刍议航测大比例尺数据库库体检查

On quality check of large-scale database used in aerial survey

在城市航测数字化成图环节中,大比例尺数据库的库体检查一直是重点关注的对象。笔者通过实践,对数据库库体检查的方法及流程进行了分析和探讨,重点提出了分块作业、制作模板、双数据库模板接边检查的检查方法,实践证明:该方法能有效提升库体检查的效率,进一步保证了航测数字化成图的质量。

In the digital mapping of urban aerial surveys, the quality check of large-scale databases has always been the focus. Based on the practices, the author analyzed and discussed the methods and processes of database quality check, and put forward the methods of block operation, production template, and double database template edge inspection. It is proved that this method can improve the efficiency of database quality check and guarantee the quality of digital aerial mapping.
