A cross-reality system enables any of a plurality of types of devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. A cross-reality system may include a cloud-based positioning service that responds to a request from a device to position relative to a stored map. Any type of device having native hardware and software configured for augmented reality operations can be configured to work with a cross-reality system by incorporating components interfacing between a native AR framework of the device and a cloud-based positioning service. These components may present location information about the device in a format identified by the positioning service. Further, these components may filter or otherwise process perceptual data provided by the native AR framework to improve the accuracy of positioning. 交叉现实系统使多种类型的设备中的任何一种都能够有效且准确地访问先前存储的地图并渲染与这些地图相关地指定的虚拟内容。交叉现实系统可以包括基于云的定位服务，该服务响应来自设备的请求以相对于存储地图进行定位。具有针对增强现实操作进行配置的本机硬件和软件的任何类型的设备都可以通过合并
