id
The id for the source. Must not be used by any existing source.
map
maxzoom
The maximum zoom level for the source.
minzoom
The minimum zoom level for the source.
OptionalredFactor

Methods
abortTile
fire
hasTile
True is the tile is part of the source, false otherwise.
Parameters
- tileID: OverscaledTileID
The tile ID
Returns boolean
- tileID: OverscaledTileID
hasTransition
True if the source has transition, false otherwise.
Returns boolean
listens
Returns a true if this instance of Evented or any forwardeed instances of Evented have a listener for the specified type.
Parameters
- type: string
The event type
Returns boolean
trueif there is at least one registered listener for specified event type,falseotherwise- type: string
load
Parameters
OptionalsourceDataChanged: boolean
Returns Promise<void>
loaded
True if the source is loaded, false otherwise.
Returns boolean
loadTile
This method does the heavy lifting of loading a tile. In most cases it will defer the work to the relevant worker source.
Parameters
- tile: Tile
The tile to load
Returns Promise<void>
- tile: Tile
off
Removes a previously registered event listener.
Parameters
- type: string
The event type to remove listeners for.
- listener: Listener
The listener function to remove.
Returns this
- type: string
on
Adds a listener to a specified event type.
Parameters
- type: string
The event type to add a listen for.
- listener: Listener
The function to be called when the event is fired. The listener function is called with the data object passed to
fire, extended withtargetandtypeproperties.
Returns Subscription
- type: string
onAdd
This method is called when the source is added to the map.
Parameters
- map: MapLibreMap
The map instance
Returns void
- map: MapLibreMap
once
Adds a listener that will be called only once to a specified event type.
The listener will be called first time the event fires after the listener is registered.
Parameters
- type: string
The event type to listen for.
Optionallistener: ListenerThe function to be called when the event is fired the first time.
Returns RasterDEMTileSource | Promise<any>
thisor a promise if a listener is not provided- type: string
onRemove
This method is called when the source is removed from the map.
Returns void
readImageNow
Parameters
- img: ImageBitmap | HTMLImageElement
Returns Promise<RGBAImage | ImageData>
serialize
Returns RasterSourceSpecification | RasterDEMSourceSpecification
A plain (stringifiable) JS object representing the current state of the source. Creating a source using the returned object as the
optionsshould result in a Source that is equivalent to this one.
setEventedParent
Bubble all events fired by this instance of Evented to this parent instance of Evented.
Parameters
Optionalparent: Evented | nullOptionaldata: any
Returns this
setSourceProperty
Parameters
- callback: Function
Returns void
setTiles
Sets the source
tilesproperty and re-renders the map.Parameters
- tiles: string[]
An array of one or more tile source URLs, as in the raster tiles spec (See the Style Specification
Returns this
- tiles: string[]
setUrl
Sets the source
urlproperty and re-renders the map.Parameters
- url: string
A URL to a TileJSON resource. Supported protocols are
http:andhttps:.
Returns this
- url: string
A source containing raster DEM tiles (See the Style Specification for detailed documentation of options.) This source can be used to show hillshading and 3D terrain
