DEM构建过程质量控制
- Title:
- Quality Control During Building DEM
- Keywords:
- DEM; personal erro; landscape and geograph; quality control
- 分类号:
- TP79
- 摘要:
- 提高DEM精度，控制其质量是DEM构建者和使用者共同关心的问题。从如何减少DEM构建过程中的人为误差入手，对数字化过程中容易出现的人为误差进行了总结，指出相应的改进方法，并提出一种简便易行的快速检查DEM中错误的办法，对于指导生产实践有一定意义。
- Abstract:
- It is a mutual concerned problem for producers and users to improve DEM precision and control its quality.The authors begin with reducing personal error, conclude personal errors during digitize and point out corresponding correct methods.At the same time, a new method is advanced to check out DEM errors quickly.To some degree, the article can conduct the production.
