Hybrid Method of Mapping and Photogeodetic Control Network Densification

摘要

During the past few years, tremendous progress has been made in aerial triangulation by block adjustment with additional parameters. This method has achieved reliability and accuracy not considered possible only a decade ago. This paper postulates that photogeodetic control densification is economically viable, especially when performed in conjunction with well-defined mapping tasks. Satellite geodesy, by means of the NAVSTAR Global Positioning System, is also discussed. This recently operational system is revolutionizing the approach to geodetic control densification by attaining survey results of centimeter-level accuracy.
