| ### The Mapbox Standard style | ||
|
|
||
| We're excited to announce the launch of Mapbox Standard, our latest Mapbox style, now accessible to all customers in a beta version. The new Mapbox Standard core style enables a highly performant and elegant 3D mapping experience with powerful dynamic lighting capabilities, and an expertly crafted symbolic aesthetic. | ||

The new Mapbox Standard core style enables a highly performant and elegant 3D mapping experience with powerful dynamic lighting capabilities, landmark 3D buildings, and an expertly crafted symbolic aesthetic. | ||
|
|
||
| With Mapbox Standard, we are also introducing a new paradigm for how to interact with map styles. When you use this style in your application we will continuously update your basemap with the latest features with no additional work required from you. This ensures that your users will always have the latest features of our maps. You can get more information about the available presets and configuration options of the Standard style in the style documentation. | ||
|
|
||
| * The Mapbox Standard Style is now enabled by default when no `style` option is provided to the `Map` constructor. Or, you can still explicitly set the style by passing the URL to the `style` option of the `Map` constructor. | ||

|
||
| * The Mapbox Standard style features 4 light presets: "Day", "Dusk", "Dawn", and "Night". The style light preset can be changed from the default, "Day", to another preset with a single line of code: | ||
| * The Mapbox Standard Style offers a dynamic way to personalize your maps. The map's appearance can be changed using the `map.setConfigProperty` method, where you reference the Standard Style as `basemap`, followed by the configuration property, like light preset or label visibility, and then specify the desired value. | ||

| ### Custom data layers | ||
|
|
||
| Mapbox Standard is making adding your own data layers easier for you through the concept of `slot`s. `Slot`s are pre-specified locations in the style where your layer will be added to (such as on top of existing land layers, but below all labels). To do this, we've added a new `slot` property to each `Layer`. This property allows you to identify which `slot` in the Mapbox Standard your new layer should be placed in. To add custom layers in the appropriate location in the Standard style layer stack, we added 3 carefully designed slots that you can leverage to place your layer. These slots will remain stable, so you can be sure that your own map won't break even as the basemap evolves automatically. | ||

These layers are rendered underneath symbols, regardless of whether they are placed in the `middle` or `top` slots or without a designated slot. | ||

| Like with the classic Mapbox styles, you can still use the layer position in `map.addLayer(layer, beforeId)` method when importing the Standard Style. But, this method is only applicable to custom layers you have added yourself. If you add two layers to the same slot with a specified layer position the latter will define order of the layers in that slot. | ||
|
|
||
| Standard is aware of the map lighting configuration using the `measure-light` expression, which returns you an aggregated value of your light settings. This returns a value which ranges from 0 (darkest) to 1 (brightest). In darker lights, you make the individual layers light up by using the new `*-emissive-stength` expressions, which allow you to add emissive light to different layer types and for example keep texts legible in all light settings. If your custom layers seem too dark, try adjusting the emissive strength of these layers. | ||
|
|
||
| ### Customizing Standard | ||
|
|
||
| The underlying design paradigm to the Standard style is different from what you know from the classic core styles. Mapbox manages the basemap experience and surfaces key global styling configurations - in return, you get a cohesive visual experience and an evergreen map, always featuring the latest data, styling and rendering features compatible with your SDK. The configuration options make interactions with the basemap simpler than before. During the beta phase, we are piloting these configurations - we welcome feedback on the beta configurations. If you have feedback or questions about the Standard beta style reach out to: [[email protected]](mailto:[email protected]). | ||
|
|
||
| You can customize the overall color of your Standard experience easily by adjusting the 3D light settings. Individual basemap layers and/or color values can’t be adjusted, but all the flexibility offered by the style specification can be applied to custom layers while keeping interaction with the basemap simple through `slot`s. | ||
| When using the Standard style, you get the latest basemap rendering features, map styling trends and data layers as soon as they are available, without requiring any manual migration/integration. On top of this, you'll still have the ability to introduce your own data to the map and control your user's experience. If you have feedback or questions about the Mapbox Standard style reach out to: [[email protected]](mailto:[email protected]). | ||
|
|
||
| Our existing, classic Mapbox styles (such as [Mapbox Streets](https://www.mapbox.com/maps/streets), [Mapbox Light](https://www.mapbox.com/maps/light), and [Mapbox Satellite Streets](https://www.mapbox.com/maps/satellite)) and any custom styles you have built in Mapbox Studio will still work like they do in v2, so no changes are required. | ||
|
|
||
| ### Lighting API | ||
|
|
||
| The new Standard style and its dynamic lighting is powered by the new Style and Lighting APIs that you can experiment with. The following experimental APIs can be used to control the look and feel of the map. | ||
|
|
||
| In GL JS v3 we've introduced new experimental lighting APIs to give you control of lighting and shadows in your map when using 3D objects: `AmbientLight` and `DirectionalLight`. We've also added new APIs on `FillExtrusionLayer` and `LineLayer` to support this 3D lighting styling. Together, these properties can illuminate 3D objects to provide a more realistic and immersive map experience for your users. Set these properties at runtime to follow the time of day, a particular mood, or other lighting goals in your map. | ||
