| Abstract: | This paper firstly analyzed factors affecting the qu-ality of GPS field observation, and introduced the application situation of TEQC. The author preprocessed the data of two projects of Xibao and Chenggui, acquired the information of data quality which directly reflected the true quality of field observation data, thus, the authenticity and the reliability of the subsequent calculation results were more reliable. |
