Abstract

This paper presents an effective and accurate approach to extract coastlines from InSAR coherence map. The key technique is to automated extract the island coastline quickly in investigating the changes of the island coastlines using remote sensing technique. According to the tremendous difference of backscatter in InSAR coherence map between in sea region and in land region, an automated extracting method based on InSAR coherence map is proposed in this paper. Firstly, it generates the interferogram and coherence map based on InSAR technique and SAR complex data. Then it gets the information of coastlines through threshold segmentation and edge detection for the coherence map. At last, we choose the ERS-1/2 SAR data to carry out the coastline extraction test. The test proves that it is an effective and accurate approach to extract coastlines from InSAR coherence map.
