MapElement class

google.maps.MapElement class

MapElement is an HTMLElement subclass for rendering maps. After loading the maps library, a map can be created in HTML. For example:

<gmp-map center="37.4220656,-122.0840897" zoom="10" map-id="DEMO_MAP_ID">
  <button slot="control-block-start-inline-end">Custom Control</button>
</gmp-map>

Internally, it uses

Map

, which can be accessed with the

MapElement.innerMap

property.

Custom element:
<gmp-map center="lat,lng" heading-interaction-disabled internal-usage-attribution-ids="id1 id2" map-id="string" rendering-type="vector" tilt-interaction-disabled zoom="number"></gmp-map>

This class extends HTMLElement.

This class implements MapElementOptions.

Access by calling const {MapElement} = await google.maps.importLibrary("maps").
See Libraries in the Maps JavaScript API.

Properties center Type:  LatLng|LatLngLiteral optional

The center latitude/longitude of the map.

HTML attribute: headingInteractionDisabled

Type:  boolean optional

Default: false

Whether the map should allow user control of the camera heading (rotation). This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

HTML attribute: innerMap Type:  Map

A reference to the

Map

that the MapElement uses internally.

internalUsageAttributionIds Type:  Iterable<string> optional

Default: null

Adds a usage attribution ID to the initializer, which helps Google understand which libraries and samples are helpful to developers, such as usage of a marker clustering library. To opt out of sending the usage attribution ID, it is safe to delete this property or replace the value with an empty string. Only unique values will be sent. Changes to this value after instantiation may be ignored.

HTML attribute: mapId

Type:  string optional

The

map ID

of the map. This parameter cannot be set or changed after a map is instantiated.

Map.DEMO_MAP_ID

can be used to try out features that require a map ID but which do not require cloud enablement.

HTML attribute: renderingType Type:  RenderingType optional Default: RenderingType.VECTOR

Whether the map should be a raster or vector map. This parameter cannot be set or changed after a map is instantiated. If not set, then the cloud configuration for the map ID will determine the rendering type (if available). Please note that vector maps may not be available for all devices and browsers and the map will fall back to a raster map as needed.

HTML attribute: tiltInteractionDisabled

Type:  boolean optional

Default: false

Whether the map should allow user control of the camera tilt. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

HTML attribute: zoom

Type:  number optional

The zoom level of the map. Valid zoom values are numbers from zero up to the supported

maximum zoom level

. Larger zoom values correspond to a higher resolution.

HTML attribute: Methods addEventListener

Notice: Available only in the v=beta channel.

addEventListener(type, listener[, options])

Parameters: 

Return Value:  void

Sets up a function that will be called whenever the specified event is delivered to the target. See

addEventListener

.

removeEventListener

Notice: Available only in the v=beta channel.

removeEventListener(type, listener[, options])

Parameters: 

Return Value:  void

Removes an event listener previously registered with addEventListener from the target. See

removeEventListener

.

MapElementOptions interface

google.maps.MapElementOptions interface

Notice: Available only in the v=beta channel.

MapElementOptions object used to define the properties that can be set on a MapElement.

ZoomChangeEvent class

google.maps.ZoomChangeEvent class

This event is created from monitoring zoom change.

This class extends Event.

Access by calling const {ZoomChangeEvent} = await google.maps.importLibrary("maps").
See Libraries in the Maps JavaScript API.

Map class

google.maps.Map class

This class extends MVCObject.

Access by calling const {Map} = await google.maps.importLibrary("maps").
See Libraries in the Maps JavaScript API.

Constructor Map

Map(mapDiv[, opts])

Parameters: 

Creates a new map inside of the given HTML container, which is typically a DIV element.

Constants DEMO_MAP_ID Map ID which can be used for code samples which require a map ID. This map ID is not intended for use in production applications and cannot be used for features which require cloud configuration (such as Cloud Styling). Properties controls Type:  Array<MVCArray<HTMLElement>>

Additional controls to attach to the map. To add a control to the map, add the control's <div> to the MVCArray corresponding to the ControlPosition where it should be rendered.

data Type:  Data

An instance of Data, bound to the map. Add features to this Data object to conveniently display them on this map.

mapTypes Type:  MapTypeRegistry

A registry of MapType instances by string ID.

overlayMapTypes Type:  MVCArray<MapType optional>

Additional map types to overlay. Overlay map types will display on top of the base map they are attached to, in the order in which they appear in the overlayMapTypes array (overlays with higher index values are displayed in front of overlays with lower index values).

