Maps

Map class

google.maps.Map class

This class extends MVCObject.

Constructor
Map	Map(mapDiv[, opts]) Parameters:  mapDiv:  Element The map will render to fill this element. opts:  MapOptions optional Options Creates a new map inside of the given HTML container, which is typically a DIV element.

Properties
controls	Type:  Array<MVCArray<Node>> 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:  bounds:  LatLngBounds|LatLngBoundsLiteral Bounds to show. padding:  number|Padding optional Padding in pixels. The bounds will be fit in the part of the map that remains after padding is removed. A number value will yield the same padding on all 4 sides. Supply 0 here to make a fitBounds idempotent on the result of getBounds. 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.
getBounds	getBounds() Parameters:  None Return Value:  LatLngBounds optional 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.
getCenter	getCenter() Parameters:  None Return Value:  LatLng optional 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 optional 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.
getDiv	getDiv() Parameters:  None Return Value:  Element The mapDiv of the map.
getHeading	getHeading() Parameters:  None Return Value:  number optional Returns the compass heading of aerial imagery. The heading value is measured in degrees (clockwise) from cardinal direction North. If the map is not yet initialized then the result is undefined.
getMapTypeId	getMapTypeId() Parameters:  None Return Value:  MapTypeId|string optional
getProjection	getProjection() Parameters:  None Return Value:  Projection optional 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.
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 optional Returns the current angle of incidence of the map, in degrees from the viewport plane to the map plane. The result will be 0 for imagery taken directly overhead or 45 for 45° imagery. 45° imagery is only available for satellite and hybrid map types, within some locations, and at some zoom levels. Note: This method does not return the value set by setTilt. See setTilt for details.
getZoom	getZoom() Parameters:  None Return Value:  number optional Returns the zoom of the map. If the zoom has not been set then the result is undefined.
panBy	panBy(x, y) Parameters:  x:  number Number of pixels to move the map in the x direction. y:  number Number of pixels to move the map in the y direction. 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:  latLng:  LatLng|LatLngLiteral The new center latitude/longitude of the map. 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:  latLngBounds:  LatLngBounds|LatLngBoundsLiteral The bounds to pan the map to. padding:  number|Padding optional Padding in pixels. A number value will yield the same padding on all 4 sides. The default value is 0. 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}.
setCenter	setCenter(latlng) Parameters:  latlng:  LatLng|LatLngLiteral Return Value:  None
setClickableIcons	setClickableIcons(value) Parameters:  value:  boolean 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:  heading:  number Return Value:  None Sets the compass heading for aerial imagery measured in degrees from cardinal direction North.
setMapTypeId	setMapTypeId(mapTypeId) Parameters:  mapTypeId:  MapTypeId|string Return Value:  None
setOptions	setOptions(options) Parameters:  options:  MapOptions optional Return Value:  None
setStreetView	setStreetView(panorama) Parameters:  panorama:  StreetViewPanorama The panorama to bind to the map. 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:  tilt:  number Return Value:  None 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.
setZoom	setZoom(zoom) Parameters:  zoom:  number Return Value:  None
Inherited: addListener, bindTo, get, notify, set, setValues, unbind, unbindAll

MapOptions interface

google.maps.MapOptions interface

MapOptions object used to define the properties that can be set on a Map.

