Method ToUsng

Returns a formatted coordinate string in United States National Grid (USNG) notation representing the given MapPoint's location.

public static string ToUsng(MapPoint point, int precision, bool addSpaces)

Type	Name	Description
MapPoint	point	The location to be represented in USNG notation. It must have a SpatialReference set.
Int32	precision	The precision with which to represent the coordinate. Value is expected to be between 0 to 8 (inclusive), and will be clamped if necessary.
Boolean	addSpaces	If `false`, the generated string contains no spaces. If `true`, a space separates the grid zone designator, the 100km square identifier, and the numerical easting/northing values.

Type	Description
String	A USNG notation string representing the position of the given MapPoint.

The precision value controls the number of digits used to represent each numerical easting and northing value within the USNG string. For example:

`precision` parameter value	`addSpaces` parameter value	Example output	Approximate precision (to 1 significant figure)
0	false	`13TFJ`	100km
1	false	`13TFJ25`	10km
2	false	`13TFJ2359`	1km
3	false	`13TFJ237595`	100m
4	false	`13TFJ23745951`	10m
5	false	`13TFJ2374359512`	1m
0	true	`13T FJ`	100km
1	true	`13T FJ 2 5`	10km
2	true	`13T FJ 23 59`	1km
3	true	`13T FJ 237 595`	100m
4	true	`13T FJ 2374 5951`	10m
5	true	`13T FJ 23743 59512`	1m

If the point's SpatialReference is NAD 27, then a suffix is added to the end of the formatted string. For example:

`precision` parameter value	`addSpaces` parameter value	Example output	Approximate precision (to 1 significant figure)
4	false	`13TFJ23795929 (NAD 27)`	10m
2	true	`13T FJ 23 59 (NAD 27)`	1km

Type	Condition
ArgumentNullException	`point` is `null`.
ArgumentException	`point` does not have a spatial reference.
