The Interpolation Surface is used for interpolating hydraulic results between cross sections. This layer cannot be edited directly. The interpolation surface is dependent on the cross sections, river lines, bank lines, and edge lines, which are all editable features. To see what the interpolation surface will look like, right-click on the XS Interpolation Surface layer and select Compute XS Interpolation Surface. An example triangulation for an interpolation surface is shown below.
