Abstract
A method of plotting and contouring grid surveys using a digital computer is described. Contour positions in each square element of a grid survey are determined by linear interpolation between the sides of the square. The resultant shape of ground surface is curvilinear, equivalent to a relaxation net between the sides which connect the four corner levels. Application of the method to surveys for flood irrigation design and other purposes is described, and a copy of the computer programme is given in the Appendix.
