The lake map for the State of Alaska was generated from selected Landsat acquired during summer seasons of circa 2000. Nearly 400 30-m resolution Enhanced Thematic Mapper Plus (ETM+) images were used to produce the lake map. The database contains over 38,000 lakes larger than 0.1 km2. The spatial coverage of the product is nearly the entire state except the Aleutian islands. The lake product is released at three different levels in response to lake size classes: * Level 1: large lakes greater than 10 km2; * Level 2: medium-sized lakes between 1 and 10 km2; * Level 3: small lakes between 0.1 and 1 km2. The Alaskan lake products are released in ArcView shapefile format.
