Hi everybody,
I am starting at FOSSGIS an attempt at hexagons based on PyGRASS. After a
lengthy discussion with Sören, he convinced me to try a pragmatic approach
entirely based on Python. The first draft module is in:

More details to follow. Thank

Hello Luis,
I saw the video of the webinar of your colleague João P Leitão in
April about the hex version of the CADDIES model and I was asking
myself "is there any GIS software supporting hexagonal rasters?"
So I'm quite excited about the prospect of having support in GRASS ;)
However, I'm not

Dear Luís,
this sounds very interesting, especially the improvement for surface
flow algorithms using hexagonal grids and other mass conservation
approaches like groundwater flow, heat flow, ... .
I agree with Vaclav on this topic. I think hexagonal grids can be
stored using the compressed row

Dear friends,
I presented hex-utils at the GISTAM conference in April, here is the video:

This was before the QGis plug-in was completed, but for the rest it is pretty
much the same story.
Before the FOSS4G-E, in my mind the next phase of the project
