Service Description:

LIDAR-derived binary (.las) files ASPRS ver 1.4 format containing classified points of all returns. We have 11 classifications Unclassified, Ground, Automated Low Veg [0.5-5 feet] , Automated Medium Veg [5-20 feet], Automated High Veg [20 feet], Automated Buildings, Low Noise, Water, Bridge Decks, High Noise and Ignore Ground (breakline proximity). Model key points are bit-flagged and created from ground (class = 2) points using a five foot horizontal and a 0.2 foot vertical variance. The files are delivered in 2000ft by 2000ft tiles. These files adhere to the USGS-NGP Lidar Base Specification, Version 2.1 Quality Level 2 (QL2) standards. The contractual aggregate nominal pulse spacing (ANPS) is less than or equal to 0.5m. The contractual aggregate nominal point density (ANPD) is 4.0 points or greater per square meter.
