Down the dirt road a ways.
Hello, fellow drone meisters. I am dabbling in the dark art of flying grid mapping missions using Litchi with my older Mavics to create a 2D ortho-mosaic image by later" stitching together" all the photographs taken at 5-second intervals along the drone's "lawn mower flight path."

To keep the waypoint count down below 98, I am trying to find a way to batch-delete all waypoints EXCEPT those that lie at the ends of each lawn-mower pass of the drone, at the point where the drone makes an about turn to fly in the opposite direction. I found that by simply batch-deleting waypoints, without having a means to set those end-point waypoints as "read only" so that they are not allowed to scoot over to "fill the gaps" that appear as I batch-delete non-essential waypoints, that shifting of waypointws as I delete others has the effect of deforming the flight path at those end-points, which I would rather did not happen.

So, my question is whether any of Litchi's more experienced users can describe the steps needed to fix specific Litchi waypoints at their current GPS location, as a prelude to deleting numerous other non-essential waypoints that lie along the flight path between the end-points of each lawn mower pass of the drone. Any advice that can be offered in this regard would be greatly appreciated. As a footnote, I plan all my Litchi missions on the Litchi Flight Hub, and never on a mobile device. Thanks in advance for any pointers that can be offered.
 
I can’t help with the mass delete. If you are doing “lawn mower” passes, look at DroneDeploy. The software to capture the images, I believe is still free. It is designed to do (I think), what you are trying to capture. DD charges you if you submit the images for them to stitch.
You can also take a look at DJI’s GS Pro to see if it may meet your needs. I used that a lot with my Mavic Pro back in the day. Also used it with M2 Pro until the RID update.
 
I thank you kindly PHZ, for this mention of Drone Deploy. I had in the past regarded Drone Deploy as being too pricey for my limited means, so it is a surprise to read this mention you have made that the aspect of Drone Deploy that is required for creating the lawn mower flight path might be free.

I posed this same question at the Litchi forum, where the predicament I described was solved in a simple yet elegant way that entailed the selective mass deletion of superfluous waypoints, using a method that did not distort the shape of the flight path. I will include the link to those educative responses at the Litchi forum for the benefit of anyone who runs into a similar problem of trying to keep the waypoint count of a mapping flight below 99.
