Greeting Evan,
I see what is happening now. I exposed some new default WMS config options
that were available in edal-java but not yet used by the TDS. As a result,
the wmsConfig.xml file needs to be modified to include the new options in
the default section. The new default section that ships with the TDS looks
like this:
<defaults>
<!-- The global defaults. All elements are mandatory -->
<allowFeatureInfo>true</allowFeatureInfo>
<defaultColorScaleRange>-50 50</defaultColorScaleRange>
<defaultAboveMaxColor>#000000</defaultAboveMaxColor>
<defaultBelowMinColor>#000000</defaultBelowMinColor>
<defaultNoDataColor>extend</defaultNoDataColor>
<defaultOpacity>100</defaultOpacity>
<defaultPaletteName>psu-viridis</defaultPaletteName>
<defaultNumColorBands>20</defaultNumColorBands>
<logScaling>false</logScaling>
<!--Deprecated: intervalTime (does not work, to be removed in v6)-->
<intervalTime>false</intervalTime>
</defaults>
If you have not modified anything in your current wmsConfig.xml, you may
delete it and restart the TDS, which will cause a new, updated version of
the default config to be created.
I will modify the release notes on github and the docs to call this
important update step for those using wms - my apologies. Note that you
also may need to remove the projection database files as part of the
upgrade to 5.6 (${tds.content.root.path}/thredds/cache/edal-java/epsg/.h2),
which is related to an incompatible upstream change.
Cheers,
Sean
