    hi
    I have 2 questions :
    1-why all of “HEIGHT WRT DEM” that Calculated and extracted in my process with sarproz are negative? log file attached.
    2-why the ext DEM (SRTM) that sarproz downloaded it automatically is 3s(arc degree) , while DEM with 1s (30m) resolution is Available on the USGS website.DEM SRTM 3S attached.

    thanks for response

    1 – check this https://www.sarproz.com/groups/sarproz-group/forum/topic/height-and-relative-height-from-ground/
    2 – Sarproz automatically loads a globally available DEM. However, if you want a differen one, you can import you own DEM in geotiff format in geographic coordinates. In the near future we will implement more automatic options.
