| 摘 要： | 直接应用航空遥感象片进行面积量算，必然存在着某些误差。本文首先从理论上分析了这些误差的来源以及它们的计算方法，然后以实例数据对比，分析了这些误差的大小和对面积量算的影响情况，并讨论了应用航片直接进行面积量算的条件和应用范围，为在原航片上量算面积提供了计算数据和理论依据。

Precision Analysis of Area Measuring and Calculation on Aerial Remote Sensing Photos |

| Abstract: | There must be some errors if the area is measured through aerial remote sensing photo. This paper gives a theoretic analysis of the error sources and their estimation method. Then an example is discussed to compare the magnitude of the errors and their influence on the area measuring and calculation. The necessary conditions and the application scope are proposed to use aerial remote sensing photos onto the area measurement directly, which provides data and theoretic basis for the direct area measurement from the orginal photos. |
