大比例尺DLG数据生产中若干问题的探讨

The Discussion of some Problems in Large-Scale DLG Data Production

大比例尺DLG数据是数字城市地理信息平台中最重要的基础地理信息数据,对于加快城市信息化进程具有重要的保障作用。制定合理的DLG数据生产工艺流程,精确配准影像,快速构建居民地及植被要素面,二次开发辅助程序,对提高数据质量,缩短项目生产周期具有重要意义,文章就以上问题,进行了详细的探讨与实践。

Large-scale DLG data is the most important basic geographic information data in the digital city geographic information platform.For the purpose of speeding up the process of city informatization,it played an important security role.Formulating reasonable DLG data production process,precise image registration,building residential areas and vegetation elements surface quickly,and the assistant program play important roles in improving data quality.The article made detailed discussion and practice about the above problems.
