Seth, Thank you for your support and suggestions, they lead me to
the problem which was the fact that somewhere along the line some
filenames changed and CONFIG ON_MISSING_DATA "IGNORE" masked that
problem.<br>
<br>
So things are working as expected after fixing file names and few
other minor computational issues.<br>
<br>
Thank you all for this wonderful software suite!<br>

<div>HI Steve,</div>

<div>Yes, it is the MapServer logs that might have something
useful. You can also increase the LAYER logging and add in GDAL
logging by adding the following to the Mapfile:</div>
<div><br>
</div>
<div> CONFIG "CPL_DEBUG" "ON"</div>
<div> CONFIG "PROJ_DEBUG" "ON"</div>
<div> DEBUG 5</div>
<div> </div>
<div> LAYER</div>
<div> DEBUG 5</div>
<div><br>
</div>
<div>I wouldn't worry too much about the querying until you can
see output in the map. I'd probably try a few things to narrow
it down:</div>
<div><br>
</div>
<div>- does the LAYER work if you switch the data to the ssh
layer?</div>
<div>- does the LAYER work if you use the image directly without
the .vrt?</div>
<div>- maybe get the EXTENT from QGIS or GDAL in EPSG:4326 and add
the EXTENT to the layer.</div>
<div><br>
</div>
<div>In my experience, blank layers are usually related to extent
or projection, but it could be something else.</div>
