Question

resection surveying prove

Answer 1

Resection is surveying technique that is used when the given points are not at all accessible but the new point is accessible then it is said to be resection method .

I am going to give you the resection method which are discussed below with diagrams , do check out the images that are attached to it for the calculation part as well .

RESECTION METHOD :

In this method look at the image that i have attached , the Point X is the current location of the new control station . In this we already have 3 points which have known coordinates

1. all of these points namely A , B and C which are visible from point X .
2. calculate the distance for AB and BC .
3. We are taking angles as , and .

SUMMARY

Using 3 point that is A , B and C with known coordinates , i have proved that the point X can be located by finding out the angle and bearing at the various locations. Hence i have proved the resection technique and provided all the necessary formula`s required for the calculation .
