HSPTVAL
This attribute contains the elevation value of collapsed contours in
feet above MSL that are below the minimum capturable resolution for area
features on the ONC. For contours whose values cannot be determined, a
code of 99999 is used. The point coincides, where possible, with the
contour line itself and not with the center (FIGURE 6).
