---|---|
Transformation Group: |
Interpolation Serial |
Description: |
Fills gaps in a time series that contains direction data values (e.g. wind direction in degrees), using linear interpolation. The direction values are interpolated over the smallest angle. For example halfway between directions 0 degrees and 350 degrees the interpolated value would be 355 degrees. For a gap between two directions that are exactly opposite (e.g. 90 and 270 degrees) the interpolated values will be equal to the last known direction. |

Background and Exceptions: |
The direction values are interpolated over the smallest angle. For example halfway between directions 0 degrees and 350 degrees the interpolated value would be 355 degrees. |
Input
todo
Options
todo
maxGapLength
Optional maximum length of gap in number of time steps. Gaps equal to or smaller than maxGapLength will be filled with interpolated values. Gaps larger than maxGapLength will not be filled. If maxGapLength is not defined, then all gaps will be filled with interpolated values.
