Cool science project! A few more thoughts and ideas....:
1. Have you looked at the drone's APIs and on-board control features? If it has any digital I/O features, you may be able to control the K-1 from the ground through the drone's API with a simple bit of electronics, and the wired remote port on the camera. And if that doesn't work, then a long-range wireless remote control can do that job.
2. Time lapse could work if you program the drone to fly to a grid of locations at set time intervals and hover in sync with camera's time lapse. (Note: you are probably going to want to program the drone to fly a fixed grid for the survey and sensor shots anyway so that your scans are comparable over time.)
3. Wifi range will be curtailed and unreliable if there is any vegetation between the drone and the base station.
4. AF may not work well in UV or IR. But manual focus should be workable for your project even at f/1.4. For example, if your goal is to image a 10 m x 15 m rectangle with each shot (= a pixel size of 2mm on the ground), you'll be flying at about 20.8 m above ground level. If you set a 50 mm f/1.4 lens to focus at 16 m, then everything from ground level up to about 10 m up should be in focus. You can use a DoF calculator (
Depth of Field (DoF) calculator | PhotoPills) for other scenarios.
5. You'll probably want to do some experimentation with lenses to check the plane of focus, aberrations, and transmission in UV and IR.
I look forward to hearing more about your project!
