The Study of Coastline Extraction and Validation Using ETM Remote Sensing Image
基于ETM遥感影像的海岸线提取与验证研究

Using the ETM remote sensing image and two kinds of methods—Soble arithmetic which is one of the edge detection methods and MNDWI,there is going to research the coastline extraction in Yellow River delta which has artificial coastline and muddy coastline,then validate and evaluate the coastline extractions.The result indicates that the Soble arithmetic is more accurate.This is especially obvious in the muddy coastline,and we can find that the relative error has reduced to 0.018% from 0.025%.
