    33[http://tuiview.org/ TuiView] is an open source data viewer similar to ENVI / ERDAS Imagine, the development was funded Landcare Research NZ Ltd. It is build on top of GDAL and is capable of opening any data formats GDAL can read, including BIL, BSQ and GeoTiff. Within ARSF it is used as a general image viewer for hyperspectral data and DEMs and as part of the procedure for determining SCT values.

    5 ARSF have added a number of features to TuiView for better handling of hyperspectral data. Development of TuiView by ARSF takes place on [https://bitbucket.org/arsf/tuiview Bitbucket].

    77TuiView is opened from the command prompt by typing:

     25TuiView will not open these unmapped (e.g., level1b) files by default and will give an error about only allowing north-up images. You can force TuiView to open them by setting the environmental variable `TUIVIEW_ALLOW_NOGEO` using:
     26{{{
     27export TUIVIEW_ALLOW_NOGEO=YES
     28}}}
     29on Linux/OS X, or:
     30{{{
     31set TUIVIEW_ALLOW_NOGEO=YES
     32}}}
     33on Windows.

     35If you get an error that TuiView is unable to open the file it could be that ‘data ignore value = 0′ is set in the header and the GDAL driver is unable to handle it. You can export the environmental variable:
     36{{{
     37export GDAL_PAM_ENABLED=ON
     38}}}
     39on Linux/OS X, or:
     40{{{
     41set GDAL_PAM_ENABLED=ON
     42}}}
     43on Windows. This will create a ‘*.aux.xml’ metadata file with additional features the driver doesn’t support when TuiView opens the file. More information is available in the GDALPamDataset documentation.
