Is there any way to force my WCS requests to use bilinear interpolation?
I've tried playing with the layer's publishing tab but that seems to have no
effect. All of my logs for WCS getCoverage always say:
"interpolationMethod = nearest neighbor"

Ok, I got it to take my interpolation setting (see below) as indicated by my
geoserver log files but my image always looks like the same 4 colored blocks
no matter if I select bilinear, bicubic, or nearest neighbor interpolation.
I am looking to receive an image where the colors blend into each
other(bilinear) instead of having more distinct color boundaries(nearest
neighbor). Any ideas on what I'm missing? Everything still always looks
like it's nearest neighbor.
Thanks!!!
Ashley
