SRTM FTP Site Changed

It seems like the Shuttle Radar Topography Mission (SRTM) data site is not available at NASA anymore. I used to use that FTP site for generating DEMs for my study areas.

 

There are also other tools such as Makedem from Noel Gourmelen, and construct_dem from TU Delft.  Construct_dem.sh currently comes with the Doris Software.Both of these scripts use the old ftp site at NASA: e0srp01u.ecs.nasa.gov, which does not work anymore.

 I couldn't find another FTP site, however I found a HTTP site hosted by USGS following the same folder structure and naming convention. It is located at: http://dds.cr.usgs.gov/

However also be aware that the "/srtm/version2" folder does not exist anymore. The new name for the version 2 product is "/srtm/version2_1". So you will have to update the scripts as well. If I get around to fixing one of these codes, I'll publish it here. 

Update on 20091218: I still do not have a script for automatic DEM retrieval using lat/lon. However I noticed that the link above does not work by itself. So here are the complete links:

 http://dds.cr.usgs.gov/srtm/version1/

http://dds.cr.usgs.gov/srtm/version2_1/

Of course if you want to manually download the srtm data you can use the Earth Explorer Service. You'll have to register but the SRTM data is free-of-charge.
