[GRASS-user] Points to area workflow

[Thomas Adams]

Micha & Rich:

I was able to successfully import & display the boundary from Rich's
example:

v.in.ascii --overwrite
input=/media/teaiii/development/grass/test_analysis_boundary.dat
output=test_analysis_boundary format=standard separator=space

I used GRASS 7.6 with the GUI, but the command above worked...
