| 摘 要： | 本文利用ADS40相机进行航空摄影,对海岛(礁)区域1∶2000比例尺成图精度进行了分析,比较了差分GPS与精密单点定位技术应用于ADS40航摄的精度。试验结果表明,ADS40相机可满足海岛(礁)大比例尺成图航摄的精度要求,缩短成图周期,精密单点定位技术的平面精度与差分GPS方法相当,高程精度较差,从工程角度考虑,海岛(礁)大比例尺成图时架设地面GPS基站比较稳妥。

Experiments about large scale mapping by ADS40 camera in areas of island and reef |

| Abstract: | In this paper,ADS40 camera was applied in large scale mapping aerial photography in areas of island and reef.Differential GPS and Precise Point Positioning technique were compared and analyzed.Experimental results showed that using ADS40 camera could meet large scale mapping accuracy in areas of island and reef.The method could get the same accuracy as DGPS method at plane direction,while in height direction the method could not get a satisfying result.It was advised that setting ground GPS station is needed in large scale mapping in areas of island and reef. |
