I am developing an iOS app intended to be used only a specific location (a campus). In this case, I'd like to use ARGeoAnchor to anchor content across a relatively large space, though in the pedestrian-only areas this is not supported and tracking begins to fail.
Is it possible to additionally use ARReferenceObject to re-localize to a specific location when I am walking in an unsupported area. (FB13719373)
Hi Jake!
On iOS I recommend trying to create a WorldMap of spaces where ARGeoTracking is not available. We have some sample code at https://developer.apple.com/documentation/arkit/arkit_in_ios/data_management/saving_and_loading_world_data
World Maps do not supply you with lat/lon locations, but one workaround is to create an anchor in your WorldMap whose lat/lon location is known to you (eg you can look it up in Maps). Please keep in mind that WorldMaps are designed for room-sized experiences, so I recommend only recording a map at specific, confined locations on your campus and only trying to localize against the WorldMap closest to your current location.
