That's true, though it depends on the size of the balloon. You could also hang it off a kite or R/C plane though again that's additional cost/complexity.
Really though, for many gardening folks, an oblique handheld shotis fine. It'll point out the areas in their garden that need help. It doesn't necessarily have to be photogrammetric. A live view could come in handy here. Just scan around your garden and see where it needs help. - bri On 5/24/13, Eric Wolf <[email protected]> wrote: > One of the challenges is to work up a camera that can capture the IR image > fast enough.
