Layers | Mapbox Style Spec | Mapbox Docs (original) (raw)

A style's layers property lists all the layers available in that style. The type of layer is specified by the "type" property, and must be one of background, circle, fill, fill-extrusion, heatmap, hillshade, line, model, raster, raster-particle, symbol, sky.

Except for layers of the background or sky types, each layer must refer to a source. Layers take the data that they get from a source, optionally filter features, and then define how those features are styled.

Here is an example layers object which could be included in a style:

Layer properties​

id​

Unique layer name.

type​

Required

enum

.

One of

"fill", "line", "symbol", "circle", "heatmap", "fill-extrusion", "building", "raster", "raster-particle", "hillshade", "model", "background", "sky", "slot", "clip".

Rendering type of this layer.

"fill":

A filled polygon with an optional stroked border.

"line":

A stroked line.

"symbol":

An icon or a text label.

"circle":

A filled circle.

"heatmap":

"raster":

Raster map textures such as satellite imagery.

"raster-particle":

The background color or pattern of the map.

"sky":

A spherical dome around the map that is always rendered behind all other layers.

"slot":

Marks the position of a slot.

"clip":

Layer that removes 3D content from map.

filter​

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.

layout​

Layout properties for the layer.

maxzoom​

Optional

number between 0 and 24 inclusive.

The maximum zoom level for the layer. At zoom levels equal to or greater than the maxzoom, the layer will be hidden.

Arbitrary properties useful to track with the layer, but do not influence rendering. Properties should be prefixed to avoid collisions, like 'mapbox:'.

minzoom​

Optional

number between 0 and 24 inclusive.

The minimum zoom level for the layer. At zoom levels less than the minzoom, the layer will be hidden.

paint​

Default paint properties for this layer.

slot​

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.

source​

Name of a source description to be used for this layer. Required for all layer types except background and slot.

source-layer​

Layer to use from a vector tile source. Required for vector and raster-array sources; prohibited for all other source types, including GeoJSON sources.

Layer sub-properties​

Layers have two sub-properties that determine how data from that layer is rendered: layout and paint properties.

Layout properties​

Layout properties appear in the layer's "layout" object. They are applied early in the rendering process and define how data for that layer is passed to the GPU. Changes to a layout property require an asynchronous "layout" step.

Paint properties​

Paint properties are applied later in the rendering process. Paint properties appear in the layer's "paint" object. Changes to a paint property are cheap and happen synchronously.

background​

The background style layer covers the entire map. Use a background style layer to configure a color or pattern to show below all other map content. If the background layer is transparent or omitted from the style, any part of the map view that does not show another style layer is transparent.

This cluster map uses a circle layer with a GeoJSON data source and sets the source's cluster property to true to visualize points as clusters.

Requires fill-extrusion-edge-radius.

Supports

smooth-rampinterpolate

expressions.

opacityTransitionable.

Shades area near ground and concave angles between walls where the radius defines only vertical impact.

Defaults to 0.

This parameter defines the range for the fade-out effect before an automatic content cutoff on pitched map views. Fade out is implemented by scaling down and removing buildings in the fade range in a staggered fashion. Opacity is not changed. The fade range is expressed in relation to the height of the map view. A value of 1.0 indicates that the content is faded to the same extent as the map's height in pixels, while a value close to zero represents a sharp cutoff. When the value is set to 0.0, the cutoff is completely disabled. Note: The property has no effect on the map if terrain is enabled.

2. batched-model (Used for landmark buildings in standard style)

To place third party models on the map the first approach should be used. It's possible to adjust rotation, scale, color, color mix and level of details for the models using the properties of the model layer.

A value of 1.0 indicates that the content is faded to the same extent as the map's height in pixels, while a value close to zero represents a sharp cutoff. When the value is set to 0.0, the cutoff is completely disabled. Note: The property has no effect on the map if terrain is enabled.

Optional

array of numbers

[ between 0 and 360 inclusive, between 0 and 180 inclusive

]

.

Units in degrees.

Requires sky-type to be "atmosphere".

Position of the sun center [a azimuthal angle, p polar angle]. The azimuthal angle indicates the position of the sun relative to 0° north, where degrees proceed clockwise. The polar angle indicates the height of the sun, where 0° is directly above, at zenith, and 90° at the horizon. When this property is ommitted, the sun center is directly inherited from the light position.

sky-atmosphere-sun-intensity​

Paint

property.

Optional

number between 0 and 100 inclusive.

Defaults to 10.

Requires sky-type to be "atmosphere".

Intensity of the sun as a light source in the atmosphere (on a scale from 0 to a 100). Setting higher values will brighten up the sky.

sky-gradient​

Paint

property.

Optional

color

.

Defaults to ["interpolate",["linear"],["sky-radial-progress"],0.8,"#87ceeb",1,"white"].

Requires sky-type to be "gradient".

Supports

smooth-rampinterpolate

expressions.

Defines a radial color gradient with which to color the sky. The color values can be interpolated with an expression using sky-radial-progress. The range [0, 1] for the interpolant covers a radial distance (in degrees) of [0, sky-gradient-radius] centered at the position specified by sky-gradient-center.

sky-gradient-center​

Paint

property.

Optional

array of numbers

[ between 0 and 360 inclusive, between 0 and 180 inclusive

]

.

Units in degrees.

Defaults to [0,0].

Requires sky-type to be "gradient".

Position of the gradient center [a azimuthal angle, p polar angle]. The azimuthal angle indicates the position of the gradient center relative to 0° north, where degrees proceed clockwise. The polar angle indicates the height of the gradient center, where 0° is directly above, at zenith, and 90° at the horizon.

sky-gradient-radius​

Paint

property.

Optional

number between 0 and 180 inclusive.

Defaults to 90.

Requires sky-type to be "gradient".

The angular distance (measured in degrees) from sky-gradient-center up to which the gradient extends. A value of 180 causes the gradient to wrap around to the opposite direction from sky-gradient-center.

sky-opacity​

The opacity of the entire sky layer.

sky-type​

Paint

property.

Optional

enum

.

One of

"gradient", "atmosphere".

Defaults to "atmosphere".

The type of the sky

"gradient":

Renders the sky with a gradient that can be configured with sky-gradient-radius and sky-gradient.

"atmosphere":

Renders the sky with a simulated atmospheric scattering algorithm, the sun direction can be attached to the light position or explicitly set through sky-atmosphere-sun.

visibility​

Layout

property.

Optional

enum

.

One of

"visible", "none".

Defaults to "visible".

Whether this layer is displayed.

"visible":

The layer is shown.

"none":

The layer is not shown.
