Displacement of points determined by spatial intersection

Summary A procprocedure is presented for the direct determination of the components of the vector of spatial displacement of a point by spatial intersection. The horizontal, vertical and slope distances are determined by integrated surveying systems (electronic tacheometers), and the first survey is adjusted using conditional observations. The vector of displacement on the individual intervals of observation is determined by means of the matrix equation (33) into which it is only necessary to substitute the appropriate vectors of the observational differences.
