One of the advantages to RC video/still shots is that you can get any angle on the area you want. For instance, I can fly at low elevation past a wood line and spot any opening in the canopy on the side of that wood line that might indicate an old trail opening, where as from above the tree branches/canopy might not indicate such an old trail once existed. Also, the lower angles you can view stuff at can show slight depressions or raises in the ground level to tip you off to an old foundation site or such. Despite all the great advantages to satelite (which I use too of course) images, I don't think (?) they are able to show you slight raises in the ground even when you flip the perspective sideways because it's still a picture. Even with radar images I'm not even sure if public access stuff could show you say a 3" rise or depression in the ground height from that surrounding it. I'm not knocking satelite stuff because I use it myself to scout out areas I have no intention to fly an RC plane over, but if something really interests me I can come back later and fly over with the RC and take a closer look.
You know, one of the things I have intended (but haven't done yet) to do with the RC aerial stuff is to fly over some of my hunting land on a huge expanse of old strip mine land. There are hundreds of pounds all over that place tucked away by steep cliffs and mazes of logging roads and such. Even if you spent weeks hiking around to locate many of these pounds, from one year to the next beavers make new ones or abandon dams and pounds dissapear. A quick 15 minute flight over an area and I've have up to date information on where pounds are at that would take me months to find. One of these days I'm going to do that, because the fishing is fantastic and we also jump shoot ponds for ducks and geese there. It would be nice to throw a DVD into the TV the night before and watch an RC aerial video of the place and find new ponds to jump shoot, and pick out strategies as to the best way to sneak up on them using natural blinds such as the cliff faces that are often nearby.
Some day I'm going to do that. I can launch and land my AP plane on any old dirt road wide enough to drive down, although I prefer a bit wider landing strip for peace of mind and room for mistakes. Great thing about foam though is it glues together fast. I've got these planes so crash proof with carbon spars at Tyvek tape and such anyway that they'll take a rather bad crash without damage. That's why I prefer push planes, because if they nose into the ground no damage is really done most of the time.
