Surveying system, staking assistance method, and storage medium storing staking assistance program

A staking assistance method of assisting placement of a slope staking tool including a picket, a crossbeam, and a slope beam, using a surveying system including a surveying device and a terminal device with a screen unit, the staking assistance method comprising:

• design information acquisition of acquiring design information including a designed slope, using a design information acquisition unit;
• slope surveying of surveying a current slope in at least two points, using the surveying device;
• current slope estimation of calculating the current slope in accordance with a result of surveying in the slope surveying, using a current slope estimation unit;
• first intersection calculation of calculating a coordinate of a first intersection between the current slope and the designed slope using the current slope estimated in the current slope estimation and the design information including the designed slope and displaying the coordinate on the screen unit, using a first intersection calculation unit;
• and
• second intersection calculation of calculating, using the surveying device, an altitude difference between any position on the crossbeam placed and a plane including the designed slope and displaying the altitude difference on the screen unit, using a second intersection calculation unit.

A storage medium storing a staking assistance program of assisting placement of a slope staking tool including a picket, a crossbeam, and a slope beam, using a surveying system including a surveying device and a terminal device with a screen unit, the staking assistance program configured to cause a computer to execute steps comprising:

• design information acquisition of acquiring design information including a designed slope, using a design information acquisition unit;
• slope surveying of surveying a current slope in at least two points using the surveying device;
• current slope estimation of calculating the current slope in accordance with a result of surveying in the slope surveying, using a current slope estimation unit;
• first intersection calculation of calculating a coordinate of a first intersection between the current slope and the designed slope using the current slope estimated in the current slope estimation and the design information including the designed slope and displaying the coordinate on the screen unit, using a first intersection calculation unit;
• and
• second intersection calculation of calculating, using the surveying device, an altitude difference between any position on the crossbeam placed and a plane including the designed slope and displaying the altitude difference on the screen unit, using a second intersection calculation unit.
