Thank you! -- I have been reading this thread and wondering what's going
on. "simple geometries" can indeed represent this kind of grid, but that's
not what it's intended for, and it's not a great way to do it. Nor is
(it's a major pet peeve of mine that the geopatial data statndards are
require you to tweak a grid as a bunch of unorganized polygons....)
And cell bounds aren't really for this purpose either.
Maybe I am missing the OP's use case, but an unstructured mesh should be
represented by the UGRID standard -- that's what it's for. Does it not work
for the OP's case somehow?
