例如海底隧道港島出口的天橋群,青馬大橋的青衣出入口等.

SORRY, 各位行山好友,
我打錯了字"交匯點"應是"交匯法"是有關確認自己位置的一個方法來的.

好簡單講係你搵三樣野睇它的bearing之後將計到的加或減一百八十度,之後由那樣野跟那個角畫一條線三條線交叉的三角就是你的位置.如果唔明,請你去上山藝course.

阿F.A.兄有個花名,叫"人肉GPS",皆因佢上次在海下救牛事件上,就係用三角定位o黎講出隻牛o既正確位置(GR)俾警察聽,D警察隋磾笉PS黎到,發覺誤差只係一度咁多,所以話,大家與其花千幾二千蚊買個GPS,不如學識三角定位好過!

但我想問多少少的是:(交匯法)在畫線前是需要找三個景點及知道自己的位置才可用的?
感謝各位行山愛好者的解答.
我都好想上山試試用交匯法,但好多時是有一斑朋友喜歡行山但沒有時間行,有一班朋友較為有空閒卻不喜歡行山,
故行山之期就變得遙遙無期, 你們有試過這狀況嗎?

不用知自己位置,知就唔駛用啦,你用就係想搵自己係邊.但係你就一定要認到三個其他地型

our: 沒有,現在周圍到有行山隊,行山網站點會冇人陪你行山

其實用兩點已可定位,第三點是用來核準的.但原則是頭兩點和自身位置所構成的角度不可太少(~0度)也不可太多(~180度),最好是在45-135度內.而兩定位點最好有明確地型特徵,易認及在地圖有點示的.

墇上是一個經典的交匯點,通常交匯點都是一些四通八達,而且能夠作為中途休息的地方。

係唔係又叫「交叉定位(cross bearing)」?
