Constructor & Destructor Documentation

DUNE::Coordinates::WMM::WMM ( void  )


By default it looks up WMM 2015 data files in the '../etc/wmm' directory relative to the location of the current executable.

References DUNE::FileSystem::Path::applicationFile().

DUNE::Coordinates::WMM::WMM ( const FileSystem::Path root)


WMM 2010 files will be searched within 'root/wmm'.
