DXYZ: XYZ Coordinate Difference

This record specifies 3D Cartesian coordinate difference observations. It is used in forming groups of 3D coordinate difference observations (3DD).

This record has two possible formats, a long parameter name format, and a short parameter name format. If column 10 contains an asterisk (*) the long name format is expected, otherwise the short name format is expected.

The short parameter name format is as follows:

Columns 002-005: DXYZ
Columns 010-010: (blank)
Columns 011-022: Name of from-station
Columns 024-035: Name of to-station
Columns 037-049: X-coordinate difference
Columns 051-063: Y-coordinate difference
Columns 065-077: Z-coordinate difference
Columns 079-080: Linear unit name

The long parameter name format is as follows:

Columns 002-005: DXYZ
Columns 010-010: * (asterisk)
Columns 011-041: Name of from-station
Columns 043-073: Name of to-station
Columns 075-087: X-coordinate difference
Columns 089-101: Y-coordinate difference
Columns 103-115: Z-coordinate difference
Columns 117-118: Linear unit name
