ABSTRACT

The article deals with a new adjustment of the trigonometric networks of Ist, IInd and
IIIrd orders which are part of the St. Stephen datum of cadastre coordinates on the
territory of Brno. Data for the adjustment were obtained from archival materials of the
Central Archives of Surveying and Cadastre in Prague. These materials were used to
retrieve information required to build new field books separately for each measurement
and adjustment of the trigonometric networks of Ist, IInd and IIIrd orders as a whole. The
input quantities were chosen to adjust horizontal angles and sides of known length
(bases). To compare the original and the newly adjusted coordinates of points
correlation parameters, resp. characteristics of accuracy, have been calculated. The new
adjustment of the St. Stephen datum of cadastre coordinates resulted in obtaining new
coordinates of points on the territory of Brno in the Czech Republic.
