      Hello

      one month ago, I worked with SARPROZ on TerraSAR-X images in Tehran area. everything was ok. But Now, I faced with this message for DEM.

      leggi_srtm: Warning! file D:\Tehran\..\SRTM\N35E051.hgt is all zeros!!

      leggi_srtm: Warning! file D:\Tehran\..\SRTM\N36E051.hgt is all zeros!!

      This can not downloag srtm and the value of them is zero.

      Please guide me.

      Regards

      The tool automatically downloads SRTM files from internet

      If anything fails, a message is printed but the tool
      does not stop running

      If a SRTM file is not found, it is created and filled with zeros

      To re-download a file that was filled with zeros, delete it (the software will warn you if a
      file filled with zeros is found)

      SRTM files can be manually placed in DirSite/../SRTM

      Please update your software version (check previous posts in the forum about that), if it is old, it is pointing to obsolete SRTM repositories
      best
