摘要
介绍了点位数据质量检查工具TEQC软件及3种辅助绘图工具产生的历史背景、运行环境以及进行数据分析的方法和各自的优缺点;举例说明了TEQC软件对GPS数据进行转换、编辑与质量检查的步骤。结果表明,选择任意一种处理模式均可对点位数据进行质量分析。
This paper introduced the application of TEQC software in the GPS control network measurement. And it also introduced the historical background, operating environment and use of the TEQC software with three auxiliary drawing tools in point data quality check. Through several examples,it illustrated the procedures for TEQC software how to translate, edit and quality check GPS data. It analyzed the data analysis methods and their advantages and disadvantages about TEQC software with three auxiliary drawing tools followed with experiments. The results of the comparison showed that select any of the processing modes was available on the point of data quality analysis.
