Interpolates a time series using a set of LandTrendr breakpoint years. For each input band in the timeSeries, outputs a new 1D array-valued band containing the input values interpolated between the breakpoint times identified by the vertices image. See the LandTrendr Algorithm for more details.
| Usage | Returns | ee.Algorithms.TemporalSegmentation.LandTrendrFit(timeSeries, vertices, spikeThreshold, minObservationsNeeded) | Image |
| Argument | Type | Details | timeSeries | ImageCollection | Time series to interpolate. |
vertices | Image | Vertices image. A 1D array of LandTrendr breakpoint years. |
spikeThreshold | Float, default: 0.9 | Threshold for dampening input spikes (1.0 means no dampening). |
minObservationsNeeded | Integer, default: 6 | Min observations needed. |
