I guess I don't get the process that the nice image is going through. Are you having to pre-reproject it to Mercator before slicing it up for the exact Google maps zoom levels? Or do you just provide it in 4326 and google maps takes care of reprojecting it?
It's in latlong and letting Google Maps do whatever it does; or Mapserver reproject it. Reprojecting it ahead of time made no difference.
Are the source PNGs paletted or RGB 24bit?
The original PNGs are 8-bit paletted. Presented to me is a RGB TIFF, because I knew that paletted wasn't going to cut it.
Selecting PROCESSING "RESAMPLE=BILINEAR" and giving it 24bit RGB input files should give something fairly similar I'd think.
Nope. I've already tried all 4 resampling algorithms, 24 bit TIFFs, and overviews with -r average, and the oversample_ratio directive. No significant effect. That current combination is up now if you want to see.
