The Level 2 data from LVIS stores the waveform as cumulative distribution, with the height where various percentage of the return energy are reached.

The 0 height is the ZT elevation recorded. The next value is RH10, fand there is a return every 5%, with addition values for 96 %, 97%, 98% and 99% to tease out the sturcture of the uppermost canopy. | |

The software can tease out an approximation of the actual waveform, with units of percentage of return energy per meter. The peaks here might correspond with the discrete returns from a traditional lidar survey. | |

Mulitple waveforms can be plotted. The differences in the structure will determine how many waveforms can be plotted before the plot becomes impossible to interpret. |
