The coordinate (1.,0.,0.) is mapped to the latitude/longitude coordinate (0.,0.). The latitude/longitude coordinates are returned in degrees. CSC2SD is a double precision version of CSC2S. .SH ACCESS To use CSC2SD, load the NCAR Graphics library ngmath. .SH SEE ALSO css_overview, cssgrid, css2cd, csc2s. .sp Complete documentation for Cssgrid is available at URL .br http://ngwww.ucar.edu/ngdoc/ng/ngmath/cssgrid/csshome.html .SH COPYRIGHT Copyright (C) 2000 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
