Map3DElement is an HTML interface for the 3D Map view.

Custom element:
<gmp-map-3d center="lat,lng,altitude" default-labels-disabled default-ui-disabled heading="number" max-altitude="number" max-heading="number" max-tilt="number" min-altitude="number" min-heading="number" min-tilt="number" range="number" roll="number" tilt="number"></gmp-map-3d>

This class extends HTMLElement.

This class implements Map3DElementOptions.

Access by calling const {Map3DElement} = await google.maps.importLibrary("maps3d"). See Libraries in the Maps JavaScript API.
Map3DElement
Map3DElement([options])
Parameters: 
bounds
When set, restricts the position of the camera within the specified lat/lng bounds. Note that objects outside the bounds are still rendered. Bounds can restrict both longitude and latitude, or can restrict either latitude or longitude only. For latitude-only bounds use west and east longitudes of -180 and 180, respectively. For longitude-only bounds use north and south latitudes of 90 and -90, respectively.
center
The center of the map given as a LatLngAltitude, where altitude is in meters above ground level. Note that this is not necessarily where the camera is located, as the range field affects the camera's distance from the map center. If not set, defaults to {lat: 0, lng: 0, altitude: 63170000}. 63170000 meters is a maximum allowed altitude (Earth radius multiplied by 10).
HTML attribute:
  • <gmp-map-3d center="lat,lng,altitude"></gmp-map-3d>
defaultLabelsDisabled
Type:  boolean optional
Default: false
When true, default map labels aren't rendered.

maxHeading
Type:  number optional
The maximum angle of heading (rotation) of the map. A valid value is between 0 and 360 degrees. minHeading and maxHeading represent an interval of <= 360 degrees in which heading gestures will be allowed. minHeading = 180 and maxHeading = 90 will allow heading in [0, 90] and heading in [180, 360]. minHeading = 90 and maxHeading = 180 will allow heading in [90, 180].
HTML attribute:

BetaaddEventListener
addEventListener(type, listener[, options])
Parameters: 
  • type:  string A case-sensitive string representing the event type to listen for.
  • listener:  EventListener|EventListenerObject The object that receives a notification. This must be a function or an object with the handleEvent method
  • options:  boolean|AddEventListenerOptions optional See options. Custom events only support capture and passive.
Return Value:  void
Sets up a function that will be called whenever the specified event is delivered to the target. See addEventListener
flyCameraAround
flyCameraAround(options)
Parameters: 
Return Value:  None
This method orbits the camera around a given location for a given duration, making the given number of rounds in that time.

By default, the camera orbits clockwise. If given a negative number for rounds, the camera will orbit in a counter-clockwise direction instead.

The method is asynchronous because animations can only start after the map has loaded a minimum amount. The method returns once the animation has been started.

If the number of rounds is zero, no spin will occur, and the animation will complete immediately after it starts.
flyCameraTo
flyCameraTo(options)
Parameters: 
Return Value:  None
This method moves the camera parabolically from the current location to a given end location over a given duration.

The method is asynchronous because animations can only start after the map has loaded a minimum amount. The method returns once the animation has been started.
BetaremoveEventListener
removeEventListener(type, listener[, options])
Parameters: 
Return Value:  void
Removes an event listener previously registered with addEventListener from the target. See removeEventListener
stopCameraAnimation
stopCameraAnimation()
Parameters:  None
Return Value:  None
This method stops any fly animation that might happen to be running. The camera stays wherever it is mid-animation; it does not teleport to the end point.

The method is asynchronous because animations can only start or stop after the map has loaded a minimum amount. The method returns once the animation has stopped.
gmp-animationend

Type:  boolean optional
Default: false
Specifies whether to connect the polygon to the ground. To extrude a polygon, the altitudeMode must be either RELATIVE_TO_GROUND or ABSOLUTE.
HTML attribute:
  • <gmp-polygon-3d extruded></gmp-polygon-3d>
fillColor
Type:  string optional
The fill color. All CSS3 colors are supported.
HTML attribute:
  • <gmp-polygon-3d fill-color="string"></gmp-polygon-3d>
geodesic
Type:  boolean optional
Default: false
When true, edges of the polygon are interpreted as geodesic and will follow the curvature of the Earth. When false, edges of the polygon are rendered as straight lines in screen space.
HTML attribute:
  • <gmp-polygon-3d geodesic></gmp-polygon-3d>
innerCoordinates
The ordered sequence of coordinates that designates a closed loop. Unlike polylines, a polygon may consist of one or more paths, which create multiple cut-outs inside the polygon.
outerCoordinates
The ordered sequence of coordinates that designates a closed loop. Altitude is ignored in certain modes and thus optional.
strokeColor
Type:  string optional
The stroke color. All CSS3 colors are supported.
HTML attribute:
  • <gmp-polygon-3d stroke-color="string"></gmp-polygon-3d>
strokeWidth
Type:  number optional
The stroke width in pixels.
HTML attribute:
  • <gmp-polygon-3d stroke-width="number"></gmp-polygon-3d>
zIndex
Type:  number optional
The zIndex compared to other polys.
HTML attribute:
  • <gmp-polygon-3d z-index="number"></gmp-polygon-3d>
BetaaddEventListener
addEventListener(type, listener[, options])
Parameters: 
  • type:  string A case-sensitive string representing the event type to listen for.
  • listener:  EventListener|EventListenerObject The object that receives a notification. This must be a function or an object with the handleEvent method
  • options:  boolean|AddEventListenerOptions optional See options. Custom events only support capture and passive.
Return Value:  void
Sets up a function that will be called whenever the specified event is delivered to the target. See addEventListener
BetaremoveEventListener
removeEventListener(type, listener[, options])
Parameters: 
Return Value:  void
Removes an event listener previously registered with addEventListener from the target. See removeEventListener

AltitudeMode constants

google.maps.maps3d.AltitudeMode constants

Specifies how altitude components in the coordinates are interpreted.

Access by calling const {AltitudeMode} = await google.maps.importLibrary("maps3d"). See Libraries in the Maps JavaScript API.
ABSOLUTE Allows to express objects relative to the average mean sea level. That also means that if the terrain level of detail changes underneath the object, its absolute position will remain the same.
CLAMP_TO_GROUND Allows to express objects placed on the ground. They will remain at ground level following the terrain regardless of what altitude is provided. If the object is positioned over a major body of water, it will be placed at sea level.
RELATIVE_TO_GROUND Allows to express objects relative to the ground surface. If the terrain level of detail changes, the position of the object will remain constant relative to the ground. When over water, the altitude will be interpreted as a value in meters above sea level.
RELATIVE_TO_MESH Allows to express objects relative to the highest of ground+building+water surface. When over water, this will be water surface; when over terrain, this will be the building surface (if present) or ground surface (if no buildings).
