Surveying The difference of levels between two stations A and B is to be determined. For best results, the instrument station should be closer to the higher station closer to the lower station equidistant from A and B as far as possible from the line AB closer to the higher station closer to the lower station equidistant from A and B as far as possible from the line AB ANSWER DOWNLOAD EXAMIANS APP
