Trignometrical stations for sec 1s @ 4:22 PM
Trigonometrical stations are key points that show the height of a hill or a mountain and is the highest point of the physical feature. On a topograohical map, the trig point will have the highest point value in metres. For more details and how it looks like, refer to your textbook page 34.
You can go this website at: http://en.wikipedia.org/wiki/Trig_point and to find out more why and how they are used refer to: http://en.wikipedia.org/wiki/Ordnance_Survey. At the bottom of the last website, you can find links to different organisations around the world that work on this surveying of our Earth.
Hint: I hear a test round the corner ask about the highest point.
