Landsat Derived Historical Lake Extents for the Barrow Peninsula

Alternative title(s)

106.298

Abstract

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.
