Landsat Derived Historical Lake Extents for the Barrow Peninsula

This data set consists of Lake extent maps for the Barrow peninsula from five historical Landsat satellite images classified by a hierarchical classification system. Normalized Difference Water Index (NDWI) was calculated from the green and near infra-red bands and each lake was classified by an independently derived NDWI threshold value. The acquisition dates for the images were 13 July 1977; 5 August 1985; 8 July 1992; 1 July 2001; and 20 August 2008.
