In Mapbox services, the
worldview data field is used to identify geographic features whose characteristics are defined differently by audiences belonging to various regional, cultural, or political groups.
|Features for a mainland Chinese audience|
|Features conforming to cartographic requirements for use in India|
|Features for a Japanese audience|
|Features for an American audience|
Some Mapbox vector tilesets, including Mapbox Streets v8 and Boundaries v3, include the
worldview data field in several layers. Those layers may contain multiple versions of some features, each with a
worldview value indicating the intended audience.
When creating a map style with a tileset that uses worldviews, you must apply a filter to any layers that include a
worldview data field. When a worldview filter is not applied, the user will see all possible worldviews at once resulting in conflicting and overlapping shapes.
The value of the
worldview property will either be:
- an ISO 3166-1 country code, for example
allif the feature does not vary between audiences (most features across the world will have a
When you apply the worldview filter, it must include both
all and one of the region-specific values. Additionally, there are classes in respective layers, prefixed with
disputed_, which you must select in conjunction with the worldview filter.
Below is an example filter (using the
get expression) for the
admin-0-boundary-disputed layer in the Mapbox Outdoors v11 style:
[ "all", ["==", ["get", "disputed"], "true"], ["==", ["get", "admin_level"], 0], ["==", ["get", "maritime"], "false"], ["match", ["get", "worldview"], ["all", "US"], true, false] ]
In the Boundaries v3 tileset, the value of the
worldview property can also be a comma-separated list of one or more ISO 3166-1 country codes, (for example
CN,JP). Because a single feature can belong to more than one worldview, you must use the
"in" operator to construct a layer filter. Below is an example filter to enable a US worldview using Mapbox Boundaries v3.
[ "any", ["==", "all", ["get", "worldview"]], ["in", "US", ["get", "worldview"]] ]
