# source

A **source** supplies the data that displays on a Mapbox map. Sources are defined by the [Mapbox Style Specification](https://docs.mapbox.com/style-spec/reference/sources/), and are used with [style layers](https://docs.mapbox.com/help/ja/glossary/layer/) to visually represent the source data on to a map. Specific source types may not be supported depending on which platform you're developing on, so refer to [platform-specific documentation](https://docs.mapbox.com) when adding sources to your map.
