Surfer 13 Topographic profile from DEM

Surfer's automatic profile tool makes it easy to visualize the change in Z value from one point to another. Simply select the map, add a profile, and draw the line on the map. Include as many points as you want in the line; it could be a simple two-point line, or a zig-zag shape. In all cases, the profile is created showing the Z value change along the length of the line. Reshape the line on the map, and the profile automatically updates.
