DUNE::Coordinates::WMM::WMM

(

void

)

Constructor.

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

const FileSystem::Path &

root

)

Constructor.

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

Parameters

[in]

root

root path for searching WMM 2010 data files
