Try DJI GS Pro. It doesn't say it supports Spark, but it does. I used it to plan and execute several mapping missions. Make sure to orient the camera/gimbal to nadir manually before starting the mission; it took me a while figure this out :)
Hi,
I just bought a DJI Spark and I am interested in doing some mapping/photogrammetry. It seems that DJI's app doesn't support that kind of mission planning. I am considering buying Litchi. Can I use to plan picture taking missions for photogrammetric use?
