Research offers expanded version of the relationship to improve measurement
accuracy (provided by Otrenbski), which include correlated or free geodetic networks, with
correlated or incorrelated observations, which are processed according to the Lea
st Square
theory. In addition to enhancing the Global accuracy, Research gives additional formula
takes into consideration the enhancement of each observation (local precision). the validity
of the proposed formula was proved depending on the Idempotent matrix.
In addition to the general concept of the reliability of geodetic network (described in
literature), Research gives the formula of the relationship between improvement of
measurement accuracy and one of internal reliability features (provided by Pelzer), and
used in the evaluation of geodetic measurements. Research find and gives the basic
mathematical indicators of the interaction of processing model with the occurrence of
errors in geodetic measurements.
The research aims to study the effect of weather (humidity - pressure - temperature) on
the linear measurements between geodesic network points through the introduction of
these factors directly on the Total station devices settings and get distanc
es patched for that
network has been based geodesic point (conducting field measurements necessary) within
easy reach of the design requirements of the device ideal conditions in the study area
(Trjano) in the province of Latakia, which we will adopt in the later stages to monitor
landslides and thus all measurement cycles will be compare basic measurement cycle
taking into account changes in ambient weather conditions in each measurement cycle for
the reference measurement cycle.
