Maximum height (top)
Height interval
Height interval above the earth or water surface. The minimum height value is expressed first and then the maximum height value. Values increase in the upward direction.

Degrees from north
Distance along ray
Radial horizontal offset
Offset expressed as a distance along a ray that originates from a central point. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate.
2D
Interval along a horizontal or longitudinal ray. The first coordinate is the angle from north expressed in degrees of the longitudinal array. The second coordinate is the minimum distance along the ray at which the longitudinal interval begins. The third coordinate is the maximium distance along the ray at which the longitudinal interval ends.

Longitudinal interval
Degrees from north
Depth below the earth or water surface along a non-vertical line. The first coordinate is the angle of the ray from north expressed in degrees. The second coordinate is the angle of the ray from horizontal expressed in negative degrees. The distance along the ray is expressed as a positive number that increases with distance along the ray.

Minimum depth (top)
Depth interval below the earth or water surface. The mininum depth value is expressed first and then maximum depth value. Values are expresssed as negative numbers and become more negative in the downward direction.

Depth below the earth or water surface. Values are expressed as negative numbers and become more negative in the downward direction.
Offset expressed using cartesian coordinates where X is distance along axis aligned with true north, Y is distace aligned with true east, and Z is distance aligned straight up. Depths are expressed a negative numbers. The origin of the coordinate system is typically defined in the site description.

Distance along ray
Depth
Offset expressed as a distance along a ray that originates from a central point with a third coordinate that indicates the depth below the earth or water surface. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate. The depth below the earth or water surface is expressed as the third coordinate.

Height, directional
Height above the earth or water surface along a non-vertical line. The first coordinate is the angle of the ray from north expressed in degrees. The second coordinate is the angle of the ray from horizontal expressed in positive degrees. The distance along the ray is expressed as a positive number that increases with distance along the ray.
