  1. The values presented herein are representative of our instrumentation and our experience to represent sensor quality. The large vertical error is observed with SfM since the displacement between camera perspectives is short in the simulation and is represented of legacy aerial photography. Sample density represents the density of measurements used to update the estimator in this simulation. It does not necessarily represent the density of raw data available from these sensors (such as TLS and ALS)
