Maps

Map class

google.maps.Map class

This class extends MVCObject.

Constructor
`Map`	`Map(mapDiv[, opts])` Parameters: `mapDiv`: `HTMLElement` 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<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: `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. For vector maps, this method sets the map's tilt and heading to their default zero values.
`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.
`getDiv`	`getDiv()` Parameters: None Return Value: `HTMLElement` The mapDiv of the map.
`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`.
`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.
`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`	Notice: Available only in the v=beta channel. `moveCamera(cameraOptions)` Parameters: `cameraOptions`: `CameraOptions` Return Value: None Immediately sets the map's camera to the target camera options, without animation.
`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}`. For both raster and vector maps, the map's zoom, tilt, and heading will not be changed.
`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 map measured in degrees from cardinal direction North. For raster maps, this method only applies to aerial imagery.
`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 For vector maps, sets the angle of incidence of the map. The allowed values are restricted depending on the zoom level of the map. 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.
`setZoom`	`setZoom(zoom)` Parameters: `zoom`: `number` Larger zoom values correspond to a higher resolution. Return Value: None Sets the zoom of the map.
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.
`isFractionalZoomEnabled optional`	Notice: Available only in the v=beta channel. Type: `boolean optional` Whether the map should allow fractional zoom levels. If not explicitly set to `true` or `false`, by default vector maps will allow fractional zoom and raster maps will not. Listen to `isfractionalzoomenabled_changed` to know when the default has been set.
`keyboardShortcuts optional`	Type: `boolean optional` If `false`, prevents the map from being controlled by the keyboard. Keyboard shortcuts are enabled by default.
`mapId optional`	Type: `string optional` The Map ID of the map. This parameter cannot be set or changed after a map is instantiated.

`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 zoom values are numbers from zero 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 zoom values are numbers from zero 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.

`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` For vector maps, sets the angle of incidence of the map. The allowed values are restricted depending on the zoom level of the map. For raster maps, 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 zoom values are numbers from zero up to the supported maximum zoom level. Larger zoom values correspond to a higher resolution.
`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.

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.

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 available map types within controls, for example.

Methods
`set`	`set(id, mapType)` Parameters: `id`: `string` Identifier of the MapType to add to the registry. `mapType`: `MapType\|` MapType object to add to the registry. 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.
