A service vehicle with service equipment for performing a predetermined service operation in an operating area, the vehicle comprising positioning means to determine position information for navigating the service vehicle and/or the service equipment; monitoring means to acquire position-dependent operational data of the performing of the service operation in dependence on the position information; and reporting means to communicate the position-dependent operational data to a remote management server. The service vehicle is operable in a first mode, in which the positioning means provides the position information to the monitoring means which acquires the position-dependent operational data using the position information; the reporting means communicates the operational data to the remote management server; and the navigating is performed substantially independently of the position information.

A holder (1) for fixing a cylindrical spray can (2). The holder (1) comprises a holding unit (3) for fixing the spray can (2) with a first mechanical interface (4) for connecting a GNSS receiver (5) or prism to the holding unit (3). The holding unit (3) is adapted to hold the spray can (2) such that the GNSS receiver (5) or prism and the spray can (2) are arranged coaxially to each other. The holding unit (3) comprises a second mechanical interface (6) for releasably connecting the holder (1) to a frame (7) of a surveying cart (8).

A surveying instrument capable of irradiating a spotlight as visible light for centering toward a position below a vertical axis of a surveying instrument main body is configured such that that an irradiation shape of the spotlight is a toric shape. When visible light for centering which passes through a center point of the surveying instrument and is projected on a position right below the surveying instrument is projected in a toric shape having a hole opened at a center like a donut shape, both of an inner circle and an outer circle can be recognized, so that many guides are provided, and it is easier for a worker to align the toric shape with the target point than a point shape, so that the burden of a centering work on the worker is reduced.

A method of spraying paint using a painting assembly attached to a distance measuring wheel includes: receiving, by a communication device of the painting assembly, a control signal for controlling a driving device of the painting assembly; and based on the control signal, controlling a paint spraying state of a paint can attached to a paint can fixing device.
