The NASA IceBridge UAF Lidar Scanner Level-1B Geolocated Surface Elevation Triplets (ILAKS1B) data set contains scanned altimetry points of Alaska Glaciers acquired using the airborne University of Alaska Fairbanks (UAF) Glacier Lidar system. The data were collected as part of Operation IceBridge funded aircraft survey campaigns, and are stored in American Society for Photogrammetry and Remote Sensing (ASPRS) LASer (LAS) 1.2 sequential binary format and are available for periodic, ongoing campaigns from 19 August 2009 to the present via FTP.
