Abstract
Various problems associated with the adjustment of geodetic control networks in Eastern Canada are discussed. Results of analyses of the primary control networks in New Brunswick indicate that significant distortions are present and are due mainly to the Bowie Method of adjustment used when the 1927 North American Datum was adopted. The “free adjustments” made by the authors show that the proportional accuracy can be improved from the present lowest value of 1:20,000 to as high as 1:200,000. Other analyses cited in the paper indicate that there may be merit in combining first- and second-order control networks in a simultaneous adjustment. Some details are given on merging the first-order terrestrial networks in Eastern Canada with one triangle of the North American satellite triangulation network in a simultaneous adjustment.
