Turning to the quantitative values of Table II, the same general trend is retained, 
where the criterion of the flat area is horizontal displacement in meters, and for the 
other two areas it is vertical discrepancy. 
Table III is designed to indicate a measurement of faithfulness of contour shapes. 
An analysis was made as outlined by Gerhard Lindig, "Neue Methoden der Schicht- 
linienprüfung,” in the journal Zeitschrift für Vermessungswesen, 1956, pages 244-251
