<div>Hi,</div><div> </div><div>Try this site, they have lots of other data available as well.</div><div> </div><div><a href="http://glcf.umd.edu/data/">http://glcf.umd.edu/data/</a></div><div> </div><div>or more specifically</div>
<div> </div><div><a href="http://glcf.umd.edu/data/srtm/">http://glcf.umd.edu/data/srtm/</a>.</div><div> </div><div>They all also have an interactive map, though a bit fiddly to select and download data from.</div><div> </div>

<a href="http://eoweb.dlr.de:8080/index.html" target="_blank">http://eoweb.dlr.de:8080/index.html</a><br>

"The X-band SRTM DEM data are provided in DTED format. Detailed<br>
information on the DTED format<br>
can be found in the document 'Product Description of the SRTM<br>
DTED-Format' (SRTM/PD-03/11/03)<br>
available at <a href="http://www.dlr.de/srtm/docs/SRTM-XSAR-DEM-DTED-1.1.pdf" target="_blank">http://www.dlr.de/srtm/docs/SRTM-XSAR-DEM-DTED-1.1.pdf</a>.<br>
<br>
The DEM and HEM data are in geographic (Lat/Long) projection, datum<br>
WGS84. The elevation values<br>
are also WGS84, as specified in the product description of the SRTM<br>
DTED-format.<br>
<br>
The DEMs inside the compressed archive are distributed as individual<br>
files, i.e. they are not<br>
mosaicked into one large DEM file. Each DEM covers an area of 15' by<br>
15'. The filename of the<br>
individual DEM file specifies the bottom left coordinate of the<br>
corresponding 15' by 15' DEM tile.<br>
<br>
One pixel of the DEM files corresponds to approximately 25 m x 25 m on<br>
the ground. The elevation<br>
values are provided at a resolution of 1 m. The horizontal accuracy of<br>
the SRTM X-band DEMs is ±20<br>
m (abs.) / ±15 m (rel.), both 90% CE. The vertical accuracy is ±16 m<br>
(abs.) / ±6 m (rel.), both 90% LE.<br>
Precise information on vertical and horizontal accuracies for<br>
individual tiles can be found in the<br>
accuracy description record (ACC) of the DTED file. "<br>
<br>
I tried to access the public portal, but I just got the "Loading java<br>
virtual machine" message.<br>
Anyone here, who can access the data and is it really available to the public?<br>
