Alaska Thermokarst Model Barrow Peninsula Geomorphology

We developed a 30 x 30 m resolution tundra geomorphology map (overall accuracy:75%; Kappa:0.69) for our ~1800 km² study area composed of ten classes to determine their spatial distribution across the Barrow Peninsula.

Legend:
value | class name

0 | urban
1 | lake
2 | river
3 | pond
4 | coalescent low-center polygon
5 | meadow
6 | low-center polygon
7 | flat-center polygon
8 | high-center polygon
9 | drained slope

An accuracy assessment is included.
