I can’t speak for the original poster, but for me, I would definitely like to have the ability to pre-plan a flight on a computer with a much more precise mouse than to be forced to use the ipad touch screen."
I completely agree that it would be of great benefit to have flight planning available on a desktop platform. This should also be coupled with a cloud-based sync option. In other words, I should be able to log on to the P4D cloud and see all of my flight data. In this way, someone back at my office can generate a new flight plan and sync it to the cloud. I can then see it in the field and load the new flight plan (assuming an internet connection is present on the device). This would also allow for an option to sync those files with a logging software to keep a running flight log. Multiple crews, using the same P4D sign-in, would all have a central depository for information. This would create a much more efficient workflow between data acquisition in the field, and data processing (cloud/desktop).
Another issue with the software that should be resolved ASAP is the lack of a resume option that would allow me to change batteries without having to start the mission over. At the very least, there should be an option to display previous flights indefinitely so that I know what has been surveyed, and what has not. The previous flight remains visible (assuming the software doesn’t require a reboot) so that the next flight can be planned, but I have not found a way to keep the data visible after the next mission is started.
Speaking specifically to the iOS platform while using the DJI Phantom 4 Pro, if I switch to the DJI app at any point during the mission, no more pictures are taken. The Phantom continues to fly the mission, but does not take any more photos.
Lastly, it would be great if I could plan a flight using existing elevation data, similar to what I can do with the Sensefly platform. At the very least, if I could load a .kml flight plan as a flight line with elevation data (vs a polygon), that would help significantly. I need to be able to fly at a consistent altitude above terrain to have a consistent ground resolution. In areas where there is significant geographic relief, it is difficult to get good data without this ability. This creates a problem when trying to create a bare earth model.
