[gdal-dev] How to fix gdalwarp warning?

[Stephen Woodbridge]

How does one do "Converting the dataset  prior to 24/32 bit is advised."?

Warning: Input file 
/maps/images.tmp/844219fb7ca86093d82b14376b56b875/modis-chlo
ra-201402071850.tif has a color table, which will likely lead to bad 
results whe
n using a resampling method other than nearest neighbour. Converting the 
dataset
  prior to 24/32 bit is advised.

Thanks,
