Abstract

In order to study the impact that land reclamation had on coastline of Fujian Province, three phases of Landsat TM/ETM+ image, spanning 15 years, were used to monitor the coastline change. The entire coastline was extracted from preprocessed Landsat TM/ETM+ images based on edge detection operator-Canny. We also improved the computational efficiency of image analysis by developing an image blocking algorithm with the IDL embedded in ENVI software. The length of the coastline for each imagewas calculated through the spatial calculation function of GIS platform, which shows that the length of Fujian coastline ranges from 3167.4km to 3218.2km, and to 3304.7km. Our results also indicate that the land reclamation in Fujian Province has caused the coastal lineto become shorter year by year.
