CCD-Plugin
Plot a Landsat or Sentinel-2 time series at any coordinate and find its trends and breakpoints of change with the CCDC algorithm
Pick a coordinate and the plugin pulls every clear Landsat (4, 5, 7, 8 and 9, Collection 2) or Sentinel-2 observation for that pixel out of Google Earth Engine, then runs the Continuous Change Detection (CCDC) algorithm over the series. CCDC fits a harmonic model to each stable period and reports a break only where several consecutive observations stop agreeing with it, so the plot shows the observations, one fitted curve per segment, and the dates the pixel changed. Bands and spectral indices, cloud masking, the seasonal window and the CCDC parameters are all configurable. Requires an active Google Earth Engine account and the Google Earth Engine plugin.
