任意の緯度・経度情報から、別の箇所の緯度・経度情報の「方位」を計算するAppleScriptです。
v1では、Satimage OSAXのインストールが必要でしたが、自前でObjective-Cで書いた「atan2だけを計算するフレームワーク」に置き換えたものです。
–> trigonometry.framework (To ~/Library/Frameworks/)
北を0として、西に向かうとマイナス、東に向かうとプラスの値で角度（方位）を返します。この手の計算に必須のatan2関数がAppleScriptに標準装備されていないため、atan2を呼び出すだけの簡単なCocoa FrameworkをObjective-Cで記述して、呼び出してみました。
