Atlas of the World with Geophysical Boundaries: Showing Oceans, Continents and Tectonic Plates in Their Entirety

Front Cover
American Philosophical Society, 1991 - Science - 92 pages
This atlas of world maps is divided into 3 parts: maps with continental shorelines as natural boundaries; composite maps with continental shorelines as natural boundaries; & maps with tectonic plate margins as natural boundaries. All graticules on the illus. are 15 degrees spacing unless otherwise noted & can be computer drawn. All projections, incl. land masses & plates, are suitable for computer drawing although, in some cases, some data have been entered by hand. Latitudes & longitudes are given for the poles of the map & for the center of the map. Latitudes are expressed in degrees north or south of the Equator; longitudes are given in degrees east or west of the Greenwich Meridian. Note that the poles of the map are the continental shoreline coincidences or plate boundary coincidences chosen for the particular map. Includes 29 four-color maps.
