Il disegno come tecnica autonoma di ricerca: CAD e modelli geometrici per il rilievo

Geometrical problems can be addressed, verified and solved by CAD, which means that design can be considered as an autonomous research and measurement technique in the study of geometrical models, by eliminating the ana/ytic calcuLations no longer needed because they are now implicit in CAD. The article considers a problem in research on simple geometrical models as a support to to topographic survey operations: the adjustment of closed traverses. After a careful analysis of the methods common/y used to adjust angular and linear measurements, a new data adjustment method is illustrated, which does not depend on the orientation of the traverse with respect to the reference Cartesian coordinates, thus making it possible to maintain the acijusted angles and to determine the minimum displacements olthe vertices proportional to the sides.

In questa ricerca si vogliono studiare e promuovere nuovi modelli, slegati da quello stocastico e conseguentemente dalle analisi probabilistiche, e orientati invece verso quelle problematiche affrontate con metodo empirico e con semplici modelli geometrici. Il problema specifico affrontato ultimamente è stato quello della compensazione empirica delle poligonali ed in particolare di quelle chiuse.
