Preliminary code associated with Geophysical Research Letters article, The Color of Rivers (10.1029/2020GL088946). This code extracts Landsat surface reflectance and attaches it to river centerlines.

We introduce a new approach to depth and reflectivity estimation that emphasizes the unmixing of contributions from signal and noise sources. At each pixel in an image, short-duration range gates are adaptively determined and applied to remove detections likely to be du...
