实用型等高线数据检查系统

等高线数据的质量控制是各测绘生产单位作业中一个重要的环节。文中提出了一种条形码的检测方法，并将此方法与生产实际相结合，研制了一个实用的等高线数据检查系统。该系统可用于地面高程数据库入库前的检查验收。实践证明，这种方法可大大提高检查效率，方便了作业生产。

An Practical Checking System of Contour Vector Data

This paper puts forward a checking method based on bar codes and develops a suit of practical checking system combining with the practices. The system is applying to check and accept the elevation database before putting them into the database. Practices have proved that this method can greatly heighten the checking efficiency and facilitate the productions.
