Data

Data class

google.maps.Data class

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

EveryMaphas aDataobject 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(...);

TheDataobject is a collection ofFeatures.

This class extends MVCObject.

Access by callingconst {Data} = await google.maps.importLibrary( "maps" ).SeeLibraries in the Maps JavaScript API.

Constructor
`Data`	`Data([options])` Parameters: `options`:`Data.DataOptionsoptional` Creates an empty collection, with the given`DataOptions`.

Methods
`add`	`add([feature])` Parameters: `feature`:`Data.Feature\|Data.FeatureOptionsoptional` 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`	`addGeoJson(geoJson[, options])` Parameters: `geoJson`:`Object` `options`:`Data.GeoJsonOptionsoptional` 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`	`contains(feature)` Parameters: `feature`:`Data.Feature` Return Value:`boolean` Checks whether the given feature is in the collection.
`forEach`	`forEach(callback)` Parameters: `callback`:`function(Data.Feature): void` 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`	`getControlPosition()` Parameters:None Return Value:`ControlPosition` Returns the position of the drawing controls on the map.
`getControls`	`getControls()` Parameters:None 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`	`getDrawingMode()` Parameters:None Return Value:`string\|null` 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`	`getFeatureById(id)` Parameters: `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`	`getMap()` Parameters:None Return Value:`Map` Returns the map on which the features are displayed.
`getStyle`	`getStyle()` Parameters:None Return Value:`Data.StylingFunction\|Data.StyleOptions` Gets the style for all features in the collection.
`loadGeoJson`	`loadGeoJson(url[, options, callback])` Parameters: `url`:`string` `options`:`Data.GeoJsonOptionsoptional` `callback`:`function(Array<Data.Feature>): voidoptional` Return Value:None Loads GeoJSON from a URL, and adds the features to the collection. NOTE: The GeoJSON is fetched using XHR, and may not work cross-domain. If you have issues, we recommend you fetch the GeoJSON using your choice of AJAX library, and then call`addGeoJson()`.
`overrideStyle`	`overrideStyle(feature, style)` Parameters: `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`	`remove(feature)` Parameters: `feature`:`Data.Feature` Return Value:None Removes a feature from the collection.
`revertStyle`	`revertStyle([feature])` Parameters: `feature`:`Data.Featureoptional` 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`	`setControlPosition(controlPosition)` Parameters: `controlPosition`:`ControlPosition` Return Value:None Sets the position of the drawing controls on the map.
`setControls`	`setControls(controls)` Parameters: `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`	`setDrawingMode(drawingMode)` Parameters: `drawingMode`:`stringoptional` 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`	`setMap(map)` Parameters: `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`	`setStyle(style)` Parameters: `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`	`toGeoJson(callback)` Parameters: `callback`:`function(Object): void` Return Value:None Exports the features in the collection to a GeoJSON object.
Inherited: `addListener`, `bindTo`, `get`, `notify`, `set`, `setValues`, `unbind`, `unbindAll`
