Particle animation driven by textures such as wind maps.

Parameters
the source that drives this layer.
the ID of the layer, by default, a random id will be generated with UUID.
Displayed band of raster array source layer
Defines a color map by which to colorize a raster particle layer, parameterized by the ["raster-particle-speed"] expression and evaluated at 256 uniformly spaced steps over the range specified by raster-particle-max-speed.
Defines the amount of particles per tile.
Defines defines the opacity coefficient applied to the faded particles in each frame. In practice, this property controls the length of the particle tail.
Defines the maximum speed for particles. Velocities with magnitudes equal to or exceeding this value are clamped to the max value.
Defines a coefficient for a time period at which particles will restart at a random position, to avoid degeneration (empty areas without particles).
Defines a coefficient for the speed of particles’ motion.
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.
