Aerial photo maps of snowy ground (SnowEx 2023)
What it measures. Aerial photographs of snow-covered ground in two parts of Alaska, taken from an airplane to map the landscape.
How it's made. Captured as airborne photogrammetry images during NASA's SnowEx 2023 field campaign over a boreal forest near Fairbanks and coastal tundra on Alaska's North Slope.
How & where you'd use it. Used by snow scientists to map and study snow-covered terrain in forest and tundra environments in support of snow research.

Official description
This data set contains aerial photogrammetry images collected from two regions of Alaska, USA collected as part of the NASA SnowEx 2023 field campaign. The study sites include a boreal forest environment in the Fairbanks region of central Alaska (the Bonanza Creek Experimental Forest, Caribou Poker Creek watershed, and Farmer’s Loop/Creamer’s Field) and a coastal tundra environment in the North Slope region of the northern Alaska coastal plain (Arctic coastal plain and Upper Kuparuk Toolik).
