<div style="margin-bottom: 0.5em">via <a href="http://slashgeo.org" class="f">Slashgeo.org</a> by Satri on 10/22/12</div><br style="display:none">
<p>We mentioned <a href="http://slashgeo.org/2010/10/15/TanDEM-X-and-TerraSAR-X-DEM-New-3D-mapping-world">TanDEM-X before</a>, <a href="http://slashgeo.org/search/node/terrasar-x">TerraSAR-X too</a>, and global DEMs like <a href="http://slashgeo.org/search/node/srtm-dem">SRTM-DEM</a> and <a href="http://slashgeo.org/2011/10/26/ASTER-Global-DEM-GDEM-Version-2-Released-Significant-Updates">ASTER GDEM</a>, and there's going to be a <a href="http://www.directionsmag.com/articles/worlddem-reaching-new-heights/285162">new major global DEM available in 2014, WorldDEM</a>.</p>
<p>From the DM article:<em> "The TanDEM-X mission is to generate a global digital elevation model - WorldDEM - of unprecedented quality, accuracy and coverage. This DEM is intended to be the replacement dataset for SRTM and will be available in 2014 for the Earth’s entire land surface - pole to pole. The accuracy of the WorldDEM will surpass that of any satellite-based elevation model available today and will have the following unique features:</em></p>
<ul>
<li>
<em>Vertical accuracy of 2m (relative) and 10m (absolute)</em></li>
<li>
<em>12m x 12m raster</em></li>
<li>
<em>Global homogeneity</em></li>
<li>
<em>Highly consistent dataset as a result of an initial global data collection window of 2.5 years and the opportunity to continue to collect locally beyond the initial collection period</em></li>
<li>
<em>No need for ground control information due to the high geometric precision of German sensors "</em></li>
</ul>
