Inserting a US National Grid Reference Box element (Defense Mapping)

The U.S. National Grid Reference Box references the Universal Transverse Mercator (UTM) grid zone designator and the two-letter location identifiers of the 100,000-meter grid squares that cover the extent of the active data frame. Multiple combinations of grid zone identifiers and 100,000-meter grid squares are possible when the data frame extent crosses zone boundaries.

Remarque :

The scale must be set to 1:250,000 or larger to use this tool.

Grid zone designations are unique identifiers specified with numbers from 1–60 for the UTM zones and letters C through X (skipping I and O) specifying 8 degrees of latitude each, starting at 80 degrees south and going to 84 degrees north.

Each grid zone is subdivided into 100,000-meter grid squares specified by two-letter identifiers, with the first letter indicating a column and the second letter indicating a row.

The information displayed in the reference box, including the grid zone designation and the two-letter location identifiers of the 100,000-meter grid squares, is initially determined from the map extents. This information can be further modified on the National Grid Reference Box Properties dialog box.
