      Agnès,

      Variogram graphs for a number of directions can be represented in one map
      of contours. Looking at this variogram contour plot, if there is anisotropy
      the
      contour lines will make out the shape of an ellipse. The major and minor
      axis
      of the ellipse are then the two directions of minimum and maximum
      anisotropy.
      You can then plot normal variogram graphs for these two directions, fit your
      model to them (e.g. spherical) and input the parameters into your kriging
      software.
