342 Subfield $v - Local planar, local, or other projection or grid description:

Subfield $v contains a description of a local planar system (any right-handed planar coordinate system of which the z-axis coincides with a plumb line through the origin that is aligned locally with the surface of the Earth) when the second indicator has value 3.

Subfield $v contains a description of a local system (any coordinate system that is not aligned with the surface of the Earth and its orientation to the surface of the Earth) when second indicator has value 4.

Subfield $v contains a complete description for an undefined projection used for the data set. The information provided includes:

the name of the projection

the names of the parameters and values used for the data set

the citation of the specification for the algorithms that describe the mathematical relationship between the Earth and the plane for the projection

when the second indicator has value 1.

Subfield $v contains a complete description for an undefined grid system used for the data set. The information provided includes:

the name of the grid system

the names of the parameters and values used for the data set

the citation of the specification for the algorithms that describe the mathematical relationship between the Earth and the coordinates of the grid system

when the second indicator has value 2.
