Description

Capturing from https://github.com/mapbox/mapbox-gl-js/issues/9998#issuecomment-705693893 and https://github.com/mapbox/mapbox-navigation-android/pull/3661, the precision of some calculations that affect the presentation of geometries on the map can be greatly improved when EPSG:3857 projection is used instead of turf. We can consider exposing the calculation utils here.

Research direction

Start by reading the linked Mapbox GL JS issue comment and Mapbox Navigation Android pull request, then inspect the repository's existing Turf-related calculation utilities. Done means determining and exposing the EPSG:3857 projection calculations with improved precision, but the issue does not name files or tests to guide implementation.
