Great, sounds like a clear consensus for using Raster. Also good to have
Jody's clarification of "raster" versus "image" - this is something I
puzzled over while documenting the various recent rendering transformations
@Andrea, all I'm talking about now is changing the metadata documentation
to use a term that is more precise and familiar to users. There are also
some emerging areas where a consistent term is needed - for example, the
issue of categorizing processes by parameter type. It's also good to have
a consistent term for use in Javadoc.
I realize that doing anything further will have some significant impacts.
I just wanted to raise the issue to establish a clear direction. Perhaps
there can be a slow drift in the direction of using "raster" in other
areas. as and when it's appropriate.
