1. A computer-implemented method comprising:
receiving, by one or more processors, a Light Detection and Ranging (LiDAR) scan of a location captured by a LiDAR sensor of a portable device;
processing the LiDAR scan to generate a LiDAR location signature that is representative of the location of the portable device, wherein the LiDAR scan is a point cloud and the LiDAR location signature includes a feature extracted from the point cloud, a subsampling of the point cloud, a crop of the point cloud, or a combination thereof; and
transmitting the LiDAR location signature to another device to share the location of the portable device with the another device.
