<h2>DESCRIPTION</h2>
<em>v.in.mapgen</em> allows the user to import Mapgen or Matlab vector maps
into GRASS.
<h2>NOTES</h2>
This module only imports data into vector lines.
<p>The user can get coastline data in Mapgen or Matlab format from NOAA's Coastline
Extractor at <a href="http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html">http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html</a>.
<p>Matlab vector line maps are simply a series of "x y" data points. Lines
are separated by a row containing <tt>NaN NaN</tt>.
Output from Matlab with this command:
<br>
<div class="code"><pre>
save filename.txt arrayname -ASCII
</pre></div>
<p>The user can import 3D lines from Matlab by exporting a 3 column array and
using the <b>-z</b> flag.
