一种适用于林业测量确定目标方位角的方法

A Suitable Method of Forestry Survey for Azimuth Angle of Ground Targets

介绍了一种不需查《中国天文年历》或《天文测量简历》而通过观测太阳天顶距来测定地面目标方位角的简单方法，这种方法可替代林业上常用的低精度罗盘仪定向．

This paper presents a simple method which is suitable for forestry survey, and can determine azimuth angle of ground targets through measuring solar zenithal distance without using“The Chinese Astronomical Yearbook”or“The Astronomical Observation Concise Handbook”. The method can be used in forestry survey instead of the method of low-accuracy compass orientation
