Title: Colorized airborne lidar point cloud dataset for areas near Toolik Field Station, Alaska, 2013 DOI: 10.60841/000000266 Description/Abstract: Colorized point cloud data were derived from discrete return airborne lidar data and orthophotography that were collected simultaneously on August 1st, 2013 at five discrete areas near Toolik Field Station in northern Alaska. The lidar sensor was a Riegl VQ-480i operated at a nominal altitude of 366 m AGL and +/-60 kn. Vertical accuracy was estimated at 8-10 cm. Nominal collection density was 13.5 points per square meter with ~60% sidelap to yield an aggregate density of ~27-30 points per square meter. Imagery sensor was a Leica RCD30 60MP medium format digital camera collecting 4-band RGBN data. Imagery pixel resolution was 0.052 m. Data projections are: NAD83 UTM Zone 6N (horizontal, meters); NAVD88 Geoid 12A (vertical, meters).
