The NED is a raster product assembled by the U.S. Geological Survey, designed to provide national elevation data in a seamless form with a consistent datum, elevation unit, and projection. Data corrections made in the NED assembly process minimize artifacts, permit edge matching, and fill sliver areas of missing data. The National Atlas also includes a Lambert Azimuthal Equal Area projection shaded relief file; this file is the same data in an Albers projection. Purpose: The grayscale shaded relief images were developed to portray the terrain of the United States. They are intended for visual purposes only. The original NED data must be used for conducting analysis and determining elevation values. Supplemental_Information: The associated world file is included as part of the GeoTIFF. The contents of the world file are: >200.0000 >0.000000 >0.000000 >-200.0000 >-402900.0000 >2164900.0000 The following projection file can be used when using ESRI's ArcGIS to view the GeoTIFF (any line breaks should be removed): PROJCS["Albers_NAD_1983_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]] Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 200603 Currentness_Reference: Publication date Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -163 East_Bounding_Coordinate: -152 North_Bounding_Coordinate: 26 South_Bounding_Coordinate: 15 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: elevation Theme_Keyword: imageryBaseMapsEarthCover Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: Digital Elevation Model Theme_Keyword: Shaded Relief Theme_Keyword: Topography Theme_Keyword: Topographic Theme_Keyword: DEM Theme_Keyword: NED Place: Place_Keyword_Thesaurus: None Place_Keyword: United States Place_Keyword: Hawaii Access_Constraints: None.

Process_Step: Process_Description: Four elevation mosaics were extracted from the National Elevation Dataset (NED) and used to produce the shaded relief images of the conterminous United States, Alaska, Hawaii, and Puerto Rico and the U.S. Virgin Islands. A separate image was created for each of the four areas because, at 200-meter resolution, file size for an elevation mosaic of all of the United States would exceed the processing capacity of some commonly-used GIS and image processing software packages. For Hawaii, elevation data were extracted from the NED and projected to an Albers Conical Equal-Area projection, with a pixel size of 200 meters. The datum for NED data is NAD83, except for Alaska which uses NAD27. Using the ArcInfo Polygrid command, a 0/1 land/water mask was created for Hawaii at the same 200 meter resolution as the elevation data, using coastline data clipped from the National Atlas shoreline file. The land/water mask was applied to the 16-bit elevation grid. The masked elevation grid as well as the mask itself is available on request. More information on the NED may be found by following the links at . Shaded relief was created from the masked land/water elevation data set using the ArcInfo Hillshade command with these parameters: >Azimuth 315 degrees >Sun angle 45 degrees >Vertical exaggeration factor 10 In Adobe Photoshop, oceans were set to (0,0,0). The masked image from Photoshop was saved as a TIFF, ingested into ArcInfo 's Grid module, saved as a TIFF from ArcInfo, and then processed through a USGS GeoTIFF software program to create a fully-compliant GeoTIFF with valid header information.
