摘要： 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.

摘要： A tilt analysis method analyzing a tilt of a columnar object is disclosed. The tilt analysis method includes: acquiring a reference value on the basis of a first position of a reflector of a measurement target device attached to a column foot portion of the columnar object; acquiring, in response to an execution instruction, a column top value on the basis of a second position of the reflector of the measurement target device attached to a column top of the columnar object, the execution instruction being received by an input section and inputted via a column top value acquisition instruction section displayed on a display section of a terminal device; generating tilt information indicating in which direction the columnar object tilts based on the reference value and the column top value; and causing the display section to display the tilt information including graphic display.

摘要： A method of placing a slope staking tool including pickets, crossbeams, and a slope beam. The staking method includes: placing the pickets near an intersection C between a current ground and a plane S including a designed slope s; placing the crossbeams on the pickets placed, so as to cross the pickets; searching for a point where a height difference Δh between a predetermined point on the crossbeam and the plane S including the designed slope s, calculated by a surveying device, is zero; and placing, on the crossbeams, the slope beam inclined from the point where the height difference Δh is zero as found in the search step, toward the intersection C between the current ground and the plane including the designed slope.

摘要： A surveying system for assisting placement of a slope staking tool including a picket, a crossbeam, and a slope beam. The surveying system includes a design information acquisition unit configured to acquire design information including a designed slope; a current slope estimation unit configured to calculate a current slope in accordance with the results of surveying the current slope; a first intersection calculation unit configured to calculate a coordinate of a first intersection between the current slope and the designed slope using the current slope estimated by the current slope estimation unit and the design information, and to display the coordinate on the screen unit; and a second intersection calculation unit configured to calculate, using the surveying device, an altitude difference between any position on the crossbeam placed and a plane including the designed slope and to display the altitude difference on the screen unit.
