This is the plane and Equipment Woolpert is using to fly our LiDAR acquisition this fall. The following is a thumbnail sketch of the acquisition process: * 272,000 pulses per second is our pulse rate spec for this job. * Scan pattern is "Triangle" in Leica terminology but yes that could be a called a zig/zag. * Using our most recent mission we were actually "on-line" a total of 120 minutes. (i.e. With the sensor actually firing, not while turning at the ends of lines nor flying to the lines) * 272,000 pulses x 60 seconds x 120 minutes = 1,958,400,000 pulses in that mission, and there can be 2 or more returns per pulse depending on what type of area we are in (pavement, forest, field, etc.) o Furthermore that mission with only 120 minutes on-line time is actually on the low side of what we can do if the weather allows us. o The total capture for this project will be many billions of points * [cid:image001.png@01CEE053.A1B71240] Operating station [cid:image012.jpg@01CEE072.F2809650] Sensor unit [cid:image013.jpg@01CEE072.F2809650] Sensor well [cid:image014.jpg@01CEE072.F2809650] Sensor (not the white pebbly area) but where the arrow is pointing on the yellow tag.
