Mapbox Style Specification¶

A Mapbox style is a document that defines the visual appearance of a map: what data to draw, the order to draw it in, and how to style the data when drawing it. A style document is a JSON object with specific root level and nested properties. This specification defines and describes these properties.

The intended audience of this quick reference includes:

Advanced designers and cartographers who want to write styles by hand
GeoTools developers using the mbstyle module
Authors of software that generates or processes Mapbox styles.
Feature support is provided for the Mapbox GL JS, Open Layers and the GeoTools mbstyle module.
Where appropriate examples have been changed to reference GeoWebCache.

Note

The Mapbox Style Specification is generated from the BSD Mapbox GL JS github repository, reproduced here with details on this GeoTools implementation.

Root Properties¶

Root level properties of a Mapbox style specify the map’s layers, tile sources and other resources, and default values for the initial camera position when not specified elsewhere.

Sources¶

Sources supply data to be shown on the map. The type of source is specified by the "type" property, and must be one of vector, raster, geojson, image, video, canvas. Adding a source won’t immediately make data appear on the map because sources don’t contain styling details like color or width. Layers refer to a source and give it a visual representation. This makes it possible to style the same source in different ways, like differentiating between types of roads in a highways layer.

Tiled sources (vector and raster) must specify their details in terms of the TileJSON specification. This can be done in several ways:

By supplying TileJSON properties such as "tiles", "minzoom", and "maxzoom" directly in the source:

"mapbox-streets": {
  "type": "vector",
  "tiles": [
    "http://a.example.com/tiles/{z}/{x}/{y}.pbf",
    "http://b.example.com/tiles/{z}/{x}/{y}.pbf"
  ],
  "maxzoom": 14
}

By providing a "url" to a TileJSON resource:

"mapbox-streets": {
  "type": "vector",
  "url": "http://api.example.com/tilejson.json"
}

By providing a url to a WMS server that supports EPSG:3857 (or EPSG:900913) as a source of tiled data. The server url should contain a "{bbox-epsg-3857}" replacement token to supply the bbox parameter.

"wms-imagery": {
  "type": "raster",
  "tiles": [
  'http://a.example.com/wms?bbox={bbox-epsg-3857}&format=image/png&service=WMS&version=1.1.1&request=GetMap&srs=EPSG:3857&width=256&height=256&layers=example'
  ],
  "tileSize": 256
}

vector¶

A vector tile source. Tiles must be in Mapbox Vector Tile format. All geometric coordinates in vector tiles must be between -1 * extent and (extent * 2) - 1 inclusive. All layers that use a vector source must specify a "source-layer" value. For vector tiles hosted by Mapbox, the "url" value should be of the form mapbox://mapid.

"mapbox-streets": {
  "type": "vector",
  "tiles": [
    "http://localhost:8080/geoserver/gwc/service/wmts?REQUEST=GetTile&SERVICE=WMTS

basic functionality	>= 0.32.0	Not yet supported	Not yet yupported

Sprite¶

A style’s sprite property supplies a URL template for loading small images to use in rendering background-pattern, fill-pattern, line-pattern, and icon-image style properties.

"sprite" : "/geoserver/styles/mark"

A valid sprite source must supply two types of files:

An index file, which is a JSON document containing a description of each image contained in the sprite. The content of this file must be a JSON object whose keys form identifiers to be used as the values of the above style properties, and whose values are objects describing the dimensions (width and height properties) and pixel ratio (pixelRatio) of the image and its location within the sprite (x and y). For example, a sprite containing a single image might have the following index file contents:
```
{
  "poi": {
    "width": 32,
    "height": 32,
    "x": 0,
    "y": 0,
    "pixelRatio": 1
  }
}
```
Then the style could refer to this sprite image by creating a symbol layer with the layout property "icon-image": "poi", or with the tokenized value "icon-image": "{icon}" and vector tile features with a icon property with the value poi.
Image files, which are PNG images containing the sprite data.

