Interface TileAdapterOptions

Parameters that can be used to create any map layer adapter.



adapter?: string
attribution?: string

String to be shown in the attribution control. It describes the layer data and is often a legal obligation towards copyright holders and tile providers.

baselayer?: boolean

Indicate on a cartographic base layer.

crossOrigin?: "anonymous"

Parameter added when forming a request for layer data. This is needed if you want to access tile pixel data. Refer to CORS Settings for valid String values.

fit?: boolean

Fit map to layer extent

Default Value

headers?: Record<string, any>
id?: string

Unique Layer ID. If not specified, will be added automatically.


If the layer adapter is asynchronous, its id will be assigned only after the promise is resolved. While adapter is loading, methods for obtaining layers will ignore the added layer.

layers?: string
maxScale?: number

TODO: replace by maxZoom


use maxZoom instead

maxZoom?: number

Maximum zoom level of the map.

minScale?: number

TODO: replace by minZoom


use minZoom instead

minZoom?: number

Minimum zoom level of the map.

name?: string

Non-unique name of the layer. Can be used for user interfaces.

nativeOptions?: Record<string, any>

Map and layer adapter base options Use with care. There may be a conflict in the addLayer method by the adapter of the NextGIS Frontend library

onAdded?: ((layer) => void)

Type declaration

opacity?: number

Layer transparency. From 0-transparent to 1-visible

Default Value

order?: number

Indicates the map layers display sequence. A layer with a larger order value overlaps smaller ones. Zero value used to indicate baselayer. If the value is not specified explicitly, it will be assigned automatically with an increase of one for each new layer.

props?: Record<string, any>

Any properties to save in layer. May be useful to get additional info from layer event.

ratio?: number
setViewDelay?: number

Experimental option to set the map loading delay when changing position

srs?: number

Experimental only for Ol yet

subdomains?: string | string[]
tileSize?: number

Type for geometries painting, for each layer may be only one of: point, polygon or line.

url: string
visibility?: boolean

Show layer on the map immediately after adding. Such layers are always under others. Only one base layer can be displayed on the map at a time.


TODO: replace by show

Default Value

waitFullLoad?: boolean

Wait until the layer data is fully loaded before allowing added to the map.


If true, addLayer promise resolve only after data loading. This is useful for GeoJson vector layer adapters when you need to process downloaded data before displaying.
