[GRASS-dev] latlong problem

[Martin Landa]

Hi,

there is a significant problem in LatLong location. Try the following:

g.region n=80 s=-80 w=-170 e=170 res=1;
v.in.region out=reg;
g.region n=90 s=-90 w=-180 e=180 res=1;
d.erase;d.vect reg
[1] should be [2]

I prepared a simple patch to fix this bug.

I am not sure whether it is OK. Anyway testing "(east1 - east2) > 180"
does not make sense to me... or am I wrong?

Martin
