Map class

google.maps.Map class

This class extends MVCObject.

Constructor
Map(mapDiv:Element, opts?:MapOptions) Creates a new map inside of the given HTML container, which is typically a DIV element.
Methods
fitBounds(bounds:LatLngBounds|LatLngBoundsLiteral)
Return Value:  None
Sets the viewport to contain the given bounds.
getBounds()
Return Value:  LatLngBounds
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 (i.e. the mapType is still null), or center and zoom have not been set then the result is null or undefined.
getCenter()
Return Value:  LatLng
Returns the position displayed at the center of the map. Note that this LatLng object is not wrapped. See LatLng for more information.
getClickableIcons()
Return Value:  boolean
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()
Return Value:  Element
getHeading()
Return Value:  number
Returns the compass heading of aerial imagery. The heading value is measured in degrees (clockwise) from cardinal direction North.
getMapTypeId()
Return Value:  MapTypeId|string
getProjection()
Return Value:  Projection
Returns the current Projection. If the map is not yet initialized (i.e. the mapType is still null) then the result is null. Listen to projection_changed and check its value to ensure it is not null.
getStreetView()
Return Value:  StreetViewPanorama
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()
Return Value:  number
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()
Return Value:  number
panBy(x:number, y:number)
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(latLng:LatLng|LatLngLiteral)
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(latLngBounds:LatLngBounds|LatLngBoundsLiteral)
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 as much of the bounds as possible will be visible. The bounds will be positioned inside the area bounded by the map type and navigation (pan, zoom, and Street View) controls, if they are present on the map. If the bounds is larger than the map, the map will be shifted to include the northwest corner of the bounds. If the change in the map's position is less than both the width and height of the map, the transition will be smoothly animated.
setCenter(latlng:LatLng|LatLngLiteral)
Return Value:  None
setClickableIcons(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(heading:number)
Return Value:  None
Sets the compass heading for aerial imagery measured in degrees from cardinal direction North.
setMapTypeId(mapTypeId:MapTypeId|string)
Return Value:  None
setOptions(options:MapOptions)
Return Value:  None
setStreetView(panorama:StreetViewPanorama)
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(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(zoom:number)
Return Value:  None
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.

panControl
Type:  boolean
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
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.

streetViewControlOptions
The initial display options for the Street View Pegman control.
styles
Type:  Array<MapTypeStyle>
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
Type:  number
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.

Data class

google.maps.Data class

A layer for displaying geospatial data. Points, line-strings and polygons can be displayed.

Every Map has a Data object by default, so most of the time there is no need to construct one. For example: 

 var myMap = new google.maps.Map(...);
 myMap.data.addGeoJson(...);
 myMap.data.setStyle(...);
The Data object is a collection of Features.

This class extends MVCObject.

Constructor
Data(options?:Data.DataOptions) Creates an empty collection, with the given DataOptions.
Methods
add(feature?:Data.Feature|Data.FeatureOptions)
Return Value:  Data.Feature
Adds a feature to the collection, and returns the added feature.

If the feature has an ID, it will replace any existing feature in the collection with the same ID. If no feature is given, a new feature will be created with null geometry and no properties. If FeatureOptions are given, a new feature will be created with the specified properties.

Note that the IDs 1234 and '1234' are equivalent. Adding a feature with ID 1234 will replace a feature with ID '1234', and vice versa.
addGeoJson(geoJson:Object, options?:Data.GeoJsonOptions)
Return Value:  Array<Data.Feature>
Adds GeoJSON features to the collection. Give this method a parsed JSON. The imported features are returned. Throws an exception if the GeoJSON could not be imported.
contains(feature:Data.Feature)
Return Value:  boolean
Checks whether the given feature is in the collection.
forEach(callback:function(Data.Feature))
Return Value:  None
Repeatedly invokes the given function, passing a feature in the collection to the function on each invocation. The order of iteration through the features is undefined.
getControlPosition()
Return Value:  ControlPosition
Returns the position of the drawing controls on the map.
getControls()
Return Value:  Array<string>
Returns which drawing modes are available for the user to select, in the order they are displayed. This does not include the null drawing mode, which is added by default. Possible drawing modes are "Point", "LineString" or "Polygon".
getDrawingMode()
Return Value:  string
Returns the current drawing mode of the given Data layer. A drawing mode of null means that the user can interact with the map as normal, and clicks do not draw anything. Possible drawing modes are null, "Point", "LineString" or "Polygon".
getFeatureById(id:number|string)
Return Value:  Data.Feature|undefined
Returns the feature with the given ID, if it exists in the collection. Otherwise returns undefined.

