Property Overview

Property Details

cacheObjectreadonly

The cache is used to store values computed from geometries that need to cleared or recomputed upon mutation. An example is the extent of a polygon. The default value is null.

declaredClassStringreadonly

The name of the class. The declared class name is formatted as esri.folder.className.

extentExtentreadonly

The extent of the geometry. For points, the extent is null.

hasMBoolean

Indicates if the geometry has M values.

hasZBoolean

Indicates if the geometry has Z (elevation) values.

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

latitudeNumber

The latitude of the point if the spatial reference is Web Mercator (wkid: 3857) or WGS84 (wkid: 4326).

longitudeNumber

The longitude of the point if the spatial reference is Web Mercator (wkid: 3857) or WGS84 (wkid: 4326).

mNumber

The m-coordinate of the point in map units.

spatialReferenceSpatialReference autocast

The spatial reference of the geometry.

Default Value: WGS84 (wkid: 4326)

typeStringreadonly

For Point, the type is always point.

xNumber

The x-coordinate (easting) of the point in map units.

Default Value: 0

yNumber

The y-coordinate (northing) of the point in map units.

Default Value: 0

zNumber

The z-coordinate (or elevation) of the point in map units.

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

Method Overview

Method Details

clone(){Point}

Creates a deep clone of Point object.

Returns:

Type	Description
Point	A new instance of a Point object equal to the object used to call .clone().

copy(other)

Copies all values from another Point instance.

Parameter:

other Point The point to copy from.

distance(other){Number}

Computes the Euclidean distance between this Point and a given Point. Points must have the same spatial reference.

Parameter:

other Point The point to compute the distance to.

Returns:

Type	Description
Number	Returns the Euclidean distance between this Point and the other Point.

equals(point){Boolean}

Determines if the input point is equal to the point calling the function.

Parameter:

point Point The input point to test.

Returns:

Type	Description
Boolean	Returns true if the X, Y, Z coordinates of the input point along with its spatial reference and M value are exactly equal to those of the point calling equals().

fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter:

json Object A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns:

Type	Description
*	Returns a new instance of this class.

normalize(){Point}

Modifies the point geometry in-place by shifting the X-coordinate to within +/- 180 span in map units. You should clone the point object before calling this method where appropriate.

Returns:

Type	Description
Point	Returns a point with a normalized x-value.

toJSON(){Object}inherited

Converts an instance of this class to its ArcGIS Portal JSON representation. See the Using fromJSON() topic in the Guide for more information.

Returns:

Type	Description
Object	The ArcGIS Portal JSON representation of an instance of this class.
