Projected Grid Northing Prefix Token Tool

Calculate projected grid northing prefix token from explicit caller-supplied inputs.

Description

Concatenate the three strings.

Coordinate labels and tokens encode an axis order, sign convention, or formatting policy. Numeric compatibility and text formatting can diagnose ambiguity, but neither establishes the actual coordinate reference or location.

Concatenate the three strings.

When to use this tool

Use Projected Grid Northing Prefix Token when you need a supplied geographic label or coordinate-convention diagnostic.

How to use the tool and how it works

  1. Enter zone, northing, separator. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read text. Use the output convention below.

Require a zone of ASCII letters, digits, and hyphens, northing as signed decimal text with digits before any decimal point, and a separator without line breaks. Concatenate the three strings.1

Limitations and assumptions

  • An empty separator is accepted; exponential numeric notation is rejected. No projection, official zone, coordinate unit, or northing range is verified.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.

Alternative or Complementary methods

Read authoritative coordinate metadata when the actual axis order or reference system matters. Keep original numeric precision and explicit sign conventions rather than inferring them from a plausible label.
