This program downloads and installs the datasets used by the
|
|
GeographicLib::$CLASS class and the $TOOL tool to compute
|
|
gravity fields. $MODEL is one of more of the names from this
|
|
table:
|
|
|
|
size (kB)
|
|
name degree tar.bz2 disk
|
|
egm84 18 27 26
|
|
egm96 360 2100 2100
|
|
egm2008 2190 76000 75000
|
|
wgs84 20 1 1
|
|
grs80 20 1 1
|
|
|
|
The size columns give the download and installed sizes of the datasets.
|
|
In addition you can specify
|
|
|
|
all = all of the supported gravity models
|
|
minimal = egm96 wgs84
|
|
|
|
-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.
|
|
|
|
