Josh- I wondered. The Lab flew both high and lower rez LIDAR at the same time, effectively looking to the high rez to "train" the lower rez imagery (with realworld groundtruthing of the high rez). One of the telling comments Ken made was, "...for the first time, I'm actually able to see "trees", and "tree parts"...". I've seen the 'flights' and it's a little abstract at first.
