KML

KmlLayerclass

google.maps.KmlLayerclass

AKmlLayer adds geographic markup to the map from a KML, KMZ or GeoRSS file that is hosted on a publicly accessible web server. AKmlFeatureData object is provided for each feature when clicked.

This class extendsMVCObject.

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

Constructor
`KmlLayer`	`KmlLayer([opts])` Parameters: `opts`: `KmlLayerOptionsoptional` Options for this layer. Creates a`KmlLayer` which renders the contents of the specified KML/KMZ file (https://developers.google.com/kml/documentation/kmlreference) or GeoRSS file (http://www.georss.org).

Methods
`getDefaultViewport`	`getDefaultViewport()` Parameters: None Return Value: `LatLngBounds` Get the default viewport for the layer being displayed.
`getMap`	`getMap()` Parameters: None Return Value: `Map` Get the map on which the KML Layer is being rendered.
`getMetadata`	`getMetadata()` Parameters: None Return Value: `KmlLayerMetadata` Get the metadata associated with this layer, as specified in the layer markup.
`getStatus`	`getStatus()` Parameters: None Return Value: `KmlLayerStatus` Get the status of the layer, set once the requested document has loaded.
`getUrl`	`getUrl()` Parameters: None Return Value: `string` URL Gets the URL of the KML file being displayed.
`getZIndex`	`getZIndex()` Parameters: None Return Value: `number` The z-index. Gets the z-index of the KML Layer.
`setMap`	`setMap(map)` Parameters: `map`: `Map` Return Value: None Renders the KML Layer on the specified map. If map is set to`null`, the layer is removed.
`setOptions`	`setOptions(options)` Parameters: `options`: `KmlLayerOptions` Return Value: None
`setUrl`	`setUrl(url)` Parameters: `url`: `string` Return Value: None Sets the URL of the KML file to display.
`setZIndex`	`setZIndex(zIndex)` Parameters: `zIndex`: `number` The z-index to set. Return Value: None Sets the z-index of the KML Layer.

Events
`click`	`function(kmlClickEvent)` Arguments: `kmlClickEvent`: `KmlMouseEvent` This event is fired when a feature in the layer is clicked.
`defaultviewport_changed`	`function()` Arguments: None This event is fired when the KML layers default viewport has changed.
`status_changed`	`function()` Arguments: None This event is fired when the KML layer has finished loading. At this point it is safe to read the status property to determine if the layer loaded successfully.

`preserveViewportoptional`	Type: `booleanoptional` Default:`false` If this option is set to`true` or if the map's center and zoom were never set, the input map is centered and zoomed to the bounding box of the contents of the layer.
`screenOverlaysoptional`	Type: `booleanoptional` Default:`true` Whether to render the screen overlays.
`suppressInfoWindowsoptional`	Type: `booleanoptional` Suppress the rendering of info windows when layer features are clicked.
`urloptional`	Type: `stringoptional` The URL of the KML document to display.
`zIndexoptional`	Type: `numberoptional` The z-index of the layer.

KmlLayerMetadatainterface

google.maps.KmlLayerMetadatainterface

Metadata for a single KML layer, in JSON format.

Properties
`description`	Type: `string` The layer's`<description>`, extracted from the layer markup.
`hasScreenOverlays`	Type: `boolean` Whether the layer has any screen overlays.
`name`	Type: `string` The layer's`<name>`, extracted from the layer markup.

`authoroptional`	Type: `KmlAuthoroptional` The layer's`<atom:author>`, extracted from the layer markup.

KmlLayerStatusconstants

google.maps.KmlLayerStatusconstants

The status returned byKmlLayer on the completion of loading a document. Specify these by value, or by using the constant's name. For example,'OK' orgoogle.maps.KmlLayerStatus.OK.

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

Constants
`DOCUMENT_NOT_FOUND`	The document could not be found. Most likely it is an invalid URL, or the document is not publicly available.
`DOCUMENT_TOO_LARGE`	The document exceeds the file size limits of KmlLayer.
`FETCH_ERROR`	The document could not be fetched.
`INVALID_DOCUMENT`	The document is not a valid KML, KMZ or GeoRSS document.
`INVALID_REQUEST`	The`KmlLayer` is invalid.
`LIMITS_EXCEEDED`	The document exceeds the feature limits of KmlLayer.
`OK`	The layer loaded successfully.
`TIMED_OUT`	The document could not be loaded within a reasonable amount of time.
`UNKNOWN`	The document failed to load for an unknown reason.

KmlMouseEventinterface

google.maps.KmlMouseEventinterface

The properties of a click event on a KML/KMZ or GeoRSS document.

Properties
`featureData`	Type: `KmlFeatureData` A`KmlFeatureData` object, containing information about the clicked feature.
`latLng`	Type: `LatLng` The position at which to anchor an infowindow on the clicked feature.
`pixelOffset`	Type: `Size` The offset to apply to an infowindow anchored on the clicked feature.

Data for a single KML feature in JSON format, returned when a KML feature is clicked. The data contained in this object mirrors that associated with the feature in the KML or GeoRSS markup in which it is declared.
