【摘要】 随着世界经济的发展 ,海上交通越来越繁忙 ,也越来越重要了。海上交通数据的海量性、实时性、多态性和分布性这些特征使得我们很难处理它们。Internet和分布式计算的发展使处理海量的、分布的海上交通数据成为可能而且容易。大部分海上交通数据具有时间 空间特性 ,所以GIS和交通技术的结合是复杂海上交通的有力解决方案。为此 ,研究了如何构建分布式的GIS OT更多还原

【Abstract】 With the development of world economy, ocean transportation is becoming heavier and more important than before. Its data’s mass, real time, multiple and distributed features make it very difficult to deal with them. The development of Internet and Distributed Computing make it possible and convenient to process mass and distributed ocean transportation data. Most of ocean transportation data are spatial temporal in nature, so integration of GIS and transportation technology is the powerful solution to resolve sophisticated ocean transportation. This paper researches into how to build the distributed GIS OT.更多还原
