[GRASS-user] Possible issue with ps.map

Tue Jun 1 08:28:40 PDT 2021

Good afternoon all,

I am using ps.map to create an OS map for an archaeological site and want to add the OS grid lines with their appropriate coordinates.

If I use
grid 100

It produces the lines as desired but only puts the leading 4 digits of the coordinates  and omits the 2 trailing zeros.
if however I use

grid 50

it again produces the grid but this time with the correct coordinates, all 6 digits.

I am running Grass 7.8 downloaded from Giscan.com as it is a a “working version” overcoming the as yet un resolved wxpython issue for AUR based versions.

Am I doing something wrong or is this a possible bug, either from using newer versions of wxpython (4.1.1) or in Grass?

While I am writing is the north arrow option no longer available in Grass 7.8 within ps.map? It is no longer listed in the manual for the ps.map.

Thanks for 

Dr Timothy Glyn Southern
