I've recently been researching terrestrial 360° cameras for myself. Which make and model of 360° camera are you using, and which cell phone app do you use it with?
As to aerial 360° panos from the drone, GO 4 already has a terrific fully automated Spherical Pano function under the camera settings (available under the single shot selection, as one of many alternatives), which even fills in ceiling of the sky for you, saves the stitched 360° pano to the microSD card, and even saves the originals, too, if you choose that option, in either jpg or DNG (can't do both, unfortunately). It's available on the Mavic 2 Pro, Mavic 2 Zoom, and the P4P, and probably others as well. Takes 60 seconds per pano, leaving plenty of flying time in between panos to move around to different locations. I've managed as many as 8 panos and 13 minutes of video in a single flight! I then use PanoramaStudio 3 Pro to create the interactive web output, from either the lower resolution microSD card stitch, or the original 25 .jpg images, for the best quality. It also supports visually chaining panoramas together, like yours above, and even plotting them all together on an interactive Google Map, along with an optional thumbnail gallery of panoramas along the bottom, and an optional compass for the changing view heading, while scrolling around within the image. Way cool, and highly recommended!
Tobias is also very responsive and helpful with any and all questions.Create and present 360 degree panoramas | PanoramaStudio Panorama Software

Before I answer the former, let me sincerely THANK YOU for the latter! I have shot a few 360º panos with the Mavic (we have the original, not the 2nd round) and I'll be darned if I could figure out how to put them together. I tried a few options and ended up with frankensteined rejects so I just gave up. Thankfully BEFORE I threw the computer through a window. ha. I will for sure check out the link you shared, especially because we have round 2 of a resort shoot in a few weeks, and I would love to be able to shoot a few 360º panos for them from the air! We will be shooting their cabins with the 360º cam we have, so this would work perfectly. I think he might pass out at "Interactive Google Map" if I could figure THAT out! Plus, it sounds like the software might do a lot more for us - I've not been happy with the "all or nothing" manner of "you can either view these in one window and use the hot spots OR have a gallery." I really like the idea of having both as an option for the viewer. Thank you so much! I hope Tobias gives you a kickback! haha.
Ok, so on to our 360º cam. We have the Insta360 OneX, and it has a proprietary app. So, so, so ridiculously easy to use! With the exception of setting up the hot spots to jump from one place to the next, I did next to nothing for these photos. Shot them, let the software figure out the HDR processing, and that was it. It's almost embarrassing how easy it is (coming from the "old school" process of bracketing photos and combining in Photoshop with custom layer masks, etc.) We spent almost as much on the special monopod from Europe, but boy is it NICE! It requires very little PS-ing out of anything in the photo. Just a tiny bit of 3 legs, which is usually just taken care of with 30 seconds using the clone tool. You get smarter about where you place it, when you know the work involved in removing it.
