HeatmapLayer
HeatmapLayer is a style layer that renders one or more filled circles on the map.
string
required A string that uniquely identifies the source in the style to which it is added.
boolean
The id refers to en existing layer in the style. Does not create a new layer.
string
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. Inferred from parent source only if the layer is a direct child to it.
defaults to: Mapbox.StyleSource.DefaultSourceID
string
Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style.
string
Inserts a layer above aboveLayerID.
string
Inserts a layer below belowLayerID
number
Inserts a layer at a specified index
FilterExpression
Filter only the features in the source layer that satisfy a condition that you define
number
The minimum zoom level at which the layer gets parsed and appears.
number
The maximum zoom level at which the layer gets parsed and appears.
'bottom' | 'middle' | 'top'
The slot this layer is assigned to. If specified, and a slot with that name exists, it will be placed at that position in the layer order.

HeatmapLayerStyleProps
Customizable style attributes
Name: visibility
Mapbox spec: visibility
Whether this layer is displayed.
enum
visible
visible - The layer is shown.
none - The layer is not shown.
Parameters: ``
Name: heatmapRadius
Mapbox spec: heatmap-radius
Radius of influence of one heatmap point in pixels. Increasing the value makes the heatmap smoother, but less detailed. queryRenderedFeatures
on heatmap layers will return points within this radius.
number
30
pixels
1
Parameters: zoom, feature, feature-state, measure-light
Name: heatmapRadiusTransition
The transition affecting any changes to this layer’s heatmapRadius property.
{ duration, delay }
milliseconds
{duration: 300, delay: 0}
Name: heatmapWeight
Mapbox spec: heatmap-weight
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, measure-light
Name: heatmapIntensity
Mapbox spec: heatmap-intensity
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
Name: heatmapIntensityTransition
The transition affecting any changes to this layer’s heatmapIntensity property.
{ duration, delay }
milliseconds
{duration: 300, delay: 0}
Name: heatmapColor
Mapbox spec: heatmap-color
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
Name: heatmapOpacity
Mapbox spec: heatmap-opacity
The global opacity at which the heatmap layer will be drawn.
number

Parameters: zoom
Name: heatmapOpacityTransition
The transition affecting any changes to this layer’s heatmapOpacity property.
