Chris this is great stuff. Glad it was you who beat us to this goal :) Can you post some KML Ground Overlays for this data so we can have a look at the full set of data? Which Digital Elph are you planning to use next time?

Where next?

I don't know much about UAVs, but when I was in Austin studying aero eng. in the mid-80s, across town Lockheed was spending a lot of $$ trying to build the Aquila, which was ultimately cancelled.

That UAV was going to cost upwards of a million dollars a piece, and they were having lots of problems, especially with recovery, if I remember correctly.

I know you've got the benefit of a quarter century more development of sensors, etc., and a much simpler "mission", but I can't help but think how hobbyists like you could have saved the federal govt. a lot of money!

The Israelis were having much better success at the time, making simpler aircraft that didn't break the bank when they were lost. The Air Force & Army still seem stuck mostly on big expensive stuff, but I hope someone there is checking out your DIY Drones site!

The history of American UAVs is a good case study in how it pays to prototype early and often, which I guess hobbyists are a lot better at.

"What you're actually seeing in my images are the blue pool covers, not the water itself. But I walked over and lifted them up to confirm that the logo isn't there. Ground truth!" Yep!

But ... "Plus there's those rooftop laser cannons" ... you ARE just kidding, right?!!

what about muliple cameras (2 or 3) triggered in a staggered sequence?
would that weigh down the plane too much?



The problem with the motion blur is because your shutter speed is too slow, and nothing else. I would say 1/500th of a second would be a good starting point. Also there are many digital slr's such as any in the canon 1d series which are able to shoot up to 8 frames a second, though they may be too heavy for your aircraft. Good luck.
