+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.
