Remote sensing monitoring of coastline change in Pearl River estuary

摘要

The study focused on applying remote sensing technology to monitor the rapid varying of coastal lines on Pearl River delta, Hong Kong and Macau. Which are pretty difficult to be measured timely and quantitatively. The "Neural Network classifier" is used upon multi-temporal remote sensing images to classify the changes of coastline in different periods. Digital coastline is overlay with the remote sensing image to show and verify the location of true shorelines. Land reclamation and new airports, together with their related constructions, in Hong Kong and Macau are the most important factors.
