摘要
探讨地图比例尺与遥感影像分辨率的关系,为特定比例尺制图选择适宜分辨率的遥感影像在遥感影像制图中极为重要。本文分析了人眼分辨率和比例尺精度、地图比例尺和影像分辨率之间的关系,以30 m分辨率的landsat5遥感影像、2.1 m分辨率的ZY-3遥感影像及0.5 m分辨率的Word View-2遥感影像进行实验,探讨了不同人眼分辨率下的遥感影像成图质量。得到了1∶M比例尺制图时的遥感影像分辨率的选择范围为(1×10^(-4)M,5×10^(-4)M),最佳遥感影像分辨率为2.5×10^(-4)M的结论,并用已有应用实例对其可靠性进行了检验,进而为我国基本比例尺制图遥感影像的选择提供了依据。
To discussion the relationship between the map scale and the resolution of remote sensing images,select the remote sensing images with appropriate resolution for a specific scale mapping is extremely important in remote sensing image mapping. This paper analyzed the relationship between the human eye resolution and precision of scale、the scale of the map and image resolution,experimented with Landsat- 5（ 30m）,ZY- 3（ 2. 1m） and Word View- 2（ 0. 5m）,discussed the quality of remote sensing image mapping in different eye resolution. Concluded the resolution selection range of remote sensing images in 1 ∶ M scale mapping is（ 1 × 10-4M,5 ×10-4M）,the optimal image resolution is 2. 5 × 10-4M,and tested its reliability by suing existed applications,Thus provided basis for the selection of remote sensing image of basic scale mapping.
