A
DataSource
which processes Keyhole Markup Language 2.2 (KML).
KML support in Cesium is incomplete, but a large amount of the standard,
as well as Google's gx
extension namespace, is supported. See Github issue
#873 for a
detailed list of what is and isn't support. Cesium will also write information to the
console when it encounters most unsupported features.
Non visual feature data, such as atom:author
and ExtendedData
is exposed via an instance of KmlFeatureData
, which is added to each Entity
under the kml
property.
Name | Type | Description |
---|---|---|
options.camera |
Camera | The camera that is used for viewRefreshModes and sending camera properties to network links. |
options.canvas |
Canvas | The canvas that is used for sending viewer properties to network links. |
options.proxy |
DefaultProxy | optional A proxy to be used for loading external data. |
Example:
var viewer = new Cesium.Viewer('cesiumContainer');
viewer.dataSources.add(Cesium.KmlDataSource.load('../../SampleData/facilities.kmz'),
{
camera: viewer.scene.camera,
canvas: viewer.scene.canvas
});

Members
-
changedEvent : Event
-
Gets an event that will be raised when the underlying data changes.
-
Gets the clock settings defined by the loaded KML. This represents the total availability interval for all time-dynamic data. If the KML does not contain time-dynamic data, this value is undefined.
-
Gets the collection of
Entity
instances. -
errorEvent : Event
-
Gets an event that will be raised if an error is encountered during processing.
-
Gets a value indicating if the data source is currently loading data.
-
loadingEvent : Event
-
Gets an event that will be raised when the data source either starts or stops loading.
-
Gets a human-readable name for this instance. This will be automatically be set to the KML document name on load.
-
refreshEvent : Event
-
Gets an event that will be raised when the data source refreshes a network link.
-
Gets whether or not this data source should be displayed.
Methods
-
staticCesium.KmlDataSource.load(data, options) → Promise.<KmlDataSource>