Methods fitBounds

fitBounds(bounds[, padding])

Parameters: 

Return Value:  None

Sets the viewport to contain the given bounds.
Note: When the map is set to display: none, the fitBounds function reads the map's size as 0x0, and therefore does not do anything. To change the viewport while the map is hidden, set the map to visibility: hidden, thereby ensuring the map div has an actual size. For vector maps, this method sets the map's tilt and heading to their default zero values. Calling this method may cause a smooth animation as the map pans and zooms to fit the bounds. Whether or not this method animates depends on an internal heuristic.

getBounds

getBounds()

Parameters:  None

Return Value:  LatLngBounds|undefined

The lat/lng bounds of the current viewport.

Returns the lat/lng bounds of the current viewport. If more than one copy of the world is visible, the bounds range in longitude from -180 to 180 degrees inclusive. If the map is not yet initialized or center and zoom have not been set then the result is

undefined

. For vector maps with non-zero tilt or heading, the returned lat/lng bounds represents the smallest bounding box that includes the visible region of the map's viewport. See

MapCanvasProjection.getVisibleRegion

for getting the exact visible region of the map's viewport.

getCenter

getCenter()

Parameters:  None

Return Value:  LatLng|undefined

Returns the position displayed at the center of the map. Note that this

LatLng

object is

not

wrapped. See

LatLng

for more information. If the center or bounds have not been set then the result is

undefined

.

getClickableIcons

getClickableIcons()

Parameters:  None

Return Value:  boolean|undefined

Returns the clickability of the map icons. A map icon represents a point of interest, also known as a POI. If the returned value is true, then the icons are clickable on the map.

getDatasetFeatureLayer

Notice: Available only in the v=beta channel.

getDatasetFeatureLayer(datasetId)

Parameters:  Return Value:  FeatureLayer

Returns the FeatureLayer for the specified datasetId. Dataset IDs must be configured in the Google Cloud Console. If the dataset ID is not associated with the map's map style, or if Data-driven styling is not available (no map ID, no vector tiles, no Data-Driven Styling feature layers or Datasets configured in the Map Style), this logs an error, and the resulting FeatureLayer.isAvailable will be false.

getDiv

getDiv()

Parameters:  None

Return Value:  HTMLElement

The mapDiv of the map.

getFeatureLayer

getFeatureLayer(featureType)

Parameters:  Return Value:  FeatureLayer

Returns the FeatureLayer of the specific FeatureType. A FeatureLayer must be enabled in the Google Cloud Console. If a FeatureLayer of the specified FeatureType does not exist on this map, or if Data-driven styling is not available (no map ID, no vector tiles, and no FeatureLayer enabled in the map style), this logs an error, and the resulting FeatureLayer.isAvailable will be false.

getHeading

getHeading()

Parameters:  None

Return Value:  number|undefined

Returns the compass heading of the map. The heading value is measured in degrees (clockwise) from cardinal direction North. If the map is not yet initialized then the result is undefined.

getHeadingInteractionEnabled

getHeadingInteractionEnabled()

Parameters:  None

Return Value:  boolean|null

Returns whether heading interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

getInternalUsageAttributionIds

getInternalUsageAttributionIds()

Parameters:  None

Return Value:  Iterable<string>|null

Returns the list of usage attribution IDs, which help Google understand which libraries and samples are helpful to developers, such as usage of a marker clustering library.

getMapCapabilities

getMapCapabilities()

Parameters:  None

Return Value:  MapCapabilities

Informs the caller of the current capabilities available to the map based on the map ID that was provided.

getMapTypeId

getMapTypeId()

Parameters:  None

Return Value:  MapTypeId|string|undefined getProjection

getProjection()

Parameters:  None

Return Value:  Projection|undefined

Returns the current Projection. If the map is not yet initialized then the result is undefined. Listen to the projection_changed event and check its value to ensure it is not undefined.

getRenderingType

getRenderingType()

Parameters:  None

Return Value:  RenderingType

Returns the current RenderingType of the map.

getStreetView

getStreetView()

Parameters:  None

Return Value:  StreetViewPanorama

The panorama bound to the map.

