[GRASS-user] Drawing a vector line with bearing/distance

[Laurent C.]

Thank you Helmut.
As I understand, m.cogo works only for geographical coordinates.
Since I am using a projected location, I just calculated the new
coordinates using basic trigonometry. It short distances, so I guess that
is alright.
