数字化等高线质量的软件自动检查方法

The Software Automatic Checking Methods for the Quality of Contour Digitizing

通过对国家基础地理信息系统 1∶ 5万 DEM建库中数据质量控制的方法研究及实践 ,提出了在数字化地形图生产 DEM过程中 ,解决等高线数据质量控制的两种技术方法 ,并介绍了其在 1∶ 5万 DEM数据库质量控制中的应用。

DEM database is one of the national geo-information systems. Through the study and practice of data quality control in the process of building that database, two kinds of technical methods of how to ensure the contour lines quality when digitizing topographic maps are discussed in this paper. Their applications are also introduced.