Note that the IDs 1234 and '1234' are equivalent. Either can be used to look up the same feature.
getMap()
Return Value:  Map
Returns the map on which the features are displayed.
getStyle()
Gets the style for all features in the collection.
loadGeoJson(url:string, options?:Data.GeoJsonOptions, callback?:function(Array<Data.Feature>))
Return Value:  None
Loads GeoJSON from a URL, and adds the features to the collection.

overrideStyle(feature:Data.Feature, style:Data.StyleOptions)
Return Value:  None
Changes the style of a feature. These changes are applied on top of the style specified by setStyle(). Style properties set to null revert to the value specified via setStyle().
remove(feature:Data.Feature)
Return Value:  None
Removes a feature from the collection.
revertStyle(feature?:Data.Feature)
Return Value:  None
Removes the effect of previous overrideStyle() calls. The style of the given feature reverts to the style specified by setStyle().

If no feature is given, all features have their style reverted.
setControlPosition(controlPosition:ControlPosition)
Return Value:  None
Sets the position of the drawing controls on the map.
setControls(controls:Array<string>)
Return Value:  None
Sets which drawing modes are available for the user to select, in the order they are displayed. This should not include the null drawing mode, which is added by default. If null, drawing controls are disabled and not displayed. Possible drawing modes are "Point", "LineString" or "Polygon".
setDrawingMode(drawingMode:string)
Return Value:  None
Sets the current drawing mode of the given Data layer. A drawing mode of null means that the user can interact with the map as normal, and clicks do not draw anything. Possible drawing modes are null, "Point", "LineString" or "Polygon".
setMap(map:Map)
Return Value:  None
Renders the features on the specified map. If map is set to null, the features will be removed from the map.
setStyle(style:Data.StylingFunction|Data.StyleOptions)
Return Value:  None
Sets the style for all features in the collection. Styles specified on a per-feature basis via overrideStyle() continue to apply.

Pass either an object with the desired style options, or a function that computes the style for each feature. The function will be called every time a feature's properties are updated.
toGeoJson(callback:function(Object))
Return Value:  None
Exports the features in the collection to a GeoJSON object.

Polygon class

google.maps.Polygon class

A polygon (like a polyline) defines a series of connected coordinates in an ordered sequence. Additionally, polygons form a closed loop and define a filled region. See the samples in the developer's guide, starting with a simple polygon, a polygon with a hole, and more. Note that you can also use the Data layer to create a polygon. The Data layer offers a simpler way of creating holes because it handles the order of the inner and outer paths for you.

This class extends MVCObject.

Constructor
Polygon(opts?:PolygonOptions) Create a polygon using the passed PolygonOptions, which specify the polygon's path, the stroke style for the polygon's edges, and the fill style for the polygon's interior regions. A polygon may contain one or more paths, where each path consists of an array of LatLngs. You may pass either an array of LatLngs or an MVCArray of LatLngs when constructing these paths. Arrays are converted to MVCArrays within the polygon upon instantiation.

OverlayView class

google.maps.OverlayView class

You can implement this class if you want to display custom types of overlay objects on the map.

Inherit from this class by setting your overlay's prototype: MyOverlay.prototype = new google.maps.OverlayView();. The OverlayView constructor is guaranteed to be an empty function.

You must implement three methods: onAdd(), draw(), and onRemove().

  • In the onAdd() method, you should create DOM objects and append them as children of the panes.
  • In the draw() method, you should position these elements.
  • In the onRemove() method, you should remove the objects from the DOM.
You must call setMap() with a valid Map object to trigger the call to the onAdd() method and setMap(null) in order to trigger the onRemove() method. The setMap() method can be called at the time of construction or at any point afterward when the overlay should be re-shown after removing. The draw() method will then be called whenever a map property changes that could change the position of the element, such as zoom, center, or map type.

This class extends MVCObject.

Constructor
OverlayView() Creates an OverlayView.
Methods
draw()
Return Value:  None
Implement this method to draw or update the overlay. This method is called after onAdd() and when the position from projection.fromLatLngToPixel() would return a new value for a given LatLng. This can happen on change of zoom, center, or map type. It is not necessarily called on drag or resize.
getMap()
Return Value:  Map|StreetViewPanorama
getPanes()
Return Value:  MapPanes
Returns the panes in which this OverlayView can be rendered. The panes are not initialized until onAdd is called by the API.
getProjection()
Return Value:  MapCanvasProjection
Returns the MapCanvasProjection object associated with this OverlayView. The projection is not initialized until onAdd is called by the API.
onAdd()
Return Value:  None
Implement this method to initialize the overlay DOM elements. This method is called once after setMap() is called with a valid map. At this point, panes and projection will have been initialized.
onRemove()
Return Value:  None
Implement this method to remove your elements from the DOM. This method is called once following a call to setMap(null).
setMap(map:Map|StreetViewPanorama)
Return Value:  None
Adds the overlay to the map or panorama.

