Point

AMD: require(["esri/geometry/Point"], (Point) => { /* code goes here */ });
ESM: import Point from "@arcgis/core/geometry/Point";
Class: esri/geometry/Point
Inheritance: Point Geometry Accessor
Since: ArcGIS API for JavaScript 4.0

A location defined by X, Y, and Z coordinates.

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.

Property Details

cache Objectreadonly inherited

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.

declaredClass Stringreadonly inherited
Since: ArcGIS API for JavaScript 4.7

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

extent Extentreadonly inherited

The extent of the geometry. For a point, the extent is null.

hasM Booleanreadonly

Indicates if the geometry has M values.

M-values (measure) allow attribute values to be stored at the vertex of a point. A common usage for storing a measurement in the vertices along a linear feature are linear referencing applications.

hasZ Booleanreadonly

Indicates if the geometry has z-values (elevation).

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.

latitude Number

The latitude of the point. If the spatial reference is Web Mercator, the latitude will be given in WGS84. In any geographic spatial reference, the latitude will equal the y coordinate. In all other cases the latitude will be null.

longitude Number

The longitude of the point. If the spatial reference is Web Mercator, the longitude will be given in WGS84. In any geographic spatial reference, the longitude will equal the x coordinate. In all other cases the longitude will be null.

m Number

The m-coordinate of the point in map units.

M-values (measure) allow attribute values to be stored at the vertex of a point. A common usage for storing a measurement in the vertices along a linear feature are linear referencing applications.

Default Value:undefined

The spatial reference of the geometry.

Default Value:WGS84 (wkid: 4326)
type Stringreadonly

The string value representing the type of geometry.

For Point the type is always "point".

x Number

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

Default Value:0
y Number

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

Default Value:0
z Number

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.

Default Value:undefined

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 an ArcGIS product. 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() guide topic for more information.

Returns:
Type Description
Object The ArcGIS portal JSON representation of an instance of this class.
