Engineering survey basically does not need any advanced knowledge of mathematics and physics.

It is not difficult to have some theoretical knowledge. You will understand after reading the book. It doesn't matter if you don't understand. This course is very practical, as long as you can operate it.

The specific operation is also relatively simple. Basically, you just have to try it yourself and then test it once according to the formula in the book. After all the measurements, you can draw a picture and fill in several forms. Easy to master.

I hope it helps you.
