Add a georeferenced image | Mapbox GL JS

This example overlays a georeferenced historical image on top of a Mapbox map.

Georeferencing is the process of assigning geographic coordinates to a raster image to define its location in the world based on a map coordinate system.

The georeferenced image used in this example is from a historical map of Portland, Oregon provided by the Library of Congress. You can georeference using a free, open-source tool like QGIS. To learn more, see the QGIS georeferencing tutorial. To use a georeferenced image in a Mapbox map, upload it as a tileset to Mapbox, then add it to your map using addSource.
