About Displacement/Delta Summaries
In order to satisfy the downstream criteria for the conflation method, individual vertices may be adjusted along the z axis up or down. You may request summary information about these adjustments such as the maximum, minimum, mean, and standard deviation of the displacements within a single output geometry or feature. The summary values are stored as attributes for the feature.
If the output feature class can store m values, individual delta values are stored in the m values for the output geometry. This can be useful for further investigations of offending vertices within the output geometry.
