User-Side Analyses of the Effect of Laser Data Uncertainties onMapping Applications
Manufacturers’ specifications for laser data acquisition have been used since
the inception of the technology over a decade ago [Habib et. al., 2008; Ussyshkin et. al, 2006].
However, unbiased geostatistical analysis would be valuable in determining – in a pre-analysis stage –
whether or not user-demanded specifications for project-specific mapping applications can be met or
exceeded by the manufacturer’s standards. The partnering organization’s knowledge of false
accuracies, if any, can assess the uncertainty of marrying airborne laser data budgets with the total
uncertainty propagation model [Hare, 2001] – used for hydrographic data error budgeting – in CARIS
HIPS as of now. Ultimately, CARIS seeks to integrate these two error sources and provide a total
uncertainty budget model suitable for both terrain and hydrographic objects.
Finally, assessing the accuracy of LiDAR measurements within a controlled test field will determine
whether or not the actual uncertainties lie within predicted tolerances.
