Terminal device, measuring instrument, measurement and investigating system auxiliary program

摘要

PROBLEM TO BE SOLVED: To provide a terminal device, a survey instrument, a survey system and a survey auxiliary program that realize reduction of time and labor required for work of turning a light emitting and receiving part to a subsequent survey point.SOLUTION: A terminal device includes: an acquisition part 22 that acquires a survey object coordinate which is a coordinate specifying a position of a survey point determined to be a survey object, from multiple coordinates specifying each position of different survey points; a communication part 24 that communicates with a survey instrument 12, which includes a horizontally-rotatable light emitting and receiving part 16 for emitting light to a reflector and receiving the reflected light; and a control part 26 that obtains a rotation angle required for turning the light emitting and receiving part 16 to a position specified by the survey object coordinate, on the basis of both light emitting and receiving part information showing a current position and direction of the light emitting and receiving part 16 and the survey object coordinate acquired by the acquisition part 22, and controls the communication part 24 so that instruction information for giving an instruction to turn the light emitting and receiving part 16 to the survey instrument 12 at the obtained rotation angle is transmitted to the survey instrument 12.SELECTED DRAWING: Figure 1
