CoastSat
A global shoreline mapping toolbox from publicly available satellite imagery.
A global shoreline mapping toolbox from publicly available satellite imagery.
聽is an open-source software toolkit that enables user to obtain time-series of shoreline position at any sandy coastline worldwide from ~38 years (and growing) of publicly available satellite imagery.聽聽
Satellite remote sensing currently offers medium-resolution (10 to 15 m) images at high temporal frequency (~5 days between images) and can provide low-cost shoreline data to coastal engineers, managers and scientists. This is often the only source of information on past shoreline changes at locations where no field measurements are available.聽聽
罢丑别听聽enables the non-expert user to extract shorelines from Landsat 5, Landsat 7, Landsat 8, Landsat 9 and Sentinel-2 images. The shoreline detection algorithm implemented in CoastSat combines a sub-pixel border segmentation and an image classification component, which refines the segmentation into four distinct categories such that the shoreline detection is specific to the sand/water interface. The horizontal accuracy of the time-series of shoreline position is ~10 m. More details can be found in "".
罢丑别听聽provides an interactive platform to access satellite-derived shorelines obtained with CoastSat at beaches around the Pacific Rim, including Australia, California, Mexico and Hawaii.聽
A couple of examples are shown below for Stockton Beach in NSW and the Tweed River Entrance bypassing system:聽
