Abstract:
GPS had been widely used in geodetic measuring, coordinate system retaining and monitoring of global plate movement or regional crustal deformation. However, some questions(reference models, systemic parameters, etc)are still unresolved in urban-land subsidence monitoring. This paper analyzes and compares the effects of different reference models, systemic parameters on adjustment result, and takes an adjustment model which adds systemic parameters and constrains. Finally, it compares with some schemes of adjusting the monitor network of land subsidence in Xi'an, and provides some valuable results of systemic parameters and different reference models.
