This map layer contains a natural-earth image of Hawaii. The image is land cover in natural colors combined with shaded relief, which produces a naturalistic rendition of the Earth's surface. The data set is in an Albers Equal-Area Conic projection. The Natural Earth data were produced from existing National Atlas land cover, tree canopy, elevation, and satellite view data. This layer is part of the 1997-2014 edition National Atlas of the United States. The 100-meter resolution Natural Earth data were developed to portray the terrain and land cover of the United States at 1:1,000,000 scale. They are intended primarily for visual purposes. The original NLCD data or Landsat Thematic Mapper imagery data should be used for conducting scientific analysis, and the original NED data should be used for determining the most accurate elevation values. No responsibility is assumed by the National Atlas of the United States in the use of these data. National Atlas of the United States. (2013). 100-Meter Resolution Natural Earth of Hawaii. National Atlas of the United States. Available at: http://purl.stanford.edu/qd855xh2430. Included with the GeoTIFF are an information file (.xml), an auxiliary information file (.aux.xml), an image overview file (.ovr), a .tfw file (more information included below), and a .prj file (more information included below.) The contents of the associated world file (.tfw) are: >100.0 >0.0 >0.0 >-100.0 >-402950.0 >2164950.0 The projection (.prj) file contains the following information: > PROJCS["Albers_NAD83_ Hawaii ", >GEOGCS["GCS_North_American_1983", >DATUM["D_North_American_1983", >SPHEROID["GRS_1980",6378137.0,298.257222101]], >PRIMEM["Greenwich",0.0], >UNIT["Degree",0.0174532925199433]], >PROJECTION["Albers"], >PARAMETER["False_Easting",0.0], >PARAMETER["False_Northing",0.0], >PARAMETER["Central_Meridian",-157.0], >PARAMETER["Standard_Parallel_1",8.0], >PARAMETER["Standard_Parallel_2",18.0], >PARAMETER["Latitude_Of_Origin",3.0], >UNIT["Meter",1.0]] Data set extent in meters (Albers Equal-Area Conic projection) >North 2165000 >West -403000 >East 303000 >South 1723000 There are no NULL or NODATA values in the GeoTIFF. Instead, all oceans are assigned a RGB color of (193, 224, 250) (blue) and all non-U.S. land is assigned a RGB color of (240, 235, 211) (tan).
