68.2% of laser returns are accurate to 1.0'
This is assessed by the laser manufacturer and is a product of flying height (1/3000th of flying height).
Hawaii LiDAR dataset tested .51ft vertical accuracy at 95% confidence level in open terrain, based on open terrain RMSEz (.26ft) x 1.9600; tested .69ft vertical accuracy at 95% confidence level in all land cover categories combined, based on consolidated RMSEz (.35ft) x 1.9600.
Independent accuracy testing was performed by Dewberry & Davis using 80 high accuracy quality control checkpoints distributed throughout the project in four major land cover types (open terrain, weeds/crops, forest, urban). Dewberry used testing procedures consistent with those specified in the National Standard for Spatial Data Accuracy (NSSDA) as well as LiDAR accuracy testing guidelines and specifications published by the Federal Emergency Management Agency (FEMA), National Digital Elevation Program (NDEP), and American Society for Photogrammetry and Remote Sensing (ASPRS).
