The development of the bundle adjustment with self-calibration advances photogrammetric technology to the stage where the densification of urban geodetic networks can be accomplished to requistie accuraciess from photogrammetric blocks of relatively small scale (1:17,500). This was demonstrated in a recent pilot project conducted in the City of Atlanta. Field checks showed that photogrammetrically determined coordinates of monuments had standard errors of better than 7 cm horizontally. The production of such high accuracies from photographs of such small scale renders the photogrammetric approach to densification overwhelmingly attractive economically in comparison with other methods of comparable accuracy. Although densification constitutes the indispensable first step to the development of the modern cadastre based on description of property by coordinates, progress to date in this regard has been disappointingly slow. We hope that the application of advanced photogrammetric technology will serve to stimulate progress.
