Abstract: A rolling digital surface measurement apparatus which measures and records the second elevation differences between a plurality of sequentially oriented, regularly spaced, co-linear points which lie on the surface, and which then computes the elevations of those points relative to a datum line established relative to any two points in the sequence by assuming that the mean curvatures of the tested surface are equal to zero in order to remove the inevitable effects of error compounding.