Mapbox SDKs will use the value of the sprite property in the style to generate the URLs for loading both files. First, for both file types, it will append @2x to the URL on high-DPI devices. Second, it will append a file extension: .json for the index file, and .png for the image file. For example, if you specified "sprite": "https://example.com/sprite", renderers would load https://example.com/sprite.json and https://example.com/sprite.png, or https://example.com/sprite@2x.json and https://example.com/sprite@2x.png.

If you are using Mapbox Studio, you will use prebuilt sprites provided by Mapbox, or you can upload custom SVG images to build your own sprite. In either case, the sprite will be built automatically and supplied by Mapbox APIs. If you want to build a sprite by hand and self-host the files, you can use spritezero-cli, a command line utility that builds Mapbox GL compatible sprite PNGs and index files from a directory of SVGs.

Glyphs¶

A style’s glyphs property provides a URL template for loading signed-distance-field glyph sets in PBF format.

"glyphs": "{fontstack}/{range}.pbf"

This URL template should include two tokens:

{fontstack} When requesting glyphs, this token is replaced with a comma separated list of fonts from a font stack specified in the `text-font <#layout-symbol-text-font>`__ property of a symbol layer.
{range} When requesting glyphs, this token is replaced with a range of 256 Unicode code points. For example, to load glyphs for the Unicode Basic Latin and Basic Latin-1 Supplement blocks, the range would be 0-255. The actual ranges that are loaded are determined at runtime based on what text needs to be displayed.

Transition¶

A style’s transition property provides global transition defaults for that style.

"transition": {
  "duration": 300,
  "delay": 0
}

duration¶

Optional Number. Units in milliseconds. Defaults to 300.

Time allotted for transitions to complete.

delay¶

Optional Number. Units in milliseconds. Defaults to 0.

Length of time before a transition begins.

Layers¶

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

Except for layers of the background type, each layer needs to 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.

"layers": [
  {
    "id": "water",
    "source": "sf:roads",
    "source-layer": "water",
    "type": "fill",
    "paint": {
      "fill-color": "#00ffff"
    }
  }
]

Layer Properties¶

id¶

Required String.

Unique layer name.

type¶

Optional Enum. One of fill, line, symbol, circle, fill-extrusion, raster, background.

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.
fill-extrusion: An extruded (3D) polygon.
raster: Raster map textures such as satellite imagery.
background: The background color or pattern of the map.

metadata¶

Optional

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

ref¶

Optional String.

References another layer to copy type, source, source-layer, minzoom, maxzoom, filter, and layout properties from. This allows the layers to share processing and be more efficient.

source¶

Optional String.

Name of a source description to be used for this layer.

source-layer¶

Optional String.

Layer to use from a vector tile source. Required if the source supports multiple layers.

minzoom¶

Optional Number.

The minimum zoom level on which the layer gets parsed and appears on.

maxzoom¶

Optional Number.

The maximum zoom level on which the layer gets parsed and appears on.

filter¶

Optional Filter.

A expression specifying conditions on source features. Only features that match the filter are displayed.

layout¶

layout properties for the layer

paint¶

Optional paint properties for the layer

Layers have two sub-properties that determine how data from that layer is rendered: layout and paint 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. For efficiency, a layer can share layout properties with another layer via the "ref" layer property, and should do so where possible. This will decrease processing time and allow the two layers will share GPU memory and other resources associated with the layer.

Paint properties are applied later in the rendering process. A layer that shares layout properties with another layer can have independent paint properties. Paint properties appear in the layer’s "paint" object.

background¶

Types¶

A Mapbox style contains values of various types, most commonly as values for the style properties of a layer.

Color¶

Colors are written as JSON strings in a variety of permitted formats: HTML-style hex values, rgb, rgba, hsl, and hsla. Predefined HTML colors names, like yellow and blue, are also permitted.

{
  "line-color": "#ff0",
  "line-color": "#ffff00",
  "line-color": "rgb(255, 255, 0)",
  "line-color": "rgba(255, 255, 0, 1)",
  "line-color": "hsl(100, 50%, 50%)",
  "line-color": "hsla(100, 50%, 50%, 1)",
  "line-color": "yellow"
}

Especially of note is the support for hsl, which can be easier to reason about than rgb().

