<H2>DESCRIPTION</H2>
<i>r.in.arc</i> allows a user to create a (binary) GRASS raster map layer
from an ESRI ARC/INFO ascii GRID file with (optional) title.
<p>
The ARC/INFO ascii GRID file header has 6 lines:
<div class="code"><pre>
ncols:
nrows:
xllcorner:
yllcorner:
cellsize:
</pre></div>
or alternatively (not supported by r.in.arc, but by
<a href=r.in.gdal.html>r.in.gdal</a>):
<div class="code"><pre>
ncols:
nrows:
xllcenter:
yllcenter:
cellsize:
</pre></div>
<h2>NOTES</h2>
<i>r.in.arc</i> handles floating point cell values. The <b>mult</b>
option allows the number of significant figures of a floating point cell
to be increased before importing. Multiples of ten are the most functional
multipliers.
