Virtual Litchi Missions in Google Earth

This post has been superseded – see the new way to create Virtual Litchi Missions here


In today’s blog, I will share a short video showing how to run Litchi missions in Google Earth to show exactly what they will look like before you get on location and start burning precious battery time.

This is an amazingly powerful tool that if used correctly, can make you look like a superstar.  You can do almost all of the mission planning from the comfort of your own home, then turn up on site, get the shot and leave.  This means much less standing around in the cold tweaking while the client looks over your shoulder.

You’ll need two pieces of software for this to work:

I’ll let the video do the talking here.  But if you have any questions please feel free to post in the comments below.

We have talked about this before here but I really wanted to show how to set it up.

  2. Are we still limited to 99 waypoints? Not so good for curved flight lines which a) give you a superior diversity of views and b) mitigate the systematic SfM doming (elevation) error – especially when oblique imagery is included. Refer to the following independent research:

    Results of the simulation process, the laboratory test and the practical test are reported in this paper and demonstrate that an oblique convergent image configuration eradicates the systematic error surfaces which result from inaccurate lens distortion parameters. This approach is significant because by removing the need for an accurate lens model it effectively improves the accuracies of digital surface representations derived using consumer‐grade digital cameras. Carefully selected image configurations could therefore provide new opportunities for improving the quality of photogrammetrically acquired data.

    Thanks for a super easy to follow video. Got it quickly the first time following your instructions ?

    1. Thanks! Glad I could help.

      I do actually need to do a new version of this video at some point, because there is an even easier way to do this now. But this method still works and actually has a few advantages.

      1. Hi Barry
        Many thanks for all this info.
        Can you please elaborate on why this version has advantages over the new method with google earth?

        Also, I too love doing golf course flyovers but cannot trust the auto height settings in Litchi ‘AGL’ settings, tried to fly a 20/30 feet AGL and almost ploughed into the fairway ! Any advice please?

        1. Hi Ian,

          The original method does produce a useful graph at the bottom that shows information about altitude relative to the ground, which can be useful when planning to help identify incorrectly set waypoints or problems that might arise from large hills etc. But, since the Chrome plugin added the ability to select your drone to set the FOV, I use that 99.9% of the time.

          As for golf courses. You are correct. AGL will get you close, but you must run it on site as a test to make sure that things are safe before doing the run to actually capture video. This is especially true if you come down for a close up of the hole, which my videos typically do. It’s part of what makes the golf courses so time-consuming, especially on public courses that never close so you are continually dodging players to get a clean shot.

          Some examples of dropping down can be seen here:

          Thanks!
