If we have to change I prefer raster.
However... do we have to change, and how extensive is the change in terms
going to be?
We have Coverage all over our API, documentation, and user interfaces, and
it has been
there for 10 years, changing it all would me a massive undertaking and
would trip people
already used to the old terminology.
If we start using raster more but don't change the existing references to
Coverage are
we going to improve things, or just make them more confusing?
