Re: [Geotools-gt2-users] How to extract data out of a GEOTIFF file

[Jody G. <jod...@gm...>]

I am not sure your single band geotiff *has* color information? Usually you
would setup a raster symbolizer to map coverage values to a color? I
recommend stopping the application in the debugger and exploring the
resulting image and color model to see if you can determine what is going
on.
