FUNCTION PROTOTYPE

    void   c_css2c(int, float *, float *, float *, float *, float *);

SYNOPSIS

c_css2c(n, rlat, rlon, x, y, z);

DESCRIPTION

n

The number of input lat/lon coordinates.

rlat

An array containing the latitudes of the input coordinates, in degrees.

rlon

An array containing the longitudes of the input coordinates, in degrees.

x

An array containing the X component of the Cartesian coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon coordinate (rlat[i],rlon[i]) for i=0 to n-1.

y

An array containing the Y component of the Cartesian coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon coordinate (rlat[i],rlon[i]) for i=0 to n-1.

z

An array containing the Z component of the Cartesian coordinates of the output data. (x[i],y[i],z[i]) is the Cartesian coordinate corresponding to the lat/lon coordinate (rlat[i],rlon[i]) for i=0 to n-1.

USAGE

c_css2c is called to find the equivalent Cartesian coordinates on a unit sphere to specified latitude and longitude coordinates. The coordinate of 0. latitude and 0. longitude is converted to Cartesian coordinate (1.,0.,0.). Latitudes and longitudes are assumed to be in degrees.

RETURN VALUE

c_css2c does not return a value.

ACCESS

To use c_css2c, load the NCAR Graphics library ngmath.
