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=string  [output=string]   [--overwrite]  [--verbose]  [--quiet]

   Flags:
       -f
           Input map is in Matlab format

       -z
           Create a 3D vector points map from 3 column Matlab data

       --overwrite
           Allow output files to overwrite existing files

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       input=string
           Name of input file in Mapgen/Matlab format

       output=string
           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.
