Frequently Asked Questions

  1. Question: what happens if I run out of free space on the memory card while recording data (ALS or MLS)?


    Answer: recording files to the memory card will stop, but recording to internal memory will not start. No further shooting data will be recorded. It is recommended that you check the remaining space on the memory card in advance and clear it if necessary. 

  2. Question: Why is it recommended for MLS to use electric transportation: scooter, scooter, etc. for TOPODRONE BackPack?


    Answer: to reduce vibrations, wave-like surges (in human gait) and a smoother overall trajectory. 

  3. Question: Why is it recommended that a ALS or MLS session not exceed 30 min?

    Answer: it has been experimentally determined that when the ALS data recording time exceeds more than 30 min. 

     

  4. Question: Topodrone LiDAR does not download data to the external flash drive after writing data to the internal memory.


    Answer: it can be one of the following reasons:

    a) When connecting an external drive to the USB Type-C connector, make sure that the external drive is properly (all the way) connected to the USB Type-C port of the Topodrone LiDAR. If you are using a USB OTG adapter, make sure it is correct.
    b) The TOPODRONE LiDAR has not been initialized before being prepared for use for ALS or MLS. For example, due to an unconnected external antenna cable or insufficient GNSS signal quality. Even if GNSS data is lost during ALS or MLS, the data set in the internal memory of the Topodrone LiDAR will still be generated and available for download.
    c) The data from the Topodrone LiDAR has already been previously overwritten and deleted from the internal memory after a successful transmission.

  5. Question: is it nessesary to perforn an infinity or front-back calibration maneuver every ALS or MLS session?
    Answer: yes, calibration maneuver must be performed every time before the main area survey starting.
