FIELD DEFINITION AND SCOPE
Description of the method of referencing and the mechanism used to represent graphic
information in a data set. This information consists of the type of storage technique
used, the number of items in the data set, and the format in which the data is
stored.
GUIDELINES FOR APPLYING CONTENT DESIGNATORS
■ INDICATORS
- Both indicator positions are undefined; each contains a blank (#).
■ SUBFIELD CODES
$a - Direct reference method System of objects used to directly represent space in the data set.
$b - Object type Specific type of point, vector, or raster graphic objects used to locate geometric
locations in a data set.

$d - Row count Maximum number of raster objects along the ordinate (y) axis. Row count
is used with rectangular raster objects.
$e - Column count Maximum number of raster objects along the abscissa (x) axis. Column
count is used with rectangular raster objects.
$f - Vertical count Maximum number of raster objects along the vertical (z) axis. Vertical
count is used with rectangular volumetric raster objects (voxels).
$g - VPF topology level Level of completeness of the topology carried by the data set. The levels are
defined in U.S. Department of Defense, 1992, Vector Product Format
(MIL-STD-600006) (Philadelphia, PA: Department of Defense, Defense Printing
Service Detachment Office).
$i - Indirect reference description Graphic features, addressing schemes, or other means through which locations are
referenced.
