SYNOPSIS

v.in.lines
v.in.lines help
v.in.lines [-z] input=string output=string [fs=character] [--overwrite] [--verbose] [--quiet]

Flags:

-z: Create a 3D line from 3 column data
--overwrite: Allow output files to overwrite existing files
--verbose: Verbose module output
--quiet: Quiet module output

Parameters:

input=string: Name of input file (or "-" to read from stdin)
output=string: Name for output vector map
fs=character: Field separator; Default: |

DESCRIPTION

Imports a stream of ASCII x,y[,z] coordinates as a line or series of lines.

NOTES

Input ASCII coordinates are simply a series of "x y" data points. Lines are separated by a row containing "NaN NaN".

You can import 3D lines by providing 3 columns of data in the input stream and using the -z flag.

This script is a simple wrapper around the v.in.mapgen module.
