LandTrendr processing occurs in a series of steps shown below.
|The schematic above outlines the overall workflow of LandTrendr. Images must be acquired and "cleaned" before temporal segmentation occurs, resulting in a "Landsat data stack". Temporal segmentation distills each pixel's history into straightline segments. The primary product of segmentation is a set of files (vertex files) that compactly capture the endpoints of those straightline segments. These can then be queried to make maps of change, or they can be used to temporally-smooth other bands of the same image. Temporally-smoothed images can then be used to build yearly maps of land cover.
