Abstract
The point density is a preeminent parameter on airborne laser scanner surveys. It is not only related to accuracy but costs and savings. The lack of uniformity of the point density across the survey is well-known in the scientific community. This paper analyzes the behaviour of the point density derived by an oscillating mirror laser scanner on different single strips on flat bare ground in order to estimate a meaningful mean density value. The variation of the point density at both extreme ends of the oscillating mirror scan is meaningful. It will be demonstrated that excluding the extreme sectors across the strip corresponding to 1/8 of the swath width (12.5% of the sampling area, half in each side) for the computation of the mean density value is enough to satisfy light detection and ranging (LiDAR) specifications for national level surveys.
