The snow cover is computed for the region Central_area, covering parts of region 2 in the map in: GeoBasis_Zack_Snow_properties_Central_area_Snow_cover.pdf. The corners of the area are ,
NW: 8266470 mN, 512815 mE,
NE: 8265710 mN, 514625 mE,
SW: 8264495 mN, 512765 mE,
SE: 8263505 mN, 515000 mE,
(WGS 84, UTM 27N)
The area covers 3.6 square kilometres. Snow cover is computed from orthorectified digital photos taken from the slope of Zackenberg, ca. 480 meters above sea level. The cameras used to capture the digital photos were: 1998 - 2005-06-30: Kodak DC50, 2005-06-30 - 2008-05-03: Kodak CX 6200 RDC 365, 2008-05-03 - now: HP Photosmart E427. The images are captured every day at 13:20, which is solar noon in the Zackenberg valley. Snow cover data from 2003-2005 is missing.
