| Prop | Type | Default | Required | Description |
|---|---|---|---|---|
| id | string |
none |
false |
A string that uniquely identifies the source in the style to which it is added. |
| sourceID | string |
MapboxGL.StyleSource.DefaultSourceID |
false |
The source from which to obtain the data to style. If the source has not yet been added to the current style, the behavior is undefined. |
| sourceLayerID | string |
none |
false |
Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style. |
| aboveLayerID | string |
none |
false |
Inserts a layer above aboveLayerID. |
| belowLayerID | string |
none |
false |
Inserts a layer below belowLayerID |
| layerIndex | number |
none |
false |
Inserts a layer at a specified index |
| filter | array |
none |
false |
Filter only the features in the source layer that satisfy a condition that you define |
| minZoomLevel | number |
none |
false |
The minimum zoom level at which the layer gets parsed and appears. |
| maxZoomLevel | number |
none |
false |
The maximum zoom level at which the layer gets parsed and appears. |
| style | union |
none |
false |
Customizable style attributes |
visibility
Whether this layer is displayed.
enum
visible
visible - The layer is shown.
none - The layer is not shown.
heatmapRadius
Radius of influence of one heatmap point in pixels. Increasing the value makes the heatmap smoother, but less detailed.
number
30
pixels
1
Parameters: zoom, feature, feature-state
heatmapRadiusTransition
The transition affecting any changes to this layer’s heatmapRadius propery.
{ duration, delay }
milliseconds
{duration: 300, delay: 0}
heatmapWeight
A measure of how much an individual point contributes to the heatmap. A value of 10 would be equivalent to having 10 points of weight 1 in the same spot. Especially useful when combined with clustering.
number
1
0
Parameters: zoom, feature, feature-state
heatmapIntensity
Similar to heatmapWeight but controls the intensity of the heatmap globally. Primarily used for adjusting the heatmap based on zoom level.
number
1
0
Parameters: zoom
heatmapIntensityTransition
The transition affecting any changes to this layer’s heatmapIntensity propery.
{ duration, delay }
milliseconds
{duration: 300, delay: 0}
heatmapColor
Defines the color of each pixel based on its density value in a heatmap. Should be an expression that uses ["heatmapDensity"] as input.
color
interpolate,linear,heatmap-density,0,rgba(0, 0, 255, 0),0.1,royalblue,0.3,cyan,0.5,lime,0.7,yellow,1,red
Parameters: heatmap-density
heatmapOpacity
The global opacity at which the heatmap layer will be drawn.
number
1
0
1
Parameters: zoom
heatmapOpacityTransition
The transition affecting any changes to this layer’s heatmapOpacity propery.
{ duration, delay }
