LIDAR

Kucera International flew their Leica ALS60 LIDAR instrument. This sensor, pulsing at 1064 nm was flown over all sites in the same aircraft as the WASP sensor. The ALS60 is a descrete LIDAR system using a pulsed oscillating mirror configuration. This system has 8 bit of quantization in the intensity channel. It was flown looking at nadir, and had a nominal field of view of 20 degrees, except at theHemlock site, where high topology created a field of view of 12 degrees. This site also had a higher effective ground coverage, with 12 points per meter squared, in contrast to the other sites, which had coverage of 8 points per meter squared.
