1. First prepare your data. The data must contains easting (x), northing(y) and Join. The Join is a unique attribute that represents how the points connect to others. Point with the same join will a line. See my data below.

This tutorial shows how gridded surfaces and contour plans are created and used in Discover. A topographic dataset containing spot heights is used as the data source.
An Exercise in Surface Modelling and Analysis Elevation data, stored as a series of spot height points, are located in the table called SPOT HEIGHTS in the \Discover Tutorial \Surfaces folder. The objectives of this tutorial are to interpolate a surface grid and generate a contour plan, create a profile, determine grid slope and aspect, perform sun-shading and clip the grid to a region.
