An app that allowed flying grid pattern to make better 3d models or linear pattern for inspection.
This is an absolute must, in my opinion.
This used to be a feature back in the copilot days airc. Back then, 3d was just getting fleshed out. If proven effective, it'd be a lot easier than flying similar perpendicular missions twice!
This would be a really handy feature for mapping structures and vertical terrain features. I would also like to see something like Pix4D's Free Flight, which lets you fly manually while it automatically snaps a picture every X meters of vertical or horizontal motion.
We just released a Linear Flight Planning beta app on our app market. This is specially designed to map thin and long areas of interest. Try the app and let us know what you think of it.
