Thanks, I already browsed those once and I missed the importance of 01format.
 I'll have a better look.

Thanks Jody, I will first have to study a bit though, don't want to
torment you before I do not have a better picture on the
coverage-imageio "mappings".


One question though: I didn't expect that many deprecated classes at
that level. I checked out the arcgrid plugin and there are some of
them. Is that ok? I'm pretty sure I have the right code.... but...
