1. A surveying system for assisting placement of a staking tool including a picket, a crossbeam, and a slope beam, the surveying system comprising, in addition to a surveying device and a terminal device:
a design information acquisition unit configured to acquire design information including a designed slope;
a surveying information acquisition unit configured to transmit, to the terminal device, surveying information on surveying by the surveying device;
a current state estimation unit configured to calculate an estimated altitude of a current ground in accordance with the surveying information received by the terminal device;
an intersection calculation unit configured to calculate a coordinate of an intersection between the current ground and the designed slope based on the estimated altitude of the current ground and the design information including the designed slope;
a stake shape determination unit configured to determine a shape of a stake to be placed, based on a direction of the designed slope of the surveying information and on which side of the intersection in a horizontal direction a current surveying position is located; and
a stake shape information unit configured to cause the terminal device to inform of the shape of the stake determined by the stake shape determination unit.