Properties
backgroundColor optional	Type:  string optional Color used for the background of the Map div. This color will be visible when tiles have not yet loaded as the user pans. This option can only be set when the map is initialized.
center optional	Type:  LatLng|LatLngLiteral optional The initial Map center.
clickableIcons optional	Type:  boolean optional When false, map icons are not clickable. A map icon represents a point of interest, also known as a POI. By default map icons are clickable.
controlSize optional	Type:  number optional Size in pixels of the controls appearing on the map. This value must be supplied directly when creating the Map, updating this value later may bring the controls into an undefined state. Only governs the controls made by the Maps API itself. Does not scale developer created custom controls.
disableDefaultUI optional	Type:  boolean optional Enables/disables all default UI buttons. May be overridden individually. Does not disable the keyboard controls, which are separately controlled by the MapOptions.keyboardShortcuts option. Does not disable gesture controls, which are separately controlled by the MapOptions.gestureHandling option.
disableDoubleClickZoom optional	Type:  boolean optional Enables/disables zoom and center on double click. Enabled by default. Note: This property is not recommended. To disable zooming on double click, you can use the gestureHandling property, and set it to "none".
draggable optional	Notice: Deprecated in 2017. To disable dragging on the map, you can use the gestureHandling property, and set it to "none". Type:  boolean optional If false, prevents the map from being dragged. Dragging is enabled by default.
draggableCursor optional	Type:  string optional The name or url of the cursor to display when mousing over a draggable map. This property uses the css cursor attribute to change the icon. As with the css property, you must specify at least one fallback cursor that is not a URL. For example: draggableCursor: 'url(http://www.example.com/icon.png), auto;'.
draggingCursor optional	Type:  string optional The name or url of the cursor to display when the map is being dragged. This property uses the css cursor attribute to change the icon. As with the css property, you must specify at least one fallback cursor that is not a URL. For example: draggingCursor: 'url(http://www.example.com/icon.png), auto;'.
fullscreenControl optional	Type:  boolean optional The enabled/disabled state of the Fullscreen control.
fullscreenControlOptions optional	Type:  FullscreenControlOptions optional The display options for the Fullscreen control.
gestureHandling optional	Type:  string optional This setting controls how the API handles gestures on the map. Allowed values: "cooperative": Scroll events and one-finger touch gestures scroll the page, and do not zoom or pan the map. Two-finger touch gestures pan and zoom the map. Scroll events with a ctrl key or ⌘ key pressed zoom the map. In this mode the map cooperates with the page. "greedy": All touch gestures and scroll events pan or zoom the map. "none": The map cannot be panned or zoomed by user gestures. "auto": (default) Gesture handling is either cooperative or greedy, depending on whether the page is scrollable or in an iframe.
heading optional	Type:  number optional The heading for aerial imagery in degrees measured clockwise from cardinal direction North. Headings are snapped to the nearest available angle for which imagery is available.
keyboardShortcuts optional	Type:  boolean optional If false, prevents the map from being controlled by the keyboard. Keyboard shortcuts are enabled by default.
mapTypeControl optional	Type:  boolean optional The initial enabled/disabled state of the Map type control.
mapTypeControlOptions optional	Type:  MapTypeControlOptions optional The initial display options for the Map type control.
mapTypeId optional	Type:  MapTypeId|string optional The initial Map mapTypeId. Defaults to ROADMAP.
maxZoom optional	Type:  number optional The maximum zoom level which will be displayed on the map. If omitted, or set to null, the maximum zoom from the current map type is used instead. Valid values: Integers between zero, and up to the supported maximum zoom level.
minZoom optional	Type:  number optional The minimum zoom level which will be displayed on the map. If omitted, or set to null, the minimum zoom from the current map type is used instead. Valid values: Integers between zero, and up to the supported maximum zoom level.
noClear optional	Type:  boolean optional If true, do not clear the contents of the Map div.
panControl optional	Type:  boolean optional The enabled/disabled state of the Pan control. Note: The Pan control is not available in the new set of controls introduced in v3.22 of the Google Maps JavaScript API. While using v3.22 and v3.23, you can choose to use the earlier set of controls rather than the new controls, thus making the Pan control available as part of the old control set. See What's New in the v3.22 Map Controls.
panControlOptions optional	Type:  PanControlOptions optional The display options for the Pan control. Note: The Pan control is not available in the new set of controls introduced in v3.22 of the Google Maps JavaScript API. While using v3.22 and v3.23, you can choose to use the earlier set of controls rather than the new controls, thus making the Pan control available as part of the old control set. See What's New in the v3.22 Map Controls.
restriction optional	Type:  MapRestriction optional Defines a boundary that restricts the area of the map accessible to users. When set, a user can only pan and zoom while the camera view stays inside the limits of the boundary.
rotateControl optional	Type:  boolean optional The enabled/disabled state of the Rotate control.
rotateControlOptions optional	Type:  RotateControlOptions optional The display options for the Rotate control.
scaleControl optional	Type:  boolean optional The initial enabled/disabled state of the Scale control.

