This raster layer is a georeferenced image containing impervious surface data for Hawaii. Data are in an Albers Equal-Area Conic projection and have a resolution of 100 meters. The impervious surface data were derived from the 2001 National Land Cover Database (NLCD) Percent Developed Imperviousness data set, a product of the Multi-Resolution Land Characteristics Consortium (MRLC). The MRLC is a multi-agency cooperative effort to study land cover change. This layer is part of the 1997-2014 edition of the National Atlas of the United States.The 100-meter resolution impervious surface data were developed to portray the impervious surface of the United States at 1:1,000,000 scale. They are intended primarily for visual purposes. The original NLCD data should be used for conducting scientific analysis.
