The polygon represents the range of > acceleration values that are contained within its > borders. The polygon is assigned the lowest value > allowed within the polygon's borders. The range of > values allowed within a polygon is controlled by the > contours. Valid values are: 0,1,2,3,4,5,6,7,8,9,10, > 15,20,25,30,40,60,80,100 > >valley A topological indicator that tells whether the area > contained within the polygon is a local minima (valley) > or not. A value of "1" indicates the area is a local > minima. >LINE > >attribute description >========= =========== >acc_val Acceleration value in percent of gravity that the > contour represents.
