Note, that the coordinates order is NORTH EAST.
To import category labels, the dig_cats file needs to be specified in OTHER INFO field.
Example ASCII vector file (store in dig_ascii/). Note the blank before entering vertex coordinates:

To (re-)set map metadata like ORGANIZATION etc. later, v.digit can be used.
The GRASS program v.out.ascii performs the function of v.in.ascii in reverse; i.e., it converts vector files in binary format to ASCII format. These two companion programs are useful both for importing and exporting vector files between GRASS and other software, and for transferring data between machines.
The input from v.in.ascii has to be placed into $LOCATION/dig_ascii (this directory must be created if not existing).
