海岸线提取技术研究进展
Advance of Coastline Extraction Technology
摘要
Abstract
Firstly, the problem of ambiguous coastline definition was discussed. Then based on the summary of field measuring mark line method and remote sensing extraction method to measure coastline, shortcomings of both methods that were inefficient, longer cycle and danger were pointed out. And then the mean methods and the reali-zation process of coastline extraction by LiDAR abroad were discussed, moreover supported by VDatum( Vertical Datum Transformation) in the USA, the coastline extraction by LiDAR was applied much widely, while at home the method study and ocean vertical datum construction were at starting stage. In the end several proposals for coastline extraction were put forward.关键词
