Another cry for help! I'm a regular user of IDL and am using it to process
RS data.
I have some large regular arrays that have holes in and have tried to
interpolate across them but I get either bad results or the process is too
slow! TRI_SURF is fastest but gives horrible striping effects with large
variations across larger holes - this is also the case for TRIGRID. The
best by far is MIN_CURVE_SURF (KRIG2D is really slow) but this tends to slow
down my program to the extent that it takes 3x longer to complete than with
TRI_SURF or TRI_GRID!!!
The call I'm using is:
result=min_curve_surf(z,x,y,gs=[1,1],bounds=[0,0,xdim0,ydim0 ])
Z, X and Y contain the value and ordinates of the good (regularly spaced)
pixels within the BOUNDS box.
Any suggestions/alternatives would be much appreciated.
Thanks in advance
Andy
