They seem to be careful not to show a large object like a plane crossing the "seams" that appear in the video (similar to the seams in satellite imagery on maps where they've patched together data from multiple passes / satellites). When you see the cars on the freeway they seem to disappear at the seams. Does the camera have to be focused on an area the size of the blocks they show? This is still very impressive - I don't mean to downplay the technical achievement, but I'm just trying to get a realistic sense of where the technology is at. I suspect this is video overlaid on static images.
- celoyd 13y agoThe video field of view is 1.1 by 2 km: http://skybox.com/uploads/10/08/imageryandvideospecsheet.pdf http://skybox.com/uploads/10/08/imageryandvideospecsheet.pdf Purely speculating, not going on anything they’ve said: theoretically when they have more satellites you might be able to patch together a larger area with simultaneous video from several birds. You’d have a slightly ugly angle difference at the seam, of course. There may be technical constraints here that I’m not thinking of, though. In any case, at 1 m GSD and 30 fps, 1.1 by 2 km is 66 megapixels a second. Even efficiently compressed, that’s a lot of information already.

- sixothree 13y agoIt looks more like the fov is 0.1 by 2 km (in this particular video).
- omegant 13y agoIt seems like the part of the image showing the video is surrounded by pictures (not video). It seems everything is video because he is moving the image around just at the right time. A cool technology enanced with a cool trick.
