DEM接边检查平差系统设计与实现

Adjustment System Design and Implementation of DEM Edge Examination

系统的开发与设计主要是解决生产的DEM文件中,相同X,Y点高程存在差异的问题。系统还可以检验DEM数据文件内部是否存在零高度点或无效值点,并且把检查结果以DAT文件(装有坐标的文本文件)的方式展现给操作者,为DEM生产的完整性做检验和平差工作。

The development of this system is mainly to solve the production and design of the DEM file,the same X,Y point elevation differences issue. System can also test whether there is an internal DEM data files or invalid value zero height point and the inspection results to the DAT file（ a text file containing coordinates） to show the way to the operator for the production of completeness DEM testing and work.