Returns the default StreetViewPanorama bound to the map, which may be a default panorama embedded within the map, or the panorama set using setStreetView(). Changes to the map's streetViewControl will be reflected in the display of such a bound panorama.

getTilt

getTilt()

Parameters:  None

Return Value:  number|undefined

Returns the current angle of incidence of the map, in degrees from the viewport plane to the map plane. For raster maps, the result will be 0 for imagery taken directly overhead or 45 for 45° imagery. This method does not return the value set by setTilt. See setTilt for details.

getTiltInteractionEnabled

getTiltInteractionEnabled()

Parameters:  None

Return Value:  boolean|null

Returns whether tilt interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

getZoom

getZoom()

Parameters:  None

Return Value:  number|undefined

Returns the zoom of the map. If the zoom has not been set then the result is undefined.

moveCamera

moveCamera(cameraOptions)

Parameters: 

Return Value:  None

Immediately sets the map's camera to the target camera options, without animation.

panBy

panBy(x, y)

Parameters: 

Return Value:  None

Changes the center of the map by the given distance in pixels. If the distance is less than both the width and height of the map, the transition will be smoothly animated. Note that the map coordinate system increases from west to east (for x values) and north to south (for y values).

panTo

panTo(latLng)

Parameters: 

Return Value:  None

Changes the center of the map to the given LatLng. If the change is less than both the width and height of the map, the transition will be smoothly animated.

panToBounds

panToBounds(latLngBounds[, padding])

Parameters: 

Return Value:  None

Pans the map by the minimum amount necessary to contain the given LatLngBounds. It makes no guarantee where on the map the bounds will be, except that the map will be panned to show as much of the bounds as possible inside {currentMapSizeInPx} - {padding}. For both raster and vector maps, the map's zoom, tilt, and heading will not be changed.

setCenter

setCenter(latlng)

Parameters: 

Return Value:  None

setClickableIcons

setClickableIcons(value)

Parameters: 

Return Value:  None

Controls whether the map icons are clickable or not. A map icon represents a point of interest, also known as a POI. To disable the clickability of map icons, pass a value of false to this method.

setHeading

setHeading(heading)

Parameters: 

Return Value:  None

Sets the compass heading for map measured in degrees from cardinal direction North. For raster maps, this method only applies to aerial imagery.

setHeadingInteractionEnabled

setHeadingInteractionEnabled(headingInteractionEnabled)

Parameters: 

Return Value:  None

Sets whether heading interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

setMapTypeId

setMapTypeId(mapTypeId)

Parameters: 

Return Value:  None

setOptions

setOptions(options)

Parameters: 

Return Value:  None

setRenderingType

setRenderingType(renderingType)

Parameters: 

Return Value:  None

Sets the current RenderingType of the map.

setStreetView

setStreetView(panorama)

Parameters: 

Return Value:  None

Binds a StreetViewPanorama to the map. This panorama overrides the default StreetViewPanorama, allowing the map to bind to an external panorama outside of the map. Setting the panorama to null binds the default embedded panorama back to the map.

setTilt

setTilt(tilt)

Parameters: 

Return Value:  None

For raster maps, controls the automatic switching behavior for the angle of incidence of the map. The only allowed values are 0 and 45. setTilt(0) causes the map to always use a 0° overhead view regardless of the zoom level and viewport. setTilt(45) causes the tilt angle to automatically switch to 45 whenever 45° imagery is available for the current zoom level and viewport, and switch back to 0 whenever 45° imagery is not available (this is the default behavior). 45° imagery is only available for satellite and hybrid map types, within some locations, and at some zoom levels. Note: getTilt returns the current tilt angle, not the value set by setTilt. Because getTilt and setTilt refer to different things, do not bind() the tilt property; doing so may yield unpredictable effects.

setTiltInteractionEnabled

setTiltInteractionEnabled(tiltInteractionEnabled)

Parameters: 

Return Value:  None

Sets whether tilt interactions are enabled. This option is only in effect when the map is a vector map. If not set in code, then the cloud configuration for the map ID will be used (if available).

setZoom

setZoom(zoom)

Parameters: 

Return Value:  None

Sets the zoom of the map.

