The spatial and group relationship of the friction ridge features to each other are determined in two manners.

 

First, by their 'Absolute Value', which is the ridge count between the features (i.e. 'three intervening ridges').

 

Second, by the 'Relative Positions' of the friction ridge features to each other (i.e. 'higher', 'lower', 'adjacent to' other features in the latent print impression).
