[Geographiclib-announce] World Magnetic Model wmm2015v2 now available (2019-02-05)

[Charles K. <ch...@ka...>]

The World Magnetic Model wmm2015v2 is now available for use with
GeographicLib.  You can download it from

   https://sourceforge.net/projects/geographiclib/files/magnetic-distrib/

This "out of cycle" release is described at

   https://www.ncei.noaa.gov/news/world-magnetic-model-out-cycle-release
   https://www.nytimes.com/2019/02/04/science/north-magnetic-pole-model.html

The original wmm2015 is still available, but this labeled "deprecated"
by NOAA.

GeographicLib needs no modification to use wmm2015v2; just install the
model as described in

   https://geographiclib.sourceforge.io/html/magnetic.html#magneticinst

but note that the geographiclib-get-magnetic script will complain that
wmm2015v2 is an unknown model.

With the next release of GeographicLib, the MagneticField utility will
use wmm2015v2 as the default model.
