It sounds like you want to create a grid of specified extent and size (=
# of horizontal and vertical cells). It's pretty straightforward to
code this up as a nested loop which creates Envelopes.
I don't know of any Java code that's packaged up and ready to use.
You can do this fairly easily with JEQL, however.

Does anyone know of (or have) code that will take an envelope and
break it up into smaller envelopes of equal size? (I didn't see a
method in the Envelope class that performed this operation.)
Here is my use case:
I've got some shapefiles that are too large to work with in OpenJUMP.
I want to split one of these large shapefiles into a smaller shapefile
that I can work with. To do this I thought I could access the envelope
that covers all features in the Shapefile. I'd split this into a
number of smaller envelopes of equal size. I'll then use code from
deegree/Geotools to iteratively access each feature in the Shapefile
on disk. I'll determine which envelope each feature fits in, and I'll
stick that feature in a new Shapefile.
Thanks for any thoughts. I'll whip up some new code if no one has
existing code to do the trick.
