 [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. 
 
-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].

+TuiView 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:
+{{{
+export TUIVIEW_ALLOW_NOGEO=YES
+}}}
+on Linux/OS X, or:
+{{{
+set TUIVIEW_ALLOW_NOGEO=YES
+}}}
+on Windows.
+
+If 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:
+{{{
+export GDAL_PAM_ENABLED=ON
+}}}
+on Linux/OS X, or:
+{{{
+set GDAL_PAM_ENABLED=ON
+}}}
+on 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.
