摘要
近几十年来,海洋的重要性愈来愈明显,海洋地质调查作为获取海洋数据的重要手段逐渐受到关注。海洋数据与陆地数据相比,具有多样性和时空复杂性的特点。近年来遥感技术和地理信息系统技术发展迅速,遥感的实时性、大面积监测性的特点以及地理信息系统对空间数据的有序管理及支持辅助决策的功能为海洋地质调查开辟了新的前景。笔者结合遥感和地理信息系统的特点、发展趋势,介绍了其在海洋地质调查领域中的应用,并对其应用前景做出展望。
The importance of oceans has become more and more evident in the past several decades,and oceanographic survey that is an important method of marine data acquisition has attracted more attention.The variety and complexity of the marine dataset are improved compared with land dataset.Recently,remote sensing and geographical information system have opened up a new prospect for oceanographic survey with good temporal repetition,regional scale,spatial data management and auxiliary decision.Using integrated characteristics and development tendency of RS and GIS,this paper introduces their application to oceanographic survey,and predicts their prospect of development.
