Abstract: The traditional precise engineering surveying is characterized by manual static discrete observation and geometric model solution,which cannot meet the requirements of large-scale infrastructure such as pavement and track,where need of wide-range,continuous,dynamic and high-precision surveying for these infrastructures' and systems' maintenance and management.The dynamic surveying based on multi-sensor integration technology and the cooperative computing based on multi-source spatial-temporal data are the important development directions for precise engineering surveying.First,the paper introduced the uniform and conversion of high-precision spatial-temporal datum,the multi-sensor synchronous control,the fusion of the observed data,the quality improvement of the surveying data and the feature extraction and recognition of the pavement cracks based on the three-dimensional image.Then,the progress of dynamic and precise surveying applications such as pavement roughness,rutting and deflection survey,as well as geometrical parameters of track,fastener status and rail damage detection are described.

Key words: dynamic measurement, precision measurement, spatial-temporal datum, multi-sensor synchronization
