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. Default value: 512. Minimum value: 1.
Defines defines the opacity coefficient applied to the faded particles in each frame. In practice, this property controls the length of the particle tail. Default value: 0.98. Value range: 0, 1
Defines the transition of rasterParticleFadeOpacityFactor. Default value: 0.98. Value range: 0, 1
Defines the maximum speed for particles. Velocities with magnitudes equal to or exceeding this value are clamped to the max value. Default value: 1. Minimum value: 1.
Defines a coefficient for a time period at which particles will restart at a random position, to avoid degeneration (empty areas without particles). Default value: 0.8. Value range: 0, 1
Defines a coefficient for the speed of particles’ motion. Default value: 0.2. Value range: 0, 1
Defines the transition of rasterParticleSpeedFactor. Default value: 0.2. Value range: 0, 1
Whether this layer is displayed. Default value: "visible".
The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden. Value range: 0, 24
The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden. Value range: 0, 24
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.
