The data acquisition of digital urban management using RS, GIS and GPS technology

The paper studies how to use Global Position System, Geographic information System and Remote Sensing technology quickly and accurately to achieve digital urban management data. The main research contents as follows. Firstly, digital urban management mode was built, and the types of data in the urban management are different, according to different data type, different methods be made use to obtain the data of urban management. Then, based on computer, mobile computing technology, and spatial information science, the urban management data acquisition system was invented. Last, the system can be used to obtain the multi-source data of urban management.
