Distribution of standard errors of the x- and y-coordinates over the area 
So far only the means of the standard errors of the photogrammetric coordinates 
have been discussed. It is also interesting to investigate how they are distri- 
buted over the various points. This has been done graphically in case I (1:3500) 
(Figures 1, 2 and 3).
