Poking back into the old grey matter, I cant remember if any commercial GIS
applications show areas as ha, though I vaguely recally arcview having a
plugin that did. My feeling is that if adding the ability to show units in
ha doesnt require a large amount of effort it would be a nice feature to
have since its a basic working unit used by many people in land management.
