A practical contribution to the study of the effect weather on the geodetic control system during the monitoring landslides

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 distances 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.
