EZVol displays the stockpile volume in cubic feet, cubic yards, or cubic meters. The user can enter a density factor for the stockpile material, and the program will display the total weight of the stockpile.<br /> Display options include survey points, TIN (Triangulated Network) surfaces, contour plot of stockpile thickness, and 3-D solid mesh view. The 3-D display can be viewed at various angles, and at a range of vertical exaggeration scales. Interfaces exist for Trimble POS, enCampo, Laser Atlanta, or generic XYZ data.<br /> The user can display the survey points, the Delaunay triangles which form each TIN, a contour plot of stockpile thickness, or a 3-D solid mesh view of the stockpile. The 3-D display can be viewed at any of eight different angles, and at a range of vertical exaggeration scales.";
