Polygonal Tundra Geomorphology Map from Landsat time series, 2014, Alaskan Arctic Coastal Plain (US)

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
