Since its appearance, the CoastSat toolbox has proven to be useful in research and management. Based on Python libraries for satellite image data acquisition and image classification, the software is capable of delinating shorelines. The original example included with CoastSat is for Narrabean beach (using file example.py and the folder examples)
This toolbox has been applied to the case of Tien Chau inlet, Vietnam. The initialisation steps are similar to that of CoastSat, but Python functions have been added to calculate the morphology of the coastline. Specifically, the length and the orientation of the sand spit are calculated based on the classified images.
The software tool can be run first from example_Tien_Chau.ipynb. Then, after the shorelines are delinated and their coordinates written to TienChau-analysis/*_mod.xyz, we can run calc_geom.ipynb to extract the sand-spit length and orientation (see the figure below).
