Live Stream – LP360

The Live Stream tool in LP360 displays and records LiDAR data in real time from supported TrueView payloads or replays previously streamed data for review. It is commonly used for field verification, sensor checks, and validating coverage during flight.

A TrueView payload capable of LPLAS live streaming (e.g., TrueView 515vB with live stream firmware)
Computer connected to the payload’s network
Correct IP addresses and port configuration for the payload
Optional: LPLAS stream files for Replay mode
