摘要
结合利用1∶10 000 DLG进行DEM生产及新的质量检查评定标准,介绍了如何进行DEM生产的过程质量控制和成果质量检查及如何进行单位成果质量评定,并应用于粤东区域约400幅1∶10 000 DEM更新项目中;介绍的质量检查内容与方法全面、可操作性强,对提高检查效率与成果质量有一定的帮助。
According the new quality inspection and assessment standard for digital surveying and mapping,the methods for process quality control and production quality inspection and assessment for producing 1:10 000 scale digital elevation model based on 1:10 000 scale digital line graphs were been introduced in the article.It was been used to the Guangdong East DEM renew project.The quality inspection contents were across-the-board and the methods are maneuverability and there are propitious to advance quality efficiency and production quality.
