This toolbox uses the Google Earth Engine Python API to explore collections of publicly available satellite imagery (Landsat, Sentinel). It has .py routines to: - read and preprocess satellite images (cloud masking, contrast stretching) - pansharpen Landsat 8 images - extract shorelines with the Marching Squares algorithm - classify image in 4 classes (sand, whitewater, water, other) using a Neural Network classifier Requirements: all the packages contained in py3_environments.txt
