Google Earth Engine HWL Mapping Code

This is a custom Google Earth Engine code that uses a trained Random Forest classifier to classify wet and dry beach sediment, the boundary of which is a geomorphic proxy shoreline known as the high-water line. This code is written for PlanetScope imagery and will not work with other optical datasets as reflectance values will differ.

本数据集配套自定义的谷歌地球引擎（Google Earth Engine）代码，该代码采用经训练的随机森林分类器（Random Forest classifier）对海滩干湿沉积物进行分类，其分类边界为被视作地貌替代岸线的高潮线（high-water line）。本代码专为PlanetScope影像编写，无法适配其他光学数据集，原因在于不同数据集的反射率数值存在差异。
