Landsat Derived Historical Lake Extents

Abstract

Lake extent maps for the Alaska North Slope and Barrow peninsula were generated from selected Landsat satellite images between 1977 and 2008 available at the United States Geological Survey (USGS) database. The acquisition dates for the images are included in the individual filenames. The lake maps cover 400,000 km2 from 69.6dd N to 71.3dd N and -162.6dd W to -174.1dd W. The spatial resolution of the lake maps depends on the resolution of the Landsat image on which it was based. Landsat Multispectral Scanner (MSS) based maps have a resolution of 60 x 60 meters. Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) maps have 30 x 30 meter resolution. Lake extent maps are released in ArcView shapefile format. All files are projected in the UTM Zone 4 North with units of meters (m).
