The TIN have been created using max length = <define>rDUMMY</define> to ensure that the TIN has a convex hull (otherwise the routine that locates the triangle for a given location may fail). The TIN must also have been created using the Z values. Values located outside the convex hull are set to <define>rDUMMY</define>. Within each voronoi triangle, the Z value of node closest to the input X,Y location is returned.
