Abstract: A method of editing a surface representing a quantitative field is disclosed which facilitates getting a surface to conform to a required shape. In embodiments, the methods revise a surface display substantially in real time by altering a predetermined visual characteristic of the displayed surface as a function of changed original values, the predetermined visual characteristic comprising at least one of a contour line representative of a set of the changed original values or a one-to-one color mapping between a changed original value and color.
