Method Overview

Method Details

fromLatitudeLongitude(coordinates, spatialReference){Point}static

Parses coordinates in latitude/longitude notation, and returns a Point representing that location. The coordinates may use decimal degrees, degrees and decimal minutes, or degrees, minutes, and seconds format. The spatial reference provided must have an ellipsoid and datum matching those used by the source of the latitude/longitude string. If no spatial reference is provided, it is assumed the latitude/longitude coordinates are in WGS84.

Supported characters

Symbol	Character	Name	Unicode number	HTML code
Degree	*	Asterisk	U+002A	*
	^	Circumflex Accent	U+005E	^

The latitude/longitude string may contain leading and trailing whitespace, and may also contain a space, comma, or vertical bar symbol to separate the latitude from the longitude. It may also contain the characters 'N', 'S', 'E' and 'W', or use a minus (-) symbol to indicate the hemisphere of each value.

Latitude/longitude notation examples:

• 55 56 39.123N 003 09 43.034W
• 55°56′39″N 3°09′43″W
• 55~56.65205', -003~09.71723'
• 55.9442008* | -3.1619539*

Parameters:

coordinates String The latitude/longitude notation string for the coordinates.

spatialReference SpatialReference optional A spatial reference object representing a geographic coordinate system. If null, WGS84 will be used.

Returns:

Type	Description
Point	Returns a point with the location from the coordinates string in the spatial reference provided.

fromMgrs(coordinates, spatialReference, conversionMode){Point}static

Parses coordinates in Military Grid Reference System (MGRS) notation, and returns a Point representing that location. The spatial reference provided must have an ellipsoid and datum matching those used by the source of the MGRS string. If no spatial reference is provided, it is assumed the MGRS string is referenced to WGS84.

Note that the choice between zone 01 and 60 has no impact when reading from an MGRS notation string. The MGRS string can contain leading and trailing whitespace and can have whitespace between the grid zone designator, the 100km square identifier, and the numerical eastings and northings.

MGRS notation examples:

• 30UVG898998
• 30UVG 89885 99877

Parameters:

coordinates String The MGRS notation string for the coordinates.

spatialReference SpatialReference A spatial reference object representing a geographic coordinate system referenced by the MGRS coordinates. If null, WGS84 will be used.

Returns:

Type	Description
Point	Returns a point with the location from the MGRS string in the spatial reference provided.

fromUsng(coordinates, spatialReference){Point}static

Parses coordinates in United States National Grid (USNG) notation, and returns a Point representing that location.

The spatial reference provided must have an ellipsoid and datum matching those used by the source of the USNG string. If no spatial reference is provided and the USNG string is suffixed with "(NAD 27)", it is assumed the USNG string is referenced to NAD 27. If no spatial reference is provided and no such suffix exists, it is assumed the USNG string is referenced to WGS84.

USNG notation examples:

• 13TFJ 23 59
• 13TFJ2374159574

Parameters:

coordinates String The USNG notation string for the coordinates.

Type	Description
Point	Returns a point with the location from the USNG string in the spatial reference provided.

fromUtm(coordinates, spatialReference, conversionMode){Point}static

The spatial reference provided must have an ellipsoid and datum matching those used by the source of the UTM string. If no spatial reference is provided, it is assumed the UTM string is referenced to WGS84. The UTM string can contain leading and trailing whitespace and can have whitespace between the zone and latitude designator and the numerical eastings and northings.

UTM notation examples:

• 30U 489885 6199877

toLatitudeLongitude(point, format, decimalPlaces){String}static

Returns formatted coordinates in latitude/longitude notation representing the given point's location.

The latitude/longitude string will contain a space separating the latitude from the longitude value, and the characters 'N' or 'S', and 'E' and 'W', to indicate the hemisphere of each value. The string will also contain spaces separating the components (degrees, minutes, seconds) of each value. The precision of the output is controlled by both the format and decimalPlaces parameters.

For example:
