大比例尺航测数字化测图内转外作业中的精度控制

The Precision Control of Inside-to-outside Procedure in Large Scale Digital Aerophotogrammetry Mapping

通过对某城区1:500航测数字化测图中,全数字摄影测量工作站上采集的数据按地形要素分类进行平面精度分析,找出不同要素的精度规律和影响精度的原因,在外业调绘修补测时采取针对性措施,保证最终成图的精度质量。

Through 1 ： 500 digital aerophotogrammetry digital mapping of some city area . This paper analysis the plane precision of the data classified by terrain elements in total digital aerophotogrammetry stations, and finds the precision rule and reason of effect precision of different elements , then adopt measures in field mapping to warrants the precision quality of final map.
