The final quality of all phototriangulations is characterized by
statistical parameters listed in Tables 1 and 2. Parameters such as root
mean square error (RMSE) of residuals of the GCPs and/or the total
sigma of adjustment (Table 1) were provided by bundle adjustment
and indicate very good internal consistency (i.e. precision) of
photogrammetric measurements. The true accuracy of photogrammetric
products was assessed by computation of residuals of
independent check points (points not used in the solution process).
