Abstract: A technique for more reliably capturing a lost unmanned aerial vehicle in tracking the unmanned aerial vehicle by a surveying device is provided. A UAV search area setting part is configured to perform arithmetic operation for searching for an unmanned aerial vehicle having mounted therein a location identifying device using a GNSS. The UAV search area setting part includes a measured location obtaining part that obtains information of a location of the unmanned aerial vehicle, which is measured by a surveying device, a scheduled flight location obtaining part that obtains information of a scheduled flight location of the unmanned aerial vehicle from a flight plan of the unmanned aerial vehicle, and a search area setting part that sets an area for searching for the unmanned aerial vehicle by referring to a difference between the measured location and the scheduled flight location at a specific time.

Abstract: The efficiency of the work for measuring electromagnetic waves is increased. A measuring device includes a position information obtaining unit, an electromagnetic wave information obtaining unit, a data storage unit, and a selecting unit. The position information obtaining unit obtains position information of a reflective prism 202, which is measured by a position measuring device 400. The electromagnetic wave information obtaining unit obtains illuminance information measured by an illuminometer 203, which is in the proximity of the reflective prism 202. The data storage unit stores the position information of the reflective prism 202 and the illuminance information in association with each other. The selecting unit compares information of predetermined measurement planned positions with the position information of the reflective prism 202 and selects the illuminance information at a position that has a specific relationship relative to one of the measurement planned positions.

Abstract: A position guiding device includes a mobile terminal having an imaging part and display, a position information acquiring part for acquiring current coordinate information and target coordinate information, a direction sensor for acquiring direction information, and a controller to generate a target image. The mobile terminal is attached to a pole so as to position a pole tip within an angle of view. The controller acquires, from the position information acquiring part, current coordinate information representing a position at where the pole tip points, defines a horizontal surface including the pole tip as a measurement surface, generates corrected coordinate information by shifting the target coordinate information to a position on the measurement surface, generates the target image in which a target position marker is put at a position representing the corrected coordinate information in the image obtained by the imaging part.
