NAME

       v.in.mapgen  - Imports Mapgen or Matlab-ASCII vector maps into GRASS.

KEYWORDS

       vector, import

SYNOPSIS

       v.in.mapgen
       v.in.mapgen --help
       v.in.mapgen   [-fz]   input=name   [output=name]    [--overwrite]   [--help]   [--verbose]
       [--quiet]  [--ui]

   Flags:
       -f

           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       input=name [required]
           Name of input file in Mapgen/Matlab format

       output=name
           Name for output vector map (omit for display to stdout)

DESCRIPTION

       v.in.mapgen allows the user to import Mapgen or Matlab vector maps into GRASS.

NOTES

       This module only imports data into vector lines.

       The user can get coastline data in Mapgen or Matlab format from NOAA’s Coastline Extractor
       at http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html.

       Matlab vector line maps are simply a series of "x y" data points. Lines are separated by a
       row containing NaN NaN.  Output from Matlab with this command:
           save filename.txt arrayname -ASCII

       The user can import 3D lines from Matlab by exporting a 3 column array and  using  the  -z
       flag.
