| 摘 要： | 数字化区调中，在PRB资料入库前的几个阶段，容易产生一些误差，这些误差累积起来会产生较大的误差，影响野外数据采集的质量和精度.从数字化区调过程中的几个阶段分析了误差产生的原因，重点介绍了因多路径效应造成GPS的点漂移，形成GPS点与实际位置间的误差.采用软件修正的方法能减小因GPS点漂移产生的误差，从而提高野外数据采集的质量和精度.

| Abstract: | In the process of digital regional geological survey,errors occur commonly during the steps before the PRB data input.The accumulation of these errors will cause a greater error,which may affect the quality and accuracy of data collection in the field.This article analyzes the causes of the errors in each step of digital regional geological survey,particularly the error resulted from the point drifting of global positioning system(GPS) because of the environmental factors.The method of software amending is adopted to diminish the error caused by GPS drifting,and then to improve the quality and accuracy of data collection in the field. |

| Keywords: | digital regional geological survey error point drifting global positioning system |
