  1. A lot of data of elevation in different places of the shallow water of n antong were obtained by fish - exploring machine and gps determining and tide cor recting. an image which reflects landforms of nantong was obtained by selecting f rom the many noaa images on different channels and in different phases. based on the image, grey scales corresponding to different places were obtained. by using c la ssifying liner regression technique, liner regression equations were established between the elevation and grey scale, and the threshold values of grey scales of the different elevations were determined. according to the threshold values, the a reas of the tidal zone above different elevations of the shallow water of nanton g were estimated

    通過利用gps及漁探器實測，並進行潮位訂正，獲得南通淺海海域大量測點的高程資料；通過對多時相各通道noaa衛星照片進行篩選，挑選能反映淺海地貌的通道資料，從中讀取各測點相對應的灰度值，在此基礎上利用分級線性回歸，建立不同高程范圍內的高程、灰度線性回歸方程，確定不同高程的灰度閾值，從而測量出南通市淺海海域不同高程以上的潮間帶面積、分佈。
