Some data providers choose to implement their own custom graphical interface to ncWMS,
taking advantage of the WMS extensions: see Fig. 5 ncWMS and the Godiva2 viewer have been adapted into plug-ins for the widely-used Unidata THREDDS Data Server (Signell et al., 2008; Blower et al., 2009b),
which is used by organizations such as NOAA and the US Geological Survey for serving environmental data; the ncWMS/Godiva2 plug-ins allow all these datasets to be interactively browsed on the Web.
