All planar structures are represented by a strike line and dip angle. 一切平面構造均可用向線和傾斜角來表示。
The biggest problem is calculating the seabed slope angle of the unknown seabed. 而對未知海底的傾斜角求解問題是解決波束角效應的難點之一。
When a position gyro is used in the pitch plane the missile is usually launched at a set elevation. 當位置陀螺用在俯仰通道上的時候，導彈通常以一個設定的仰角發射。
Back at the lab, technicians assign the frames latitude, longitude and elevation coordinates from U.S.Geological Survey ground references and scan dozens of frames into a computer. 回到實驗室，技術人員會參考美國地質調查所的地面資料，指出畫面拍攝的經緯度與仰角坐標，並把數十張畫面掃描到電腦里。
