342 - Geospatial Reference Data (R)
MARC 21 Bibliographic - Concise

Description of the frame of reference for the coordinates in
a data set. To work with a data set a user must be able to
identify how location accuracy has been affected through the
application of a geospatial reference method, thus enabling the
user to manipulate the data set to recover location
accuracy.
Indicators
First - Geospatial reference dimension
0 - Horizontal coordinate system
1 - Vertical coordinate system
Second - Geospatial reference method
0 - Geographic
1 - Map projection
2 - Grid coordinate system
3 - Local planar
4 - Local
5 - Geodetic model
6 - Altitude
7 - Method specified in $2
8 - Depth
Subfield Codes

$n - Azimuth measure point longitude or straight vertical
longitude from pole (NR)
$o - Landsat number and path number (NR)
$p - Zone identifier (NR)
$q - Ellipsoid name (NR)
$r - Semi-major axis (NR)
