GNSS VS Total Station) Base for Deformation Monitoring of Bridge Essay

GNSS VS Total Station) Base for Deformation Monitoring of Bridge - Essay Example To investigate the relationship between the surveying instruments GNSS and Total station and the difference in the effect of the deformation monitoring measurement of the dynamic Bridge. Additionally the aim is also to identify which instrument is more accurate and as it relate to deformation monitoring of the bridge Do a comparison of resultant data from both the GNSS and Total station as compared to GPS data and check for accuracy. To this end the dissertation will be divided into two parts. The first is a review of the importance of monitoring bridges for deformation, the problems that can occur with bridges over time, as well as the different categories of bridge contraction. This will set the background for the second part: comparing the use of GPS through GNSS and the use of total station monitoring for bridge deformation. While I was unable to meet with neither surveyors nor GPS operators, I will use other resources, such as online information, to compare these two instruments and present the results in an easy to understand
