Dear Ferreters,
I have an ice field that is a matrix filled by 0 or 1. Because of weak resolution I need it to be interpolated on a finer grid.
I tried out two approaches.
The first, I interpolated with using @SBX and @SHN functions. Basically, I got neat result except to the boundary where I got a lack of data. Because this functions don't have data to interpolate and ending up with 0 value.
As the second I used scat2gridgauss_xy function which gave me smoother result but near the boundary I got the ice that should not to be. I think that this function is do smooth the data sometimes to much.
Have any of you had something similar with it?
Maybe there are some good ferret functions to interpolate ice field which is 0 or 1.
I attach two graphics for better explanation.
Kind regards,
Szymon Roziewski
