RasterDEMTileSource

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

Example

map.addSource('raster-dem-source', {
     type: 'raster-dem',
     url: 'https://demotiles.maplibre.org/terrain-tiles/tiles.json',
     tileSize: 256
});

Methods

abortTile()

abortTile(tile: Tile): Promise<void>

Allows to abort a tile loading.

Parameters

Parameter	Type	Description
`tile`	`Tile`	The tile to abort

Returns

Promise<void>

hasTile()

hasTile(tileID: OverscaledTileID): boolean

True is the tile is part of the source, false otherwise.

Parameters

Parameter	Type	Description
`tileID`	`OverscaledTileID`	The tile ID

Returns

boolean

hasTransition()

hasTransition(): boolean

True if the source has transition, false otherwise.

Returns

boolean

listens()

listens(type: string): boolean

Returns a true if this instance of Evented or any forwardeed instances of Evented have a listener for the specified type.

Parameters

Parameter	Type	Description
`type`	`string`	The event type

Returns

boolean

true if there is at least one registered listener for specified event type, false otherwise

loaded()

loaded(): boolean

True if the source is loaded, false otherwise.

Returns

boolean

off()

off(type: string, listener: Listener): RasterDEMTileSource

Removes a previously registered event listener.

Parameters

Parameter	Type	Description
`type`	`string`	The event type to remove listeners for.
`listener`	`Listener`	The listener function to remove.

Returns

RasterDEMTileSource

Inherited from

RasterTileSource.off

Defined in

src/util/evented.ts:86

on()

on(type: string, listener: Listener): this

Adds a listener to a specified event type.

Parameters

Parameter	Type	Description
`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 with `target` and `type` properties.

Returns

this

onAdd()

onAdd(map: Map): void

This method is called when the source is added to the map.

Parameters

Parameter	Type	Description
`map`	`Map`	The map instance

Returns

void

once()

once(type: string, listener?: Listener): Promise<any> | RasterDEMTileSource

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

Parameter	Type	Description
`type`	`string`	The event type to listen for.
`listener`?	`Listener`	The function to be called when the event is fired the first time.

Returns

Promise<any> | RasterDEMTileSource

this or a promise if a listener is not provided

Inherited from

RasterTileSource.once

Defined in

src/util/evented.ts:102

serialize()

serialize(): RasterSourceSpecification | RasterDEMSourceSpecification

Returns

RasterSourceSpecification | RasterDEMSourceSpecification

A plain (stringifiable) JS object representing the current state of the source. Creating a source using the returned object as the options should result in a Source that is equivalent to this one.