Enum¶

One of a fixed list of string values. Use quotes around values.

{
  "text-transform": "uppercase"
}

String¶

A string is basically just text. In Mapbox styles, you’re going to put it in quotes. Strings can be anything, though pay attention to the case of text-field - it actually will refer to features, which you refer to by putting them in curly braces, as seen in the example below.

{
  "text-field": "{MY_FIELD}"
}

Boolean¶

Boolean means yes or no, so it accepts the values true or false.

{
  "fill-enabled": true
}

Number¶

A number value, often an integer or floating point (decimal number). Written without quotes.

{
  "text-size": 24
}

Array¶

Arrays are comma-separated lists of one or more numbers in a specific order. For example, they’re used in line dash arrays, in which the numbers specify intervals of line, break, and line again.

{
  "line-dasharray": [2, 4]
}

Function¶

The value for any layout or paint property may be specified as a function. Functions allow you to make the appearance of a map feature change with the current zoom level and/or the feature’s properties.

stops¶

Required (except for identity functions) :ref:`types-array`.

Functions are defined in terms of input and output values. A set of one input value and one output value is known as a “stop.”

property¶

Optional String.

If specified, the function will take the specified feature property as an input. See Zoom Functions and Property Functions for more information.

base¶

Optional Number. Default is 1.

The exponential base of the interpolation curve. It controls the rate at which the function output increases. Higher values make the output increase more towards the high end of the range. With values close to 1 the output increases linearly.

type¶

Optional Enum. One of identity, exponential, interval, categorical.

identity: functions return their input as their output.
exponential: functions generate an output by interpolating between stops just less than and just greater than the function input. The domain must be numeric. This is the default for properties marked with , the “exponential” symbol.
interval: functions return the output value of the stop just less than the function input. The domain must be numeric. This is the default for properties marked with , the “interval” symbol.
categorical: functions return the output value of the stop equal to the function input.

default¶

A value to serve as a fallback function result when a value isn’t otherwise available. It is used in the following circumstances:

In categorical functions, when the feature value does not match any of the stop domain values.
In property and zoom-and-property functions, when a feature does not contain a value for the specified property.
In identity functions, when the feature value is not valid for the style property (for example, if the function is being used for a circle-color property but the feature property value is not a string or not a valid color).
In interval or exponential property and zoom-and-property functions, when the feature value is not numeric.

If no default is provided, the style property’s default is used in these circumstances.

colorSpace¶

Optional Enum. One of rgb, lab, hcl.

The color space in which colors interpolated. Interpolating colors in perceptual color spaces like LAB and HCL tend to produce color ramps that look more consistent and produce colors that can be differentiated more easily than those interpolated in RGB space.

rgb: Use the RGB color space to interpolate color values
lab: Use the LAB color space to interpolate color values.
hcl: Use the HCL color space to interpolate color values, interpolating the Hue, Chroma, and Luminance channels individually.

Zoom functions allow the appearance of a map feature to change with map’s zoom level. Zoom functions can be used to create the illusion of depth and control data density. Each stop is an array with two elements: the first is a zoom level and the second is a function output value.

{
  "circle-radius": {
    "stops": [

      // zoom is 5 -> circle radius will be 1px
      [5, 1],

      // zoom is 10 -> circle radius will be 2px
      [10, 2]

    ]
  }
}

The rendered values of Color, Number, and Array properties are intepolated between stops. Enum, Boolean, and String property values cannot be intepolated, so their rendered values only change at the specified stops.

There is an important difference between the way that zoom functions render for layout and paint properties. Paint properties are continuously re-evaluated whenever the zoom level changes, even fractionally. The rendered value of a paint property will change, for example, as the map moves between zoom levels 4.1 and 4.6. Layout properties, on the other hand, are evaluated only once for each integer zoom level. To continue the prior example: the rendering of a layout property will not change between zoom levels 4.1 and 4.6, no matter what stops are specified; but at zoom level 5, the function will be re-evaluated according to the function, and the property’s rendered value will change. (You can include fractional zoom levels in a layout property zoom function, and it will affect the generated values; but, still, the rendering will only change at integer zoom levels.)

