Temporal smoothing


Temporal segmentation of the Landsat archive can also be used to "clean up" noise in sequential series of imagery, a process we call "LandTrendr temporal smoothing."   

The segmentation algorithms are run on a single index (in the figure below, on the NBR, or "normalized burn ratio").  The rules determined using that index for each pixel are then used to smooth the noise for that pixel in other spectral bands.
