When using stereographic projection set, for example, at the south pole,
d.grid's geographical output is messy: grids are not completely traced and
the labels accumulates at the corners at various angles.

Find attached a screenshot of the output for a 1000x1000 km area centered
at the south pole, and a sample location (to reproduce the screenshot,
use: d.grid -g size=10).

Regards,

Alessandro Frigeri

Comment:

known bug.

for the stereographic images on the raster screenshots page (1,2) the
work-around I used was to use v.mkgrid in a lat/lon location which I then
pulled into the stereographic projection with v.proj.

Comment(by hamish):

hopefully the label text is a little better now. grid lines around
anomalies still need work.
