iOS uses CLLocationDegrees which is a type alias for double precision.Using ARKit, let’s check our tech stack to see if we have the precision we need: Mapbox Unity SDK makes it easy to get started with geospatial applications using ARKit and ARCore. So if we need sub-meter accuracy, we need to exercise care. # East/West at 45 N/S (it gets worse at the equator) If we encode latitude and longitude data using single precision floats, we can expect to be off. Consumer phones and tablets’ GPS units are not particularly accurate, so this is often not a concern. Some geospatial applications need precision. ![]() AR provides an intuitive interface to navigate and understand the world in 3D. AR is a particularly interesting technology when combined with geospatial.
