Application background
In physical measurement, the geodetic coordinate system is converted to spherical coordinate system. The geodetic coordinate system is based on the coordinates of an ellipsoid, first converted into the center of the earth's Descartes coordinate system, and then converted to the spherical coordinate system by the center of the earth's Descartes Cartesian coordinate system.Key Technology
Input file Input.dat format B L H, conversion of parameter ellipsoid ellipsoid long radius a=6378137m and flattening of the countdown for 298.257223563. The center was first converted to Cartesian rectangular coordinate system, and then further transformed into spherical coordinates, the output file is convert.datfortran
