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

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.

Since: ArcGIS API for JavaScript 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.

hasM Booleanreadonly

Indicates if the geometry has M values.
Mvalues (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 zvalues (elevation).
Zvalues 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 mcoordinate of the point in map units.
Mvalues (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 xcoordinate (easting) of the point in map units.
 Default Value:0

y Number

The ycoordinate (northing) of the point in map units.
 Default Value:0

z Number

The zcoordinate (or elevation) of the point in map units.
Zvalues 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

addHandles(handleOrHandles, groupKey)inheritedSince: ArcGIS API for JavaScript 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 } ); // Handle gets removed when the object is destroyed. this.addHandles(handle);
ParametershandleOrHandles WatchHandleWatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey 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(){Point}

Creates a deep clone of Point object.
ReturnsType 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.
Parameterother PointThe 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.
Parameterother PointThe point to compute the distance to.
ReturnsType 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.
Parameterpoint PointThe input point to test.
ReturnsType 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 callingequals()
.

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.Parameterjson ObjectA 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.
ReturnsType Description * Returns a new instance of this class.

Since: ArcGIS API for JavaScript 4.25

Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns true
if a named group of handles exist.Example// Remove a named group of handles if they exist. if (obj.hasHandles("watchviewupdates")) { obj.removeHandles("watchviewupdates"); }

normalize(){Point}

Modifies the point geometry inplace by shifting the Xcoordinate to within +/ 180 span in map units. You should clone the point object before calling this method where appropriate.
ReturnsType Description Point Returns a point with a normalized xvalue.

removeHandles(groupKey)inheritedSince: ArcGIS API for JavaScript 4.25

Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handlegroup"); obj.removeHandles("otherhandlegroup");

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.
ReturnsType Description Object The ArcGIS portal JSON representation of an instance of this class.
