Abstract

Tidal flat area gains abundant natural resources. With the development of the coastal economy, tidal flat area possesses an unstable nature, thus of significant value for its study. Waterline extracting methods are essential to understand the dynamic change of tidal flat. In order to find a good method, we took Rudong County in Jiangsu Province as the research area, by using the HJ1A/1B images, waterlines are generated under the method of visual interpretation extraction, Canny edge detection, threshold segmentation and object-oriented classification. By contrast, the paper considered object-oriented classification as an effective method to extract waterlines.
