[GRASS-user] KEYLINE; installing new module add-on (of 7.8) in GRASS 7.6

Tue Mar 9 08:10:42 PST 2021

Sorry Stefan
I'm a real fool
In the north-south direction the values are the same
while when the direction is different, oblique, the right is yours,
because the mapcalc formula is based only on the resolution of the
raster, not on the actual distance !!
Thank you very much for the work: very useful
