This program downloads and installs the datasets used by the
|
||||
GeographicLib::$CLASS class and the $TOOL tool to compute
|
||||
magnetic fields. $MODEL is one of more of the names from this
|
||||

The size columns give the download and installed sizes of the datasets.
|
||||
In addition you can specify
|
||||
|
||||
all = all of the supported magnetic models
|
||||
minimal = wmm2020 igrf13
|
||||
|
||||
-p parentdir (default $DEFAULTDIR) specifies where the
|
||||
datasets should be stored. The "Default $NAME path" listed when running
|
||||
|
||||
$TOOL -h
|
||||
|
||||
should be parentdir/$SUBDIR. This script must be run by a user with
|
||||
write access to this directory.
|
||||
|
||||
Normally only datasets which are not already in parentdir are
|
||||
downloaded. You can force the download and reinstallation with -f.
|
||||
The -f flag also let you download new models (not yet in the set
|
||||
defined by "all").
|
||||
|
||||
If -d is provided, the temporary directory which holds the downloads,
|
||||
\$TMPDIR/$NAME-XXXXXXXX or ${TMPDIR:-/tmp}/$NAME-XXXXXXXX,
|
||||
will be saved. -h prints this help.
|
||||
