Glynn:
It would be possible to implement the -a flag unconditionally,
Hamish:
I prefer to use '-a' on an as-needed basis.
...
g.region n=9975 s=25 w=25 e=9975 res=50
# ** -a at this step would align to "00" and "50" not "25" and "75"
I was reading 'unconditionally', as meaning "always", not as when
"when
given with out other conditions". I've now spotted that double meaning
but am unsure which meaning was intended. I assume the latter.
Hamish
What I thought you meant and thought was a good idea would be the
following...
g.region nsres=10 -a
...means that the region would be aligned to 10m in the NS direction
and the current resolution (whatever that is) in the EW direction.
g.region -a
...would align to the current resolution in both NS and EW
g.region -a res=10
...would align to a 10m resolution in both direction.
