Heatmap Layer
A heatmap.

Parameters
the source that drives this layer.
the ID of the layer, by default, a random id will be generated with UUID.
Defines the color of each pixel based on its density value in a heatmap. Should be an expression that uses ["heatmap-density"]
as input.
Similar to heatmap-weight
but controls the intensity of the heatmap globally. Primarily used for adjusting the heatmap based on zoom level.
The global opacity at which the heatmap layer will be drawn.
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.
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.
Whether this layer is displayed.
The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.
The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.
Layer to use from a vector tile source. Required for vector tile sources; prohibited for all other source types, including GeoJSON sources.
An expression specifying conditions on source features. Only features that match the filter are displayed. Zoom expressions in filters are only evaluated at integer zoom levels. The ["feature-state", ...]
expression is not supported in filter expressions. The ["pitch"]
and ["distance-from-center"]
expressions are supported only for filter expressions on the symbol layer.
