_D_e_s_c_r_i_p_t_i_o_n:

     Project Albers projection in plane to spheroid models of the
     globe.

_U_s_a_g_e:

     albersgeod(x, y, sph="Clarke1866", clon=-96, clat=23,
       sp1=29.5, sp2=45.5)

_A_r_g_u_m_e_n_t_s:

       x: Albers x-coordinate vector to be projected to
          latitude/longitude.

       y: Albers y-coordinate vector to be projected to
          latitude/longitude.

     sph: spheroid options: Clarke1866, GRS80, WGS84.  The default is 
          Clarke1866.

    clon: center longitude (decimal degrees).  The default is -96.

    clat: origin latitude (decimal degrees).  The default is 23.

     sp1: standard parallel 1 (decimal degrees).  The default is 29.5.

     sp2: standard parallel 2 (decimal degrees).  The default is 45.5.
