A surveying method using a surveying system including a surveying device and a terminal. The surveying method includes: receiving, by the terminal, a result of selecting a survey target foundation point from among a plurality of consecutive foundation points; obtaining an intersection between a reference line and a boundary side set in advance, the reference line connecting the survey target foundation point and an adjacent foundation point adjacent to the survey target foundation point; and outputting, in association with the survey target foundation point, a relative positional relationship between the intersection and a survey target device surveyed by the surveying device for the survey target foundation point.
