helikite aerials

Hi all,

I'd promised to post a few of these aerials, so I hope this upload works. These are taken using my GRDIII attached to the Skyshot model, a 1.6 cu.m. helikite (combines the best of a kite and a small helium-filled balloon). Altitude is typically 15-30 m above ground level. I've been concentrating on verticals (planimetric) to study stream dynamics, but the obliques are interesting too.

Very interesting! Just looked up on your kite model on the web, great concept. For the first gigapan you posted, did you have to tow the helikite along the stream, or were all the shots taken from one or a few vantage points?
Do you know of any farm applications anyone is doing?
Thanks!
 
Thanks for the good feedback, questions and kind comments. A few things:

- I had placed an example of the 'mosaic' stitched version of these images -- I call them 'helipans' -- in the "Guess What it Is" forum. For a quick link to the GigaPan.org website where 5 or 6 helipans are lodged, go to that website and enter "helipan" into the search box.

- Petach: stability isn't really an issue. Only about 1 out of 10 shots, let's say, is a little blurry when there's a gust of wind and the helikite wobbles, or I jerk the line. I do avoid gusty days; a steady light wind, or no wind at all, is best. And the GRDIII is wonderful and sharp; the 1.9 lens means one can keep a fairly fast shutter speed even on overcast winter days, as on the day I took the images above. I do tweak the exposure and levels a bit to brighten, but there's no problem with sharpness.

- Quester: both single vantage point 'panning' and 'towing' work for different applications. Generally, I like a combination of the two: tow the helikite to a good vantage point, stop, sort of wobble it a little so that it pans, then move to the next spot, ensuring 30-40% overlap, then stop and pan a bit more. Constant towing is less reliable because it can result in gaps where the one or two photos needed to ensure good overlap happen to be fuzzy because you're walking along a bumpy landscape and jerking the line. Also, yes, I have done some earlier helikiting on ag. lands, but with an older Konica/Minolta point-and-shoot (lousy camera). I haven't done any real agricultural analysis -- more just orientation, reconnaissance and outreach communication.

I'll check my cache and see if there might be a few more interesting photos worth posting.

Here are a few more shots, including a 'farm'. Actually, the farm complex is now a nature center, but the barn is an original forebay bank barn of the type that defines the Pennsylvania culture region -- rural architecture introduced some 200 years ago by settler immigrants from the Germany-Switzerland border region.

Thanks, Ken, for the replies.
Looking again at the Allsopp Helikite site, I see that they also have a model to scare birds from an area, which could lessen damage to crops or orchards (they even guarantee this for two months)...food for thought.
In any case, quite a nice hobby to get a bird's eye view without all the risks...
 
These look very cool :cool: . Must be a great deal of skill involved in getting pictures like this :mrgreen: . I don't see these sort of pictures every day, that's for sure ;) .
 
These are great images. Nothing can beat a vantage point. It does take some of the flatness out of an image with a little height.
