Data Processing Methods Research And Software Development Of GPS Deformation Monitor

Deformation monitor is long-term and repeating survey work that aims at the point move conditions in monitoring the earth's surface, engineering buildings and establishment with its key point staying at catching the deformation information in the sensitive deformation positions and each periodic survey. GPS and other typical survey methods play an important role in this area. But comparing with the regular survey methods, GPS technology can not only meet the needs for accurate results of the survey, but also be helpful to the automation and real time of the survey. At present, the GPS technology has been applied to varieties of deformation monitoring, such as subsiding of the earth's surface in urban areas, deformation monitoring of the dams, deformation monitoring of bridges, monitoring for sliding slopes, tall buildings, mining areas, and so on.The methods of data processing to GPS monitor networks (here we mean the monitor network adjustment and the deformation analysis.) is not essentially different form the methods in the past, but more complex. As the deformation monitoring requires higher accuracy, massive data of information, the data processing is quite complicated. Therefore, it seems extremely important to develop such data processing soft wares with cooperating with GPS monitor survey, and furthermore bring it to the system of deformation monitor. From the above, we know that it is significant for deformation...
