Interactive network design
The availability of relatively inexpensive and powerful computer graphics terminals has inspired their application to horizontal survey network design. This thesis develops the naturally applicable sequential adjustment model for horizontal network design. The mathematical models for network observables, statistical considerations for error ellipse computation, and a comparison of directions and angles from the network design viewpoint are presented. An example using program NETDESIGN, which was developed to test the feasibility of interactive network design, is outlined. Examples using most of the mathematical models developed herein are given in the Appendices. The interactive design for horizontal networks is concluded to be an indispersible tool for surveying engineers, and it is recommended that it be fully developed and utilized.
