Adjustment of altitudes by using observations of zenith angle with reciprocal and simultaneous readings

CLAUDIONOR RIBEIRO DA SILVA, ANTÔNIO SIMÕES SILVA

Abstract


Knowing the importance of the adjustment of observations for the topographical
and geodesic works, in this paper, the adjustment of zenithal angles with reciprocal
and simultaneous readings was used, seeking for estimated values for the altitudes
of the a set of marks. This work was accomplished in a polygonal belonging to the
Planimetric Network of the Brazilian Geodesic System (SGB) of first order. All the marks of that polygonal are placed at the campus of the Federal University of
Viçosa. The adjustment was performed by the Least Square Method. The parametric
model was applied, and the obtained results indicated that the procedure used was
satisfactory.
