摘要
本文结合多尺度数字高程模型生产技术规定及数字测绘成果质量检查与验收制定的技术方案、技术指标和规程,以云南省全国第一次地理国情普查DEM精细化成果进行质量检查及成果质量评定为例,简要介绍了DEM的质量检查与评定方法,对成果质量判定工作和提高检查效率有一定帮助。
In accordance with the technical solutions, norm and specifications of the production and technical requirements about multi-scale digital elevation model and the quality check and acceptance about the digital mapping products, this article briefly introduce the quality check and assessment about DEM data in the first national geographic conditions general survey of Yunnan province; all the introduce about quality check is based on the quality check and acceptance about the digital mapping products totally, expect to be helpful to the quality control and improve the check efficiency.
