Heterogeneous Integrated Dataset for Maritime Intelligence, Surveillance, and Reconnaissance

Facing an increasing amount of movements at sea and daily impacts on ships, crew and our global ecosystem, many research centers, international organizations, industrials have favored and developed sensors, detection techniques for the monitoring, analysis and visualization of sea movements. Automatic Identification System (AIS) is one of these electronic systems that enable ships to broadcast their dynamic (position, speed, destination...) and static (name, type, international identifier…) information via radio communications. Having spatially and temporally aligned maritime dataset relying not only on ships' positions but also on a variety of complementary data sources is of great interest for the understanding of maritime activities and their impact on the environment. This dataset contains ships' information collected though the Automatic Identification System, integrated with a set of complementary data having spatial and temporal dimensions aligned. The dataset contains four categories of data: Navigation data, vessel-oriented data, geographic data, and environmental data. It covers a time span of six months, from October 1st, 2015 to March 31st, 2016 and provides ships positions within Celtic sea, the Channel and Bay of Biscay (France). The dataset is proposed with predefined integration and querying principles for relational databases. These rely on the widespread and free relational database management system PostgreSQL, with the adjunction of the PostGIS extension, for the treatment of all spatial features proposed in the dataset.

面对日益频发的海上船舶活动及其对船舶、船员与全球海洋生态系统造成的日常影响，众多科研机构、国际组织与工业界已研发并推广了用于监测、分析与可视化海上活动的传感器及探测技术。船舶自动识别系统（Automatic Identification System，AIS）正是这类电子系统之一，它可通过无线电通信实现船舶动态信息（位置、航速、目的地等）与静态信息（船名、船舶类型、国际识别码等）的播发。
构建兼具空间与时间对齐特性的海事数据集——此类数据集不仅依托船舶位置数据，还整合了多种补充数据源——对于深入理解海上活动及其对环境的影响具有重要学术与应用价值。本数据集包含通过船舶自动识别系统采集的船舶信息，并整合了一组具备空间与时间对齐维度的补充数据。
该数据集涵盖四类数据：航行数据、面向船舶的数据、地理数据与环境数据。数据集的时间跨度为6个月，即2015年10月1日至2016年3月31日，涵盖凯尔特海、英吉利海峡以及法国比斯开湾海域内的船舶位置数据。
本数据集附带面向关系型数据库的预定义集成与查询规则，该规则依托当前广泛使用的开源免费关系型数据库管理系统PostgreSQL，并搭配PostGIS扩展插件，以处理数据集中所有的空间特征信息。
