A laser rod surface elevation table (L-RSET) includes a sensor arm coupled to a stepper motor and a screw frame. A screw interconnects the motor and frame, while a screw carriage interconnects the screw and a sensor carriage. A laser sensor is mounted to the sensor carriage. A controller includes at least one processor operatively coupled to the sensor and motor. The processor processes measurement values in a data structure and performs functions to actuate the motor and sensor. The data structure represents a quasi-unique topographical measurement project, and is configured with the measurement values, including a radius value R which defines an area, a start point value X and a stop point value Y for positioning the screw carriage, a speed value S for speed of advancement of the screw carriage, an interval value I for measurement interval, and a points value N for points of measurement per measurement interval.

An augmented-reality system is combined with a surveying system to make measurement and/or layout at a construction site more efficient. A reflector can be mounted to a wearable device having an augmented-reality system. A total station can be used to track a reflector, and truth can be transferred to the wearable device while an obstruction is between the total station and the reflector. Further, a target can be used to orient a local map of a wearable device to an environment based on a distance between the target and the wearable device.

A technique is provided to enable check of a calibrated condition of a total station (TS) having a laser scanner in a surveying site. The TS includes an optical system for sighting an object, a laser positioning part that irradiates the object with laser light via the optical system to position the object, and a plane crossing location identifying part that identifies a crossing location of multiple planes constituting a three-dimensional structure as a first location, on the basis of the positioning result from the laser positioning part. The TS also includes a laser scanner that performs laser scanning in an area containing the crossing location, a plane crossing location calculator that calculates the crossing location as a second location on the basis of laser scanning data from the laser scanner, and a comparing part that compares the first location and the second location with each other.
