How do you identify a spur on a topographic map?

A spur is formed between two river valleys. In the case of a river valley, the greatest height is to the outer side and the land sinks down towards the inner side, where the riverbed is. In the case of a spur, the greatest height is to the inner side and the land sinks down towards the outer side of the spur.

What is the difference between Spurs and valley?

A spur is a ‘V’-shaped hill that juts out. A simple way to tell a valley from a spur when looking at contour lines is to remember that if the ‘V’ points uphill it’s a valley, if it points downhill it’s a spur.

What is spur in surveying?

What is spur formation?

Bone spurs are bony projections that develop along bone edges. Bone spurs (osteophytes) often form where bones meet each other — in your joints. They can also form on the bones of your spine. The main cause of bone spurs is the joint damage associated with osteoarthritis.

How can you tell if a map is a spur?

What is the difference between a spur and a ridge?

On a map, a ridge is depicted as two contour lines (often of the same contour) running side by side at the same elevation for some distance. When the lines converge, the ridge is falling in elevation, creating a spur.

How do you identify a spur?

A general rule for a ring main is that if you only have two cables in the back of an existing socket then it is ok to spur. However, if you have a radial circuit with two cables coming in and out, this may be the last socket on that circuit and already has a spur.
