数据、处理数据缺失、转换数据格式等。
3、轨迹提取：从预处理后的数据中提取船舶的轨迹。使用基于时间的方法：根据船舶的时间戳信息，将其位置信息连接起来，形成船舶的轨迹。
4、轨迹抽稀：对提取出的船舶轨迹进行分析，根据海图比例大小，保留拐点等关键点，对船舶轨迹进行抽稀筛选。
5、结果可视化：将分析结果在海图上进行可视化展示，包括船舶的轨迹图、航行指标图、航线图等。

Query the historical trajectory data of any global ship within the past 3 years, and display it in conjunction with nautical charts, including ship lists and vessel trajectories. Shore-based managers can gain insights into the historical movements of the ships under their jurisdiction, and also assist users in understanding the historical trends of the ships they are interested in.
1. Data Collection: Collect dynamic data of global ships, including vessel position, speed, course, timestamp and other related information. The data is sourced from the Automatic Identification System (AIS) and satellite positioning reporting equipment.
2. Data Preprocessing: The shore-based server performs cleaning and preprocessing on the collected data, including removing duplicate data, handling missing data, and converting data formats.
3. Trajectory Extraction: Extract vessel trajectories from the preprocessed data. A time-based method is employed: connect the position information sequentially based on the ship's timestamp to form the complete trajectory of the vessel.
4. Trajectory Simplification: Analyze the extracted vessel trajectories, retain key points such as turning points according to the scale of the target nautical chart, and conduct thinning and screening on the trajectories.
5. Result Visualization: Visually present the analysis results on nautical charts, including vessel trajectory maps, navigation indicator charts, route maps, and other relevant visualizations.
