There is another method that does not use the Programmable filter.
In that way, the use of nearest neighbor extrapolation, using the Voroni kernel of the Point Interpolation filter, extends the value at ymax to the entire region.
The steps are as follows:
-
Use the
Plot Over Linefilter to plot the data on a line parallel to the horizontal axis at ymax.
-
Using the Voronoi Kernel of the
Point Dataset Interpolatorfilter, the ymax data is extrapolated to the nearest neighbor over the region. Here, specify the following:
-
Input:
PlotOverLine1 -
Source:
Slice1 -
Kernel:
VoronoiKernel
-
Select both
Slice1andPointDataSetInterPolator1on the Pipepline Browser while holding down the Ctrl key, and merge the data with theAppend Attributesfilter. -
Finally, the
p - hydroPrescould be calculated using theCalculatorfilter.
