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

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".

The user 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.
