A Study of Shoreline Changes in Antarctica (Terra Nova Bay) Based on SAR Data

Cho, J.H., Cho, J.M., Yun, H.S., Kim, T.W., Kim, C.W., 2013. A Study of Shoreline Changes in Antarctica (Terra Nova Bay) Based on SAR Data Unlike optical imaging, Synthetic Aperture Radar imaging can produce images regardless of the weather and the time of day, which makes it a useful tool for collecting topographical data in tropical rainforests and in the North and South Poles, where traditional optical imaging is ineffective due to the rapidly changing weather. For this study, this researcher acquired SAR imagery of Terra Nova Bay, located near the South Pole, from October 8, 2011 to March 11, 2012 to observe the changes in its shoreline in summer. SAR imagery was captured once every 11th day to determine the exact time in summer when the glaciers and ice along the shore melt. The acquired stereo SAR imagery data were then processed by applying the radargrammetric method along the shoreline to reduce the speckles specific to the SAR data, and to ensure the accuracy of the coordinates and the s...
