Explain the uses of stadia method.

The stadia method of traversing is useful in following situations:

1. In differential levelling, the backsight and foresight distances are balanced conveniently if the leval is equipped with stadia hairs.
2. In profile levelling and cross sectioning, stadia is convenient means of finding distance from level to points on which rod readings are taken.
3. In rough trignometric, or indirect levelling with the transit, the stadia method is more rapid than any other method.
4. For traverse surveying of low relative accuracy, where only horizontal angles and distances are required, the stadia method is a useful rapid method.
5. On surveys of low relative accuracy-particularly topographic surveys where both the relative locations of points in a horizontal plane and the elevation of these points are desired, stadia are useful.
