Hi,

in v.split:
I wonder what units are be used as length in a lat-lon environment?

Are these degrees?

Why isn't there an option for m, km,..?

Thanks in advance,
Achim

I am afraid yes since it uses Vect_line_length(). Certainly this is
rather useless.

The doxygen documentation for that function suggests:
   "For Lat-Long use Vect_line_geodesic_length() instead."

Why isn't there an option for m, km,..?

The "easiest" way would be to manage things as done in v.distance.

Please open an enhancement report in trac for this.
