摘要
本文首先结合GPS、RS、GIS技术的特点,分别阐述了它们在海岸带调查各个领域中的应用情况。即如何利用GPS实现岸线定位和剖面地形测量;如何利用RS技术实现海岸线提取、海岸带地表形态观察与分类、岸滩冲淤动态调查;以及如何建立海岸带空间数据模型,从而在GIS中实现海量空间数据的存储管理。接着根据3S技术的发展趋势,简述了3S集成技术,并初步探讨了其在海岸带调查中的应用。
According to the characters of the geographical information system （GIS）, remote sensing （RS）, and global positioning system （GPS）, firstly, the main application of GPS, RS, GIS in many fields of coastal zone survey is demonstrated, such as the application of GPS in coastline and beach-profile survey, that of the information of remote sensing images in coastline extraction, geomorphological mapping and the analysis of the evolution of scouring and silting in intertidal zone, and that of GIS in the accomplishment of geospatial database to store huge amounts of spatial data, which is on the basis of establishment of coastal geodatabase model. Finally, based on the developing tendency of 3S technique, 3S technique integration is introduced, and the application of that in coastal zone survey is discussed.
