Service Description: The 1955 waterline for the Barrow region was created from a black and white orthophotomosaic with a pixel resolution of 1.3 m (4.3 ft), produced for this project from US Air Force aerial photographs taken August 12 and 14, 1955. The 1979 waterline was digitized from a color-infrared orthophotomosaic with a pixel resolution of 1.7 m (5.5 ft), crafted by the Alaska Satellite Facility for the Arctic LCC using AHAP photography dated July 15, 1979. The 2002 waterline was digitized from Digital Globe QuickBird panchromatic satellite imagery at 0.7 m (2.3 ft) resolution dated August 1-2, 2002, where available, and elsewhere from orthorectified radar imagery (ORRI's) at 2.5 m (8.2 ft) resolution acquired July 27-29, 2002. Finally, the 2014 waterline was digitized from a pan-sharpened color-infrared mosaic of Digital Globe GeoEye-1 and WorldView-2 satellite imagery, processed by E-Terra LLC for the Ukpeagvik Inupiat Corporation (UIC), at 0.5 m (1.6 ft) resolution from scenes collected on July 25, August 10-11, and September 6, 2014
