DEM/DOM成果质量检查研究

Research of DEM/DOM Quality Inspection

结合厦门市1∶2000航测4D产品的生产实践过程,论述了大比例尺数字正射影像、数字高程模型的生产流程,根据4D成果数据各自的特点和它们之间存在的关联性,实现对DOM、DEM数据进行交互检查,从而提高DEM/DOM成果的质量。

This text mainly introduce the method of the quality checking of DEM,DOM.There have many relationship among DOM,DEM,DLG,DRG,so use those characteristic,we can check the quality of the DEM,DOM,find more methods to improve the 4D production quality.