scrollwheel optional	Type:  boolean optional If false, disables zooming on the map using a mouse scroll wheel. The scrollwheel is enabled by default. Note: This property is not recommended. To disable zooming using scrollwheel, you can use the gestureHandling property, and set it to either "cooperative" or "none".
streetView optional	Type:  StreetViewPanorama optional A StreetViewPanorama to display when the Street View pegman is dropped on the map. If no panorama is specified, a default StreetViewPanorama will be displayed in the map's div when the pegman is dropped.
streetViewControl optional	Type:  boolean optional The initial enabled/disabled state of the Street View Pegman control. This control is part of the default UI, and should be set to false when displaying a map type on which the Street View road overlay should not appear (e.g. a non-Earth map type).
streetViewControlOptions optional	Type:  StreetViewControlOptions optional The initial display options for the Street View Pegman control.
styles optional	Type:  Array<MapTypeStyle> optional Styles to apply to each of the default map types. Note that for satellite/hybrid and terrain modes, these styles will only apply to labels and geometry.
tilt optional	Type:  number optional Controls the automatic switching behavior for the angle of incidence of the map. The only allowed values are 0 and 45. The value 0 causes the map to always use a 0° overhead view regardless of the zoom level and viewport. The value 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 specified by this option. Because getTilt and this option refer to different things, do not bind() the tilt property; doing so may yield unpredictable effects.
zoom optional	Type:  number optional The initial Map zoom level. Valid values: Integers between zero, and up to the supported maximum zoom level.
zoomControl optional	Type:  boolean optional The enabled/disabled state of the Zoom control.
zoomControlOptions optional	Type:  ZoomControlOptions optional The display options for the Zoom control.

MapTypeStyle interface

google.maps.MapTypeStyle interface

The MapTypeStyle is a collection of selectors and stylers that define how the map should be styled. Selectors specify the map features and/or elements that should be affected, and stylers specify how those features and elements should be modified. For details, see the style reference.

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 is not specified, the value is assumed to be 'all'. For details of usage and allowed values, see the style reference.

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

Methods
stop	stop() Parameters:  None Return Value:  None 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.

Properties
placeId optional	Type:  string optional The place ID of the place that was clicked. This place ID can be used to query more information about the feature that was clicked. Learn more about place IDs in the Places API developer guide.
Inherited: domEvent, latLng

Methods
Inherited: stop

MapTypeId constants

google.maps.MapTypeId constants

Identifiers for common MapTypes. Specify these by value, or by using the constant's name. For example, 'satellite' or google.maps.MapTypeId.SATELLITE.

Constants
HYBRID	This map type displays a transparent layer of major streets on satellite images.
ROADMAP	This map type displays a normal street map.
SATELLITE	This map type displays satellite images.
TERRAIN	This map type displays maps with physical features such as terrain and vegetation.

MapTypeRegistry class

google.maps.MapTypeRegistry class

A registry for MapType instances, keyed by MapType id.

This class extends MVCObject.

Constructor
MapTypeRegistry	MapTypeRegistry() Parameters:  None The MapTypeRegistry holds the collection of custom map types available to the map for its use. The API consults this registry when providing the list of avaiable map types within controls, for example.

Methods
set	set(id, mapType) Parameters:  id:  string mapType:  MapType|* Return Value:  None Sets the registry to associate the passed string identifier with the passed MapType.
Inherited: addListener, bindTo, get, notify, setValues, unbind, unbindAll

MapRestriction interface

google.maps.MapRestriction interface

A restriction that can be applied to the Map. The map's viewport will not exceed these restrictions.

Properties
latLngBounds	Type:  LatLngBounds|LatLngBoundsLiteral 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.

TrafficLayer class

google.maps.TrafficLayer class
