LiDAR points and pulses seem straightforward, but the returning signal represents far more. It reflects how the pulse interacts with objects within its footprint, and understanding that interaction is key to interpreting your results.

Point density feels obvious, yet the way LiDAR samples objects shapes what your data can support. Subtle gaps or clusters can change how you read the scene, or mean that smaller objects go unnoticed altogether.

LiDAR range gates limit how far a sensor can measure before pulses overlap, creating ambiguities at high pulse rates and shaping how modern systems handle long‑distance returns.

LiDAR surveys rely on four simple parameters, yet each one shapes how efficiently you capture the world. Together they determine what your data will actually be useful for.
