Map

The Map object represents the map on your page. It exposes methods and properties that enable you to programmatically change the map, and fires events as users interact with it.

You create a Map by specifying a container and other options, see MapOptions for the full list. Then TrimbleMaps JS initializes the map on the page and returns your Map object.

Example

let map = new TrimbleMaps.Map({
  container: 'map',
  center: [-122.420679, 37.772537],
  zoom: 13,
  style: style_object,
  hash: true,
  transformRequest: (url, resourceType)=> {
    if(resourceType === 'Source' && url.startsWith('http://myHost')) {
      return {
       url: url.replace('http', 'https'),
       headers: { 'my-custom-header': true},
       credentials: 'include'  // Include cookies for cross-origin requests
     }
    }
  }
});

Returns a Point representing pixel coordinates, relative to the map’s container, that correspond to the specified geographical location.

Parameters

Returns

let point = map.project(coordinate);

queryRenderedFeatures()

queryRenderedFeatures(geometryOrOptions?: PointLike | QueryRenderedFeaturesOptions | [PointLike, PointLike], options?: QueryRenderedFeaturesOptions): MapGeoJSONFeature[]

Returns an array of MapGeoJSONFeature objects representing visible features that satisfy the query parameters.

Parameters

Returns

MapGeoJSONFeature[]

An array of MapGeoJSONFeature objects.

The properties value of each returned feature object contains the properties of its source feature. For GeoJSON sources, only string and numeric property values are supported (i.e. null, Array, and Object values are not supported).

Each feature includes top-level layer, source, and sourceLayer properties. The layer property is an object representing the style layer to which the feature belongs. Layout and paint properties in this object contain values which are fully evaluated for the given zoom level and feature.

Only features that are currently rendered are included. Some features will not be included, like:

• Features from layers whose visibility property is "none".
• Features from layers whose zoom range excludes the current zoom level.
• Symbol features that have been hidden due to text or icon collision.

Features from all other layers are included, including features that may have no visible contribution to the rendered result; for example, because the layer’s opacity or color alpha component is set to 0.

The topmost rendered feature appears first in the returned array, and subsequent features are sorted by descending z-order. Features that are rendered multiple times (due to wrapping across the antemeridian at low zoom levels) are returned only once (though subject to the following caveat).

Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple times in query results. For example, suppose there is a highway running through the bounding rectangle of a query. The results of the query will be those parts of the highway that lie within the map tiles covering the bounding rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple tiles due to tile buffering.

Examples

Find all features at a point

let features = map.queryRenderedFeatures(
  [20, 35],
  { layers: ['my-layer-name'] }
);

Find all features within a static bounding box

let features = map.queryRenderedFeatures(
  [[10, 20], [30, 50]],
  { layers: ['my-layer-name'] }
);

Find all features within a bounding box around a point

let width = 10;
let height = 20;
let features = map.queryRenderedFeatures([
  [point.x - width / 2, point.y - height / 2],
  [point.x + width / 2, point.y + height / 2]
], { layers: ['my-layer-name'] });

Query all rendered features from a single layer

let features = map.queryRenderedFeatures({ layers: ['my-layer-name'] });

Get features under the mouse pointer

querySourceFeatures()

querySourceFeatures(sourceId: string, parameters?: QuerySourceFeatureOptions): MapGeoJSONFeature[]

Returns an array of MapGeoJSONFeature objects representing features within the specified vector tile or GeoJSON source that satisfy the query parameters.

Parameters

Returns

MapGeoJSONFeature[]

An array of MapGeoJSONFeature objects.

In contrast to Map#queryRenderedFeatures, this function returns all features matching the query parameters, whether or not they are rendered by the current style (i.e. visible). The domain of the query includes all currently-loaded vector tiles and GeoJSON source tiles: this function does not check tiles outside the currently visible viewport.

Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple times in query results. For example, suppose there is a highway running through the bounding rectangle of a query. The results of the query will be those parts of the highway that lie within the map tiles covering the bounding rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple tiles due to tile buffering.

Example

Find all features in one source layer in a vector source

let features = map.querySourceFeatures('your-source-id', {
  sourceLayer: 'your-source-layer'
});

queryTerrainElevation()

queryTerrainElevation(lngLatLike: LngLatLike): number

setFeatureState()

setFeatureState(feature: FeatureIdentifier, state: any): this

Sets the state of a feature. A feature’s state is a set of user-defined key-value pairs that are assigned to a feature at runtime. When using this method, the state object is merged with any existing key-value pairs in the feature’s state. Features are identified by their feature.id attribute, which can be any number or string.

This method can only be used with sources that have a feature.id attribute. The feature.id attribute can be defined in three ways:

• For vector or GeoJSON sources, including an id attribute in the original data file.
• For vector or GeoJSON sources, using the promoteId option at the time the source is defined.
• For GeoJSON sources, using the generateId option to auto-assign an id based on the feature’s index in the source data. If you change feature data using map.getSource('some id').setData(..), you may need to re-apply state taking into account updated id values.

Note: You can use the feature-state expression to access the values in a feature’s state object for the purposes of styling.

Parameters

Returns

this

Example

// When the mouse moves over the `my-layer` layer, update
// the feature state for the feature under the mouse
map.on('mousemove', 'my-layer', (e) => {
  if (e.features.length > 0) {
    map.setFeatureState({
      source: 'my-source',
      sourceLayer: 'my-source-layer',
      id: e.features[0].id,
    }, {
      hover: true
    });
  }
});

Parameters

Returns

Map

Example

map.setMaxZoom(18.75);

setMinPitch()

setMinPitch(minPitch?: number): Map

If a style is already set when this is used and options.diff is set to true, the map renderer will attempt to compare the given style against the map’s current state and perform only the changes necessary to make the map style match the desired state. Changes in sprites (images used for icons and patterns) and glyphs (fonts for label text) cannot be diffed. If the sprites or fonts used in the current style and the given style are different in any way, the map renderer will force a full update, removing the current style and building the given one from scratch.

Parameters

Returns

this

Example
