OCR: Maps: Line drawing provided by William C. Clarke NOAA Global Shaded Relief, Small Blue Planet CD ROM, 12 October 92 This image was generated from a digital data base of land and sea floor elevations on a 5-minute latitude/longitude grid. Assumed illumination is from the west; shading is computed as a function of the east-west slope of the surface with a nonlinear exaggeration favoring low-relief areas. A Mercator projection was used for the world image. The resolution of the gridded data varies from true 5-minute for the ocean floors, the U.S.A ., Europe, Japan, and Australia to 1 degree in data-deficient parts of Asia, South America, northern Canada, and Africa. Data sources are as follows: Ocean Areas: U.S. Naval Oceanographic Office; U.S.A ., W. Europe, Japan & Korea: U.S. Defense Mapping Agency; Australia: Bureau of Mineral Resources, Australia; New Zealand: Department of Industrial and Scientific Research, New Zealand; Balance of world land masses: U.S.Navy Fleet Numerical Oceanographic Center. Computerized Digital Image and associated data base are available from the National Geophysical Data Center, National Oceanic and Atmospheric Administration, U.S. Department of commerce, Code E/GC3, Boulder, Colorado 80303.
