Unidata Upgrading To TDS 4.2

Addition of Server Description in threddsConfig.xml

Server information can now be provided in the threddsConfig.xml file (more details here): 

<serverInformation>
    <name>Initial TDS Installation</name>
    <logoUrl>threddsIcon.gif</logoUrl>
    <logoAltText>Initial TDS Installation</logoAltText>

    <abstract>Scientific Data</abstract>
    <keywords>meteorology, atmosphere, climate, ocean, earth science</keywords>

    <contact>
      <name>Support</name>
      <organization>My Group</organization>
      <email>support@my.group</email>
      <!--phone></phone-->
    </contact>
    <hostInstitution>
      <name>My Group</name>
      <webSite>http://www.my.site/</webSite>
      <logoUrl>myGroup.gif</logoUrl>
      <logoAltText>My Group</logoAltText>
    </hostInstitution>
</serverInformation>

This includes some basic descriptive information about the server; a name, logo, and web site URL for the hosting institution; and contact information.

NOTE: Some of this information was previously (TDS 4.0 and 4.1) provided in the htmlSetup section. Use of the htmlSetup section for that information is now deprecated (though still supported, for now).

Addition of ncISO (as of TDS 4.2.4)

The TDS distribution now includes the ncISO package from NOAA/NGDC (many thanks to Dave Neufeld and Ted Habermann).

For details on enabling the ncISO services and applying them to datasets, see the TDS ncISO page.

Changes to WMS Configuration

Replaced OGCMeta.xml

The OGCMeta.xml file has been replaced by some of the informatino in the serverInfo element in the threddsConfig.xml file.

WMS Options in threddsConfig.xml

The following shows all the configuration options available in the WMS section of the threddsConfig.xml file with the default values shown (more details here): 

<WMS>
  <allow>false</allow>
  <allowRemote>false</allowRemote>
  <paletteLocationDir>/WEB-INF/palettes</paletteLocationDir>
  <maxImageWidth>2048</maxImageWidth>
  <maxImageHeight>2048</maxImageHeight>
</WMS>

We recommend that you include in the threddsConfig.xml file only the options you want to change. As a first pass, we recommend the following: 

<WMS>
  <allow>false</allow>
</WMS>

Additional WMS Configuration File

The WMS service now uses a new configuration file for a number of more detailed WMS configuration options, mainly focused on the styling of WMS images. Similar to the threddsConfig.xml file, the WMS configuration file (wmsConfig.xml) is found in the ${TOMCAT_HOME}/content/thredds directory. A detailed description of the wmsConfig.xml file can be found at the MyOcean "Detailed WMS Configuration" page.

If you are installing a new TDS, you should find a default wmsConfig.xml file (along with other configuration files) in your content/thredds directory after you first deploy the TDS. If you are upgrading from a TDS version before version 4.2.20100615.*, you will have to copy the default file from TOMCAT_HOME/webapps/thredds/WEB-INF/altContent/startup/wmsConfig.xml.

Change to CRS List in WMS GetCapabilities Documents

The number of CRS listed in the WMS GetCapabilities documents has been reduced between TDS 4.1 and 4.2. More information is available at this FAQ entry.

Change in How FMRC Datasets Are Configured

The datasetFmrc element has been deprecated in favor of the new featureCollection element. Details on using the featureCollection element and converting datasetFmrc elements to featureCollection elements can be found here.

Avoid java.util.prefs warnings in the catalina.out log

This is only an issue if you have enabled WMS and those services are being accessed.

You can avoid getting java.util.prefs warning in your catalina.out log file by following the configuration steps given in the TDS FAQ on this issue.
