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

     Piezometric head measurements taken at the Wolfcamp Aquifer,
     Texas, USA. See Cressie (1993, p.212-214) for description of the
     scientific problem and the data. Original data were converted to
     SI units: coordinates are given in kilometers and pressure heads
     to meters.

_F_o_r_m_a_t:

     An object of the 'class'  '"geodata"', which is list with two
     components:

     '_c_o_o_r_d_s' the coordinates of the data locations. The distance are
          given in kilometers.  

     '_d_a_t_a' values of the piezometric head. The unit is heads to
          meters.
