Abstract
A target for surveying includes: a reference point and at least one first light emitting body disposed on a vertical line passing through the reference point; and at least one second light emitting body disposed on a horizontal line passing through the reference point and achieving light emitting characteristics different from the light emitting characteristics of the first light emitting body. A surveying instrument includes: a first reception device that receives signal light originating from the first light emitting body provided at a target for surveying according to claim 1 through a surveying objective lens; a second reception device that receives signal light originating from the second light emitting body provided at the target for surveying through the surveying objective lens; and an aiming control device that generates a first adjustment signal to be used to achieve aiming along a horizontal direction with the surveying objective lens based upon the signal received at the first reception device and generates a second adjustment signal to be used to achieve aiming along a vertical direction with the surveying objective lens based upon the signal received at the second reception device.
