geographiclib-get-gravity −− a GeographicLib administrative tool
geographiclib-get-gravity downloads and installs the gravity datasets used by GeographicLib, <https://geographiclib.sourceforge.io>. For documentation, supply the −h option:
geographiclib-get-gravity −h
By default, the datasets are installed in /usr/share/GeographicLib/gravity and the script requires write access to this directory.
