Abstract

Land subsidence is a persistent and continuous surface motion downward relative to an elevation datum. Monitoring the subsidence to prevent land crises, such as floods and salted land, in advance is an important subject. A conventional method to monitor land subsidence is based on measurement of level net. However, the method is ineffective and uneconomical to monitor large land in a long time, and only a few historical data are available to support this work. In this paper, we propose an idea of using the past DEMs data generated at different periods to retrieve the history of land subsidence. The study area is in the Yunlin county of Taiwan. By analyzing the differences among the multitemporal DEMs, the experimental results show that the proposed method is feasible to provide historical information of land subsidence in Yunlin.
