Abstract：The problem by over considered for geodetic data precision in most of the researches on crustal deformation and earthquake prediction is analyzed. The problem might let so conservative as to some valuable information in the data are not fully utilized. Pursuing high quality of the data is right, but the first consideration should be how to fully use the historic data according to the reality and the requirements, because the historic data are not replaceable. Thus, it should do the best for mining information from the data, and not give up the chance to get information from it only due to more deviation of the data. Finally, this viewpoint is further demonstrated with the results in an example, utilization and analysis of velocity field of crust vertical movement monitored by GPS in Chinese continent from 1999 to 2009.
