LandTrendr

LandTrendr is set of spectral-temporal segmentation algorithms that are useful for change detection in a time series of moderate resolution satellite imagery (primarily Landsat) and for generating trajectory-based spectral time series data largely absent of inter-annual signal noise. The LandTrendr algorithm has been used for analysis of change in Landsat spectral time series data. Here, we review LandTrendr for the Google Earth Engine (GEE) platform.
