<h2>DESCRIPTION</h2>
<em>r.in.srtm</em> imports SRTM hgt files into GRASS.
SRTM Version 1 and improved Version 2 data sets can be downloaded from
NASA at this site:<br>
<a href="http://dds.cr.usgs.gov/srtm/">http://dds.cr.usgs.gov/srtm/</a>
<p>
Gap-filled SRTM Version 3 data can be downloaded from USGS at this site:<br>
<a href="http://e4ftl01.cr.usgs.gov/SRTM/SRTMGL3.003/2000.02.11/">http://e4ftl01.cr.usgs.gov/SRTM/SRTMGL3.003/2000.02.11/</a>
<h2>NOTES</h2>
SRTM tiles are of 1 degree by 1 degree size. The SRTM filename contains the
coordinates which refer to the <b>center</b> of the lower left pixel (e.g., N51E010:
lower left cell center at 10E, 51N). To identify a tile name, a grid can be easily
visualized in the GRASS monitor:
<div class="code"><pre>
d.grid size=1
</pre></div>
To import TOPEX/SRTM30 PLUS data, use <em>r.in.bin</em>.
