MapOptions

MapOptions: object

The Map options object.

Type declaration

antialias?

optional antialias: boolean

If true, the gl context will be created with MSAA antialiasing, which can be useful for antialiasing custom layers. Disabled by default as a performance optimization.

attributionControl?

optional attributionControl: false | AttributionControlOptions

If set, an AttributionControl will be added to the map with the provided options. To disable the attribution control, pass false. Note: showing the logo of TrimbleMaps is not required for using TrimbleMaps.

Default Value

compact: true, customAttribution: "TrimbleMaps ...".

bearing?

optional bearing: number

The initial bearing (rotation) of the map, measured in degrees counter-clockwise from north. If bearing is not specified in the constructor options, TrimbleMaps JS will look for it in the map’s style object. If it is not specified in the style, either, it will default to 0.

Default Value

0

bearingSnap?

optional bearingSnap: number

The threshold, measured in degrees, that determines when the map’s bearing will snap to north. For example, with a bearingSnap of 7, if the user rotates the map within 7 degrees of north, the map will automatically snap to exact north.

Default Value

7

bounds?

optional bounds: LngLatBoundsLike

The initial bounds of the map. If bounds is specified, it overrides center and zoom constructor options.

boxZoom?

optional boxZoom: boolean

If true, the “box zoom” interaction is enabled (see BoxZoomHandler).

Default Value

true

cancelPendingTileRequestsWhileZooming?

optional cancelPendingTileRequestsWhileZooming: boolean

Determines whether to cancel, or retain, tiles from the current viewport which are still loading but which belong to a farther (smaller) zoom level than the current one.

• If true, when zooming in, tiles which didn’t manage to load for previous zoom levels will become canceled. This might save some computing resources for slower devices, but the map details might appear more abruptly at the end of the zoom.
• If false, when zooming in, the previous zoom level(s) tiles will progressively appear, giving a smoother map details experience. However, more tiles will be rendered in a short period of time.

Default Value

true

center?

optional center: LngLatLike

The initial geographical centerpoint of the map. If center is not specified in the constructor options, TrimbleMaps JS will look for it in the map’s style object. If it is not specified in the style, either, it will default to [0, 0] Note: TrimbleMaps JS uses longitude, latitude coordinate order (as opposed to latitude, longitude) to match GeoJSON.

Default Value

[0, 0]

clickTolerance?

optional clickTolerance: number

The max number of pixels a user can shift the mouse pointer during a click for it to be considered a valid click (as opposed to a mouse drag).

Default Value

3

collectResourceTiming?

optional collectResourceTiming: boolean

If true, Resource Timing API information will be collected for requests made by GeoJSON and Vector Tile web workers (this information is normally inaccessible from the main Javascript thread). Information will be returned in a resourceTiming property of relevant data events.

Default Value

false

container

container: HTMLElement | string

The HTML element in which TrimbleMaps JS will render the map, or the element’s string id. The specified element must have no children.

cooperativeGestures?

optional cooperativeGestures: GestureOptions

If true or set to an options object, the map is only accessible on desktop while holding Command/Ctrl and only accessible on mobile with two fingers. Interacting with the map using normal gestures will trigger an informational screen. With this option enabled, “drag to pitch” requires a three-finger gesture. Cooperative gestures are disabled when a map enters fullscreen using FullscreenControl.

Default Value

false

crossSourceCollisions?

optional crossSourceCollisions: boolean

If true, symbols from multiple sources can collide with each other during collision detection. If false, collision detection is run separately for the symbols in each source.

Default Value

true

doubleClickZoom?

optional doubleClickZoom: boolean

If true, the “double click to zoom” interaction is enabled (see DoubleClickZoomHandler).

Default Value

true

dragPan?

optional dragPan: boolean | DragPanOptions

If true, the “drag to pan” interaction is enabled. An Object value is passed as options to DragPanHandler#enable.

Default Value

true

dragRotate?

optional dragRotate: boolean

If true, the “drag to rotate” interaction is enabled (see DragRotateHandler).

Default Value

true

fadeDuration?

optional fadeDuration: number

Controls the duration of the fade-in/fade-out animation for label collisions after initial map load, in milliseconds. This setting affects all symbol layers. This setting does not affect the duration of runtime styling transitions or raster tile cross-fading.

Default Value

300

failIfMajorPerformanceCaveat?

optional failIfMajorPerformanceCaveat: boolean

If true, map creation will fail if the performance of TrimbleMaps JS would be dramatically worse than expected (i.e. a software renderer would be used).

Default Value

false

fitBoundsOptions?

optional fitBoundsOptions: FitBoundsOptions

A FitBoundsOptions options object to use only when fitting the initial bounds provided above.

hash?

optional hash: boolean | string

If true, the map’s position (zoom, center latitude, center longitude, bearing, and pitch) will be synced with the hash fragment of the page’s URL. For example, http://path/to/my/page.html#2.59/39.26/53.07/-24.1/60. An additional string may optionally be provided to indicate a parameter-styled hash, e.g. http://path/to/my/page.html#map=2.59/39.26/53.07/-24.1/60&foo=bar, where foo is a custom parameter and bar is an arbitrary hash distinct from the map hash.

Default Value

false

interactive?

optional interactive: boolean

If false, no mouse, touch, or keyboard listeners will be attached to the map, so it will not respond to interaction.

Default Value

true

keyboard?

optional keyboard: boolean

If true, keyboard shortcuts are enabled (see KeyboardHandler).

Default Value

true

language?

optional language: LanguageEnum

map’s Language if not set default would EN

localIdeographFontFamily?

optional localIdeographFontFamily: string | false

Defines a CSS font-family for locally overriding generation of glyphs in the ‘CJK Unified Ideographs’, ‘Hiragana’, ‘Katakana’ and ‘Hangul Syllables’ ranges. In these ranges, font settings from the map’s style will be ignored, except for font-weight keywords (light/regular/medium/bold). Set to false, to enable font settings from the map’s style for these glyph ranges. The purpose of this option is to avoid bandwidth-intensive glyph server requests. (See Use locally generated ideographs.)

Default Value

'sans-serif'

locale?

optional locale: any

A patch to apply to the default localization table for UI strings, e.g. control tooltips. The locale object maps namespaced UI string IDs to translated strings in the target language; see src/ui/default_locale.js for an example with all supported string IDs. The object may specify all UI strings (thereby adding support for a new translation) or only a subset of strings (thereby patching the default translation table).

Default Value

null

logoPosition?

optional logoPosition: ControlPosition

A string representing the position of the TrimbleMaps wordmark on the map. Valid options are top-left,top-right, bottom-left, or bottom-right.

The maximum zoom level of the map (0-24).

Default Value

22

minPitch?

preserveDrawingBuffer?

optional preserveDrawingBuffer: boolean

If true, the map’s canvas can be exported to a PNG using map.getCanvas().toDataURL(). This is false by default as a performance optimization.

Default Value

false

refreshExpiredTiles?

optional refreshExpiredTiles: boolean

If false, the map won’t attempt to re-request tiles once they expire per their HTTP cacheControl/expires headers.

Default Value

true

region?

optional region: RegionEnum
