Point | API Reference | ArcGIS Maps SDK for JavaScript 4.33

ESM: import Point from "@arcgis/core/geometry/Point.js";

CDN: const Point = await $arcgis.import("@arcgis/core/geometry/Point.js");

Class: @arcgis/core/geometry/Point

Since: ArcGIS Maps SDK 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.

Point Constructor new Point(properties)

Parameter

optional

See the properties for a list of all the properties that may be passed into the constructor.

cache

Inherited

Property cache Objectreadonly

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

declaredClass

Inherited

Property declaredClass Stringreadonly

Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

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

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.

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.

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.

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.

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.

The spatial reference of the geometry.

Default Value:SpatialReference.WGS84 // wkid: 4326

type Property type Stringreadonly

The string value representing the type of geometry.

For Point the type is always "point".

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

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

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.

addHandles

Inherited

Method addHandles(handleOrHandles, groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

clone Method 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 Method copy(other){this}

Copies all values from another Point instance.

Returns

Type Description this Returns this instance.

distance Method distance(other){Number}

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

Parameter

The point to compute the distance to.

Returns

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

equals Method equals(point){Boolean}

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

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

Inherited

Method fromJSON(json){* |null |undefined}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.

Returns

Type Description * | null | undefined Returns a new instance of this class.

hasHandles

Inherited

Method hasHandles(groupKey){Boolean}

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter

groupKey *

optional

A group key.

Returns

Type Description Boolean Returns true if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

normalize Method 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.

removeHandles

Inherited

Method removeHandles(groupKey)

Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 4.25.

Removes a group of handles owned by the object.

Parameter

groupKey *

optional

A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
