When trying to regrid data from one spherical coordinate system to
another, I get the fullowing error:
This is my statement. I have used the same configuration with hundreds
of other problems,
it seems that I only get the problem with this specific combination of
coordinate system.
Where do I start?
qhull,ilon,ilat,inp_tr,sphere=sv,/delaunay
u2=griddata(ilon,ilat,u1,$
/sphere,/degrees,$
method='Linear',triangles=inp_tr,$
xout=tlon,yout=tlat)
This is the error message:
GRIDDATA: Value of Triangle index is out of allowed range.
Thanks
Axel

Hi,
Have you tried the same steps using TRIANGULATE instead of QHULL? It
might be worth a try. Alternatively, you could use GRID_INPUT to prepare
ilon and ilat.
