On Android/ARCore Geo Trackables are supported with Google Geospatial Anchors.



Geospatial Anchors are anchors that are hosted on the ARCore API cloud endpoint. This hosting enables users to share experiences in the same app using GPS and Google Earth data: see https://developers.google.com/ar/develop/geospatial



For using ARCore Geospatial Anchors you need to:

* Add the the arcore unity extensions package as a dependency of the Unity project  https://github.com/google-ar/arcore-unity-extensions

* Add to the runtime asmdef of this package a reference to Google.XR.ARCoreExtensions.asmdef

* Add a new Script Define Symbol in the Unity project settings: "ETSIARF_ARCORE_EXTENSIONS"

* Then, follow the instructions detailed here https://developers.google.com/ar/develop/unity-arf/geospatial/enable-android and here  https://developers.google.com/ar/develop/authorization?platform=unity-arf to configure the project and your google cloud account



To use a Geo Pose Trackable that corresponds to a Google Geospatial Anchor, the payload of the Trackable in the World Storage must be an array of doubles following this format : [latitude, longitude, altitude, rotationX, rotationY, rotationZ] in base 64.
