Error Budget of Lidar Systems and Quality Control of the Derived Data

Integrating lidar, GIS and hedonic price modeling to measure amenity values in urban beach residential property markets

“…Lidar data errors originating from the instrument and the pulse's interaction with the measured surface are usually divided into random and systematic errors (Habib, Bang, Kersting, & Lee, 2009), with the random error more difficult to isolate and control. Within this analysis, site and instrument considerations limit the extent and influence of systematic error but the random error component is uncontrolled.…”

“…The actual horizontal error of the lidar and the GPS combined is likely to be greater than the vertical error but the development of a metric to measure and potentially correct this error are still in the formative stages (Habib et al, 2009). For two reasons, it is assumed that only the random error component of the horizontal accuracy will alter the accuracy of the IPVA° measure and this error would only be in limited areas of topographic obstruction.…”

Point Distribution as True Quality of LiDAR Point Cloud

“…Initial review of a survey area is essential for effective survey planning using existing imagery or maps for a complete assessment (Habib et al, 2009), (Saylam, 2009). Local weather patterns, sudden topography changes, existing water basins, and general terrain cover may impact flight planning and should properly be examined prior to flight planning.…”

“…4 x 50 km 2 ) that should accommodate 20-30% overlapping to prevent loss of data in case of a system failure/reset and easier data processing/handling (Saylam, 2009), where good engines and software are essential for flight planning experts. All these equipment is provided by technical experts, who develop image processing oriented laser scanners (Schnadt and Katzenbeißer, 2004), simulation and data acquisition models (Habib et al, 2008), special targets and related models to improve accuracy and matching procedures (Zhi and Zhong, 2008), etc.…”

“…Accuracy is an issue pertaining to the quality of data and the number of errors contained in a dataset or map (Zhi and Zhong, 2008). Their objects of research are the system of laser scanning, its mathematical models, types and sources of errors, methods and methodologies to improve measurement accuracy (Csanyi and Toth, 2007), (Habib et al, 2008), (Zhi and Zhong, 2008). The technological improvement of laser scanner is developed considering business uses too.…”
