which are constructed by locating points of equal metric distance along lines in various
directions. The shape and the pitch of the contour lines around points at different positions
over a general metric field are quite different. It is only of oval shape for contour close to
the point, and contours away from the point can take quite different patterns, which may
be even non-convex in shape over regions of rapidly changing metric. Indeed, there is not
