Alaskan Arctic Coastal Plain Polygonal Tundra Geomorphology Map

We mosaicked twelve LandSat-8 OLI satellite images taken during the summer of 2014, which were used in an object based image analysis (OBIA) to classify the landscape. We mapped seventeen of the most dominant geomorphic land cover classes on the Alaskan Coastal Plain (ACP):

value | class name

0 | No Data
2 | Coalescent low-center polygons
3 | Low-center polygons
4 | Nonpatterned Drained Thaw Lake Basins
7 | Drained slope
8 | Flat-center polygons
9 | High-center polygons
10 | Sandy barrens
11 | Sand dunes
12 | Ice
13 | Coastal saline waters
16 | Rivers
17 | Urban (i.e. towns and roads)
18 | Riparian corridors
20 | Ponds
21 | Small lakes
22 | Medium lakes
23 | Large lakes
