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

     Produces polar stereographic maps / satellite views.

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

     satellite(map.obj,col="black",lwd=2,lty=1,add=FALSE,
                           las = 1,lon.0=NULL,lat.0=NULL,method="normal",
                           ni=100,nj=100, n.nearest=4,max.dist=3,landdata=addland2)

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

 map.obj: a map object (`mapField').

     col: contour colours.

     lwd: contour line width.

     lty: contour line style.

     add: FLAG: true adds contour onto old plot.

     las: see `par'.

   lon.0: Reference longitude: centre of map; NULL selects
          automatically.

   lat.0: Reference latitude: centre of map; NULL selects
          automatically.

  method: A choice between "normal","polarstereo", and "distance".

      ni: Number of grid points along x-axis in new grid.

      nj: Number of grid points along y-axis in new grid.

n.nearest: Number of points to use in re-gridding.

max.dist: The maximum inter-point distance used for re-gridding.

landdata: "addland" gives hiher resolution for coast lines, but is
          slower.