Property functions allow the appearance of a map feature to change with its properties. Property functions can be used to visually differentate types of features within the same layer or create data visualizations. Each stop is an array with two elements, the first is a property input value and the second is a function output value. Note that support for property functions is not available across all properties and platforms at this time.

{
  "circle-color": {
    "property": "temperature",
    "stops": [

      // "temperature" is 0   -> circle color will be blue
      [0, 'blue'],

      // "temperature" is 100 -> circle color will be red
      [100, 'red']

    ]
  }
}

Zoom-and-property functions allow the appearance of a map feature to change with both its properties and zoom. Each stop is an array with two elements, the first is an object with a property input value and a zoom, and the second is a function output value. Note that support for property functions is not yet complete.

{
  "circle-radius": {
    "property": "rating",
    "stops": [

      // zoom is 0 and "rating" is 0 -> circle radius will be 0px
      [{zoom: 0, value: 0}, 0],

      // zoom is 0 and "rating" is 5 -> circle radius will be 5px
      [{zoom: 0, value: 5}, 5],

      // zoom is 20 and "rating" is 0 -> circle radius will be 0px
      [{zoom: 20, value: 0}, 0],

      // zoom is 20 and "rating" is 5 -> circle radius will be 20px
      [{zoom: 20, value: 5}, 20]

    ]
  }
}

Filter¶

A filter selects specific features from a layer. A filter is an array of one of the following forms:

Existential Filters¶

["has", key] feature[key] exists

["!has", key] feature[key] does not exist

Comparison Filters¶

["==", key, value] equality: feature[key] = value

["!=", key, value] inequality: feature[key] ≠ value

[">", key, value] greater than: feature[key] > value

[">=", key, value] greater than or equal: feature[key] ≥ value

["<", key, value] less than: feature[key] < value

["<=", key, value] less than or equal: feature[key] ≤ value

Set Membership Filters¶

["in", key, v0, ..., vn] set inclusion: feature[key] ∈ {v0, …, vn}

["!in", key, v0, ..., vn] set exclusion: feature[key] ∉ {v0, …, vn}

Combining Filters¶

["all", f0, ..., fn] logical AND: f0 ∧ … ∧ fn

["any", f0, ..., fn] logical OR: f0 ∨ … ∨ fn

["none", f0, ..., fn] logical NOR: ¬f0 ∧ … ∧ ¬fn

A key must be a string that identifies a feature property, or one of the following special keys:

"$type": the feature type. This key may be used with the "==", "!=", "in", and "!in" operators. Possible values are "Point", "LineString", and "Polygon".
"$id": the feature identifier. This key may be used with the "==", "!=", "has", "!has", "in", and "!in" operators.

A value (and v0, …, vn for set operators) must be a String, Number, or Boolean to compare the property value against.

Set membership filters are a compact and efficient way to test whether a field matches any of multiple values.

The comparison and set membership filters implement strictly-typed comparisons; for example, all of the following evaluate to false: 0 < "1", 2 == "2", "true" in [true, false].

The "all", "any", and "none" filter operators are used to create compound filters. The values f0, …, fn must be filter expressions themselves.

["==", "$type", "LineString"]

This filter requires that the class property of each feature is equal to either “street_major”, “street_minor”, or “street_limited”.

["in", "class", "street_major", "street_minor", "street_limited"]

The combining filter “all” takes the three other filters that follow it and requires all of them to be true for a feature to be included: a feature must have a class equal to “street_limited”, its admin_level must be greater than or equal to 3, and its type cannot be Polygon. You could change the combining filter to “any” to allow features matching any of those criteria to be included - features that are Polygons, but have a different class value, and so on.

[
  "all",
  ["==", "class", "street_limited"],
  [">=", "admin_level", 3],
  ["!in", "$type", "Polygon"]
]