LatLng class

google.maps.LatLng class

A LatLng is a point in geographical coordinates: latitude and longitude.

  • Latitude ranges between -90 and 90 degrees, inclusive. Values above or below this range will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
  • Longitude ranges between -180 and 180 degrees, inclusive. Values above or below this range will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.
Although the default map projection associates longitude with the x-coordinate of the map, and latitude with the y-coordinate, the latitude coordinate is always written first, followed by the longitude.
Notice that you cannot modify the coordinates of a LatLng. If you want to compute another point, you have to create a new one.

Most methods that accept LatLng objects also accept a LatLngLiteral object, so that the following are equivalent: 

 map.setCenter(new google.maps.LatLng(-34, 151));
 map.setCenter({lat: -34, lng: 151});

The constructor also accepts literal objects, and converts them to instances of LatLng: 

 myLatLng = new google.maps.LatLng({lat: -34, lng: 151});

Constructor
LatLng(lat:number, lng:number, noWrap?:boolean) Creates a LatLng object representing a geographic point. Latitude is specified in degrees within the range [-90, 90]. Longitude is specified in degrees within the range [-180, 180]. Set noWrap to true to enable values outside of this range. Note the ordering of latitude and longitude.
Methods
equals(other:LatLng)
Return Value:  boolean
Comparison function.
lat()
Return Value:  number
Returns the latitude in degrees.
lng()
Return Value:  number
Returns the longitude in degrees.
toJSON()
Return Value:  LatLngLiteral
Converts to JSON representation. This function is intended to be used via JSON.stringify.
toString()
Return Value:  string
Converts to string representation.
toUrlValue(precision?:number)
Return Value:  string
Returns a string of the form "lat,lng" for this LatLng. We round the lat/lng values to 6 decimal places by default.

LatLngLiteral object specification

google.maps.LatLngLiteral object specification

Object literals are accepted in place of LatLng objects, as a convenience, in many places. These are converted to LatLng objects when the Maps API encounters them.

Examples: 

 map.setCenter({lat: -34, lng: 151});
 new google.maps.Marker({position: {lat: -34, lng: 151}, map: map});

LatLng object literals are not supported in the Geometry library.

Properties
lat
Type:  number
Latitude in degrees. Values will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
lng
Type:  number
Longitude in degrees. Values outside the range [-180, 180] will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.

Constructor
PlacesService(attrContainer:HTMLDivElement|Map) Creates a new instance of the PlacesService that renders attributions in the specified container.
Methods
getDetails(request:PlaceDetailsRequest, callback:function(PlaceResult, PlacesServiceStatus))
Return Value:  None
Retrieves details about the place identified by the given placeId.
nearbySearch(request:PlaceSearchRequest, callback:function(Array<PlaceResult>, PlacesServiceStatus, PlaceSearchPagination))
Return Value:  None
Retrieves a list of places near a particular location, based on keyword or type. Location must always be specified, either by passing a LatLngBounds, or location and radius parameters. The PlaceResults passed to the callback are subsets of the full PlaceResult. Your app can get a more detailed PlaceResult for each place by sending a Place Details request passing the reference value for the desired place. The PlaceSearchPagination object can be used to fetch additional pages of results (null if this is the last page of results or if there is only one page of results).
radarSearch(request:RadarSearchRequest, callback:function(Array<PlaceResult>, PlacesServiceStatus))
Return Value:  None
Similar to the nearbySearch function, with the following differences: the search response will include up to 200 places, identified only by their geographic coordinates and place_id.
textSearch(request:TextSearchRequest, callback:function(Array<PlaceResult>, PlacesServiceStatus, PlaceSearchPagination))
Return Value:  None
Retrieves a list of places based on a query string (for example, "pizza in New York", or "shoe stores near Ottawa"). Location parameters are optional; when the region is specified, results are only biased toward nearby results rather than restricted to places inside the area. Use textSearch when you want to search for places using an arbitrary string, and in cases where you may not want to restrict search results to a particular location.
