## NAME

v.in.mapgen

## 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.

You 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

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