Subfields

 
ǂa Direct reference method

The system of objects used to directly represent space in the data set.

352     Vector.
ǂb Object type

The specific type of point vector or raster graphic objects used to locate geometric locations in a data set.

352     Point : ǂb Entity point.
352     Vector : ǂb Network chain, non-planar graph.
352     Raster : ǂb pixel.
ǂc Object count

The number of each point or vector object type used in a data set.

352     Vector : ǂb GT-polygon composed of chains ǂc (70).
ǂd Row count

The maximum number of raster objects along the coordinate (y) axis. Use row count with rectangular raster objects.

352     Raster : ǂb Grid cell ǂd (20,880 x ǂe 43,200).
ǂe Column count

The maximum number of raster objects along the abscissa (x) axis. Use column count with rectangular raster objects.

352     Raster : ǂb pixel ǂd (12,343 x ǂe 9,438) ; ǂq TIFF.
ǂf Vertical count

The maximum number of raster objects along the vertical (z) axis. Use vertical count with rectangular volumetric raster objects (voxels).

352     Raster : ǂb pixel ǂd (13870 x ǂe 15951) ; ǂf 1 ; ǂq TIFF.
ǂg VPF topology level

The level of completeness of the topology carried by the data set. Use levels defined in MIL-STD-2407, Department of Defense, Interface Standard for Vector Product Format (http://earth-info.nga.mil/publications/specs/printed/2407/2407_VPF.pdf).

352     Vector : ǂb node ǂc (3,252) ; ǂg 2.
ǂi Indirect reference description

A description of the graphic features addressing schemes or other means through which locations are referenced.

352     Vector : ǂi 100 year floodplain boundary, 500 year floodplain boundary.
ǂq Format of digital image

A description of the method of referencing and the mechanism used to represent graphic information in a data set. Include the type of storage technique used and the number of items in the data set.

352     Vector : ǂb Point ǂc (13671), ǂb string ǂc (20171), ǂb GT-polygon composed of chains ; ǂc (13672) ; ǂq ARC/INFO export.
352     Raster : ǂb pixel ǂd (5,000 x ǂe 5,000) ; ǂq TIFF.