Properties stylers Type:  Array<Object>

The style rules to apply to the selected map features and elements. The rules are applied in the order that you specify in this array. For guidelines on usage and allowed values, see the

style reference

.

elementType optional

Type:  string optional

The element to which a styler should be applied. An element is a visual aspect of a feature on the map. Example: a label, an icon, the stroke or fill applied to the geometry, and more. Optional. If

elementType

is not specified, the value is assumed to be

'all'

. For details of usage and allowed values, see the

style reference

.

featureType optional

Type:  string optional

The feature, or group of features, to which a styler should be applied. Optional. If

featureType

MapMouseEvent interface

google.maps.MapMouseEvent interface

This object is returned from various mouse events on the map and overlays, and contains all the fields shown below.

Properties domEvent Type:  MouseEvent|TouchEvent|PointerEvent|KeyboardEvent|Event

The corresponding native DOM event. Developers should not rely on

target

,

currentTarget

,

relatedTarget

and

path

properties being defined and consistent. Developers should not also rely on the DOM structure of the internal implementation of the Maps API. Due to internal event mapping, the

domEvent

may have different semantics from the

MapMouseEvent

(e.g. a

MapMouseEvent

"click" may have a

domEvent

of type

KeyboardEvent

).

latLng optional Type:  LatLng optional

The latitude/longitude that was below the cursor when the event occurred.

Methods stop

stop()

Parameters:  None

Return Value:  void

Prevents this event from propagating further.

IconMouseEvent interface

google.maps.IconMouseEvent interface

This object is sent in an event when a user clicks on an icon on the map. The place ID of this place is stored in the placeId member. To prevent the default info window from showing up, call the stop() method on this event to prevent it being propagated. Learn more about place IDs in the Places API developer guide.

This interface extends MapMouseEvent.

When set, a user can only pan and zoom inside the given bounds. Bounds can restrict both longitude and latitude, or can restrict latitude only. For latitude-only bounds use west and east longitudes of -180 and 180, respectively, for example, latLngBounds: {north: northLat, south: southLat, west: -180, east: 180}.

strictBounds optional

Type:  boolean optional

Bounds can be made more restrictive by setting the strictBounds flag to true. This reduces how far a user can zoom out, ensuring that everything outside of the restricted bounds stays hidden. The default is false, meaning that a user can zoom out until the entire bounded area is in view, possibly including areas outside the bounded area.

TrafficLayerOptions interface

google.maps.TrafficLayerOptions interface

TrafficLayerOptions object used to define the properties that can be set on a TrafficLayer.

Properties autoRefresh optional

Type:  boolean optional

Default: true

Whether the traffic layer refreshes with updated information automatically.

map optional Type:  Map optional

Map on which to display the traffic layer.

BicyclingLayer class

google.maps.BicyclingLayer class

A layer showing bike lanes and paths.

This class extends MVCObject.

Access by calling const {BicyclingLayer} = await google.maps.importLibrary("maps").
See Libraries in the Maps JavaScript API.

Constructor BicyclingLayer

BicyclingLayer()

Parameters:  None

A layer that displays bike lanes and paths and demotes large roads.

CameraOptions interface

google.maps.CameraOptions interface

Notice: Available only in the v=beta channel.

Used for setting the map's camera options.

VisibleRegion interface

google.maps.VisibleRegion interface

Contains the four points defining the four-sided polygon that is the visible region of the map. On a vector map this polygon can be a trapezoid instead of a rectangle, when a vector map has tilt.

RenderingType constants

google.maps.RenderingType constants

Access by calling const {RenderingType} = await google.maps.importLibrary("maps").
See Libraries in the Maps JavaScript API.

Constants RASTER Indicates that the map is a raster map. UNINITIALIZED Indicates that it is unknown yet whether the map is vector or raster, because the map has not finished initializing yet. VECTOR Indicates that the map is a vector map. MapCapabilities interface

google.maps.MapCapabilities interface

Object containing a snapshot of what capabilities are currently available for the Map. Note that this does not necessarily mean that relevant modules are loaded or initialized, but rather that the current map has permission to use these APIs. See the properties for a list of possible capabilities.
