Enhancing maritime domain awareness and threat detection through space-time knowledge extraction of novel geographic information sources

麦德龙系统有限公司(MDA)是通信技术领域的全球领先企业，也是加拿大地理空间行业的先驱。基于卫星的数据现在能够近乎实时地描述所有船只在海上的位置。因此，MDA正在开发增强的海上监视能力，以支持对非法捕鱼、海盗和污染等邪恶海上活动的侦查。对海洋环境进行真正的业务监视需要更多的信息，而不仅仅是船舶位置，如关于海事公司、港口记录、天气、船只特征和环境数据的信息。我们的目标是开发一种方法，将特别地理空间信息纳入到MDA现有的和不断发展的海洋领域感知系统中。为了实现这一目标，我们将1)根据网络信息源的初始列表建立相关信息源的数据库，2)从这些信息源中提取地理和属性信息，并将这些信息与船舶位置数据融合，3)开发集成和排序框架，以支持对新信息源的价值评估，4)提供地图模型输出和基于网络的地图界面，以探索空间综合的海洋监视数据。

MDA Systems Ltd. (MDA) is a global leader in communications technology and a pioneer of the Canadian geospatial industry. Satellite-based data are now able to describe the location of all ships at sea in near-real time. As such, MDA is developing enhanced maritime surveillance capacity to support detection of nefarious maritime activities such as illegal fishing, piracy, and pollution. True operational surveillance of the maritime environment requires more information than just ship location, such as information about maritime companies, port records, weather, vessel characteristics and environmental data. Our goal is to develop a methodology for incorporating ad-hoc geospatial information into MDA's existing and evolving maritime domain awareness system. To meet this goal, we will 1) develop a database of relevant information sources based on the initial list of web sources, 2) extract geographic and attribute information from these sources and fuse this information with ship location data, 3) develop an integration and ranking framework to support evaluation of the value of new information sources and 4) provide mapped model outputs and a web-based map interface for exploring spatially integrated maritime surveillance data.
