Several factors could cause no points to be added to the point cloud.
- Do PCAP file sizes look okay?
- Should be tens or dozens of MBs (for all but first and last file, which may be shorter)
- Are PCAPs from the correct flight?
- With Velodyne LiDAR you can investigate the GPRMC message in Wireshark, use an online GPRMC decoder, and see the time and position of the packets and compare to the trajectory.
- GRYFN Processing Tool logs should also give an indication of the times not aligning to the trajectory.
- Could not retrieve an EOP for timestamp:
- Are the minimum and maximum laser ranges inclusive of the required point distance from the flight?
