[R-sig-Geo] Hex GIS, (was) Moving-window ...

[Frank Hardisty]

Denis and All,

The best thing out there is probably the "hexbin" package in R, based
on Dan Carr's work. It's not a GIS, however. Hexagons do have some very
nice properties for spatial analysis.

Does anyone know of a GIS based on a regular hexagon tessellation
rather
than on squares or rectangles?  (There was a project twenty some years
ago called System X developed for the Navy by Dean Lucas that started
into commercialization but never finished as far as I know.)
