I have some sparse data (FWHM values) which I am sending into plgriddata, in this case using GRID_NNLI, 1.001f. When I look at the values in the data versus the output grid, I see:
I've tried various nn.... algorithms, but none appear to preserve the actual minima and maxima. Is that to be expected. I had rather hoped that the actual data points that I do have would be (close to) preserved.
Guidance will be much appreciated.
