Description

Annotations are text, icon or shape graphics on a map that display information useful to users, such as the names of streets, icons for POI data or lines representing a route. Annotations can add a more specific overlay of information to clarify the map to the user.

Currently the SDK supports an annotation API similar to the v6 https://github.com/mapbox/mapbox-annotation-extension. It provides a high level object oriented API that uses style layers and sources under the hood. We expose these APIs to make them more developer friendly and allow developers to write code that treats annotations on a per-object basis.

To have full parity with the v6 annotations API, we need to support two additional features: the annotation view and the callout API. An annotation view synchronises the screen coordinate of an iOS/Android SDK view to a geographic coordinate on the map. A callout displays content (usually text or images) in a popup view above the map, anchored to a geometry.

Android equivalent: https://github.com/mapbox/mapbox-maps-android/issues/418

Research direction

Start by reviewing the existing annotation API described in this issue, the linked v6 mapbox-annotation-extension, and the Android equivalent issue. Define the scope for annotation views and callouts, then verify that both features provide parity with the referenced annotations API.
