Batter board placement method, batter board placement program, and survey system

A batter board setting method of setting batter board tools including a batter board stake, a batter board beam, and a leveling string, by use of a surveying system including a surveying device and a terminal device, the batter board setting method comprising:

• performing benchmark measurement including measuring a position of a benchmark that serves as a reference, by use of the surveying device;
• performing imaginary extension calculation including calculating an imaginary extension that is an extension of a foundation reference side indicating a point at which a leveling string is to be stretched out;
• and
• performing leveling string deviation guide including displaying a distance between a surveying position and the imaginary extension on the terminal device.

A storage medium storing program for setting a batter board including a batter board stake, a batter board beam, and a leveling string, by use of a surveying system including a surveying device and a terminal device, the storage medium storing program causing:

• the surveying device to perform benchmark measurement including measuring an altitude of a benchmark that serves as a reference height of the batter board;
• the surveying device to perform stake top measurement including measuring an altitude of a stake top of the batter board stake installed;
• and
• the terminal device to perform beam top position display including calculating a difference in height from the stake top of the batter board stake to a reference height of a foundation based on the reference height of the foundation stored in advance, the altitude of the benchmark, the altitude of the stake top of the batter board stake, and displaying the difference on the terminal device.
