On-demand (user-specified) WMS:

The HDDS system supports a WMS on-demand delivery option based on user selections within the HDDSExplorer interface. This type of user-specified WMS output is available for all public domain and restricted imagery on HDDS. 

The on-demand WMS delivery option is defined and selected by the user as part of the HDDSExplorer search and delivery request.

Once delivered to the end user, the on-demand WMS layers will remain available for 2 weeks.
