343 Planar Coordinate Data

Field definition and scope:

Field 343 contains information about the coordinate system developed on a planar surface. The information is provided to allow the user of a geospatial data set to identify the quantities of distances, or distances and angles. These define the position of a point on a reference plane onto which the surface of the Earth has been projected.

The National level record requirement for this field is Mandatory if applicable.

Field 343 is repeatable.

Guidelines for applying content designators:

For indicator and subfield code definitions and examples, National-level (NLR) and Minimal-level (MLR) record requirements, and designator repeatability, see table below:

Position	Description	NLR	MLR	Repeatability
Field 343	Planar Coordinate Data	A	O	R
Indicator:
First	Undefined; contains a blank	M
Second	Undefined; contains a blank	M

Subfield code:
