摘要
数字线划地图数据是数字城市中最重要、使用最广泛的基础地理数据,它保存了各要素间的空间信息和相关属性信息。DLG的入库数据检查是建库过程中一个重要而繁琐的工作,它确保DLG入库的数据质量。本文结合我院航测制图中心生产的1∶1 000数字线划图为例,提出借助EPSCHECK模块的合理应用,可以实现我们DLG数据入库完整性、正确性、合法性检查的生产需要。实践证明使用EPSCHECK模块数据检查方法便捷高效。
DLG Data is digital city in the the most important,the most widely used basic geographic data,it has pre- served between the various elements of the spatial information and attribute information. DLG storage data examination is in the process of building databases is an important and complicated work, it ensures that the DLG storage data quality. Based on Aerial Survey Mapping Center for the production of 1 ： 1000 digital line graph as the example, proposed by EP- SCHECK module can realize reasonable application,we DLG data warehousing completeness,correctness,validity check production needs. The practice proves that the use of EPSCHECK module data inspection method, efficient and conven- ient, in favor of city building popularity of information needs.
