Abstract

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.
