CONCLUSIONS
Accuracy comparisons were made for all four points that were set up as a part of a monitoring system. For
the comparison of accuracy of points GMX1, GMX3 and GMX4 the law of propagation of variances and co
variances was used. For point GMX2 comparison of accuracy could not be carried out by any of the two
procedures, due to the lack of input data. The accuracy comparisons carried out for point GMX1 have
shown that the observations made in hourly intervals are less precise than those made in daily intervals. The
precision of hourly observations is not sufficient in comparison with daily observations when using the
procedure
SAS 2
for adjustment. The results show that the sufficient match is achieved when using 4 .
