I was going to reply to this earlier but didn't get to it immediately and now I've been gone for a few days. Just had a conversation on IRC that reminded me of this topic. I do have some videos that might be of use to you. They are time-lapse videos that I made using a GoPro camera mounted on my bicycle on some longer rides. Pictures were taken at 5 second intervals and then stitched into a 10 fps video. Any given sign is only going to be visible for maybe 2-5 frames, depending on how fast I was going. The videos are on youtube in 1080p, under a CC license so I think it should give you the option to download to a .mp4 file for local use. I also still have the original 11 megapixel stills if that would be of help. The two videos are here: http://www.youtube.com/watch?v=Q8I7H8qwtqI http://www.youtube.com/watch?v=h43tsSNqYRA I also have a shorter ride in the city that I did in full motion video with the camera mounted on my helmet and then sped up. It is kind of shaky. I could supply the original speed video if that would help. I believe it is only 720p. http://www.youtube.com/watch?v=pJ_OkzGBoek I'm doing Bike Across Kansas next week so I will probably be posting more similar videos in the future :) Toby _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
