經緯儀水平角正倒鏡觀測程序與計算討論

水平角正倒鏡觀測可以消除許多儀器誤差，也可以提升角度觀測之品質與可靠度。本文探討正倒鏡觀測不同程序之影響差異，以及化算時三種不同計算方式之隱含用意。 Observing in both direct and reverse mode of the theodolite, could remove severalinstrumental errors in the horizontal angle measurement. It is also capable in improving theaccuracy and reliability of the surveying. This short note discusses the meaning of differentoperation sequences, and also three different ways for deriving the angle from the directionmeasurements.
