DEM File Problem

  • I successfully installed one DEM file and then I downloaded a NED Zip folder and tried to import another file. During the import an error displayed. I think it was Error 0001, but I'm not sure.


    Now when DEM is clicked Touratech QV closes.


    Explorer list two DEM Files but i can't open the DEM folder to delete the bad DEM.


    Should I uninstall and reinstall TTQV?

  • Hi,


    "DEM-files" is at first simply a familiar expression for a huge variety
    of different elevation file formats. Even if the files have the file extension
    *.dem", this does not mean, that the format of those files, specially if
    retrieved from various sources, is the same file format.
    "NED" offers various file formats, I do not know which of them TTQV actually can read.
    The srtm3 data available here are readable by TTQV:
    http://glcf.umiacs.umd.edu/data/srtm/index.shtml


    Beside that, TTQV can import all the DEM files on sale at TTQV online shop:
    http://www.touratech.com/shops…php?cPath=1_3&language=en


    Furthermore TTQV can read the "GlobalMaper Grid" DEM-file-format. As the
    Software GlobalMapper can import almost every known DEM format. One can
    then easily export various DEMs to "GlobalMaper Grid" and use it with TTQV4.

  • Hi Jockel,


    Should I wait for a TTQV upgrade fixing the problem of dying after encountering a DEM file import error or should I uninstall and reinstall.


    I can't delete the DEM folder or install another DEM.

  • The TTQV installation is now okay and I don't need to uninstall/reinstall. After clicking the altitude location displayed at the bottom of the screen, Explorer opened displaying the DEM folder. I was able the Delete two DEMs, and then import my good DEM.


    Now everything is working as it should.
