PulseWaves is a new exchange format for full waveform LiDAR data. Below you see a simple visualization of a small sample of full waveform LiDAR data exported from RIEGL’s RiProcess to the PulseWaves format via a prototype of the PulseWaves DLL interface.
Illustrated in 3D are the waveforms of 50 pulses via a green to red shading of their intensity. Plotted in more detail in 2D from left to right are the waveforms of a single pulse that is in the very center of these 50 pulses. The outgoing waveform is red. The returning waveform – in this case consisting of two segments – is blue.
The 3D points (here mostly yellow apart from a few orange and blue ones) correspond to the first recorded waveform sample of each pulse. Through them a particular pulse (or a set of pulses) can be picked by pressing the ‘i’ hot key in the interactive 3D viewer – pulseview.exe – when hovering over a point. The color coding of these points indicates that different pulse descriptors are used for describing the waveforms of the corresponding pulse.
